When is a magnetostrictive sensor (POSICHRON) the right choice over a cable extension (POSIWIRE) or steel-tape extension (POSITAPE)?

Decision rule: accuracy, lifetime, and mounting form. Choose POSICHRON (magnetostrictive) when: • Contactless, wear-free is critical — high-cycle applications requiring millions of cycles (presses, injection moulding, production lines). • High accuracy required — ±0.02% f.s. linearity and 10 µm resolution. 5-10× better than cable extension. • Integrated inside hydraulic cylinder piston (rod-style PCST models) — sensor is protected inside the cylinder body, no external impact. • Underwater / high pressure — PCST27 pressure-proof up to 15 bar, cable extension can't survive this pressure. • Tight space — PCFP25's 8 mm flat profile fits where cable extension's spool doesn't. Choose POSIWIRE (cable extension) when: • Budget critical — POSICHRON typically 3-5× more expensive. • Low-medium cycle — a few strokes per hour, no need for millions of cycles. • Long stroke (above 5m) — POSICHRON max 5750 mm, POSIWIRE up to 50 metres. Choose POSITAPE (steel-tape extension) when: • Outdoor + dirt/ice/oil + medium cycle. • Mid-range stroke (max 20m). • Middle ground — more durable than POSIWIRE, more economical than POSICHRON. Rule of thumb: Hydraulic cylinder integration + high accuracy + high cycle → POSICHRON . Budget + long stroke → POSIWIRE . Outdoor + medium cycle → POSITAPE .

Profile selection: Square (PCQA), Round (PCRP), Flat (PCFP), Rod (PCST) — which goes where?

POSICHRON is offered in 4 form factors — selection follows mounting space + application type . Square Profile (PCQA — Quadratisches Aluminium): • Standard industrial mounting — externally mounted next to the machine. • Assumes wide mounting area, rugged aluminum housing. • PCQA22 (IP64): enclosed indoor, economical. • PCQA24 (IP67/IP69): outdoor, wash-down compatible. • Guided magnet option — magnet mechanically aligned to the profile. Round Profile (PCRP): • Round mounting area (e.g., beside cylinder body, on pipe). • PCRP21 (IP64): standard industry, compact round. • PCRP32 (IP68/IP69): continuous underwater operation, subsea. • Aluminum/stainless steel combination. Flat Profile (PCFP): • Tight mounting space — narrow machine cavities where a high profile doesn't fit. • PCFP23 (IP64, standard height): economical flat profile. • PCFP24 (12 mm height, IP67/IP69): mid-thin, wash-down compatible. • PCFP25 (8 mm height, IP67): the thinnest in class, plastic injection moulds + ultra-narrow OEM. Rod-Style (PCST — Stab): • Integrated inside hydraulic or pneumatic cylinder piston . • Cylinder body protects the sensor; magnet travels inside the piston. • PCST24/25 (IP67/IP69): standard hydraulic cylinder, dry environment. • PCST27 (IP68/IP69, 15 bar): underwater + high-pressure hydraulic. Decision table: • Wide area + external mount → PCQA (square) or PCRP (round) • Narrow horizontal area, thin profile → PCFP (flat) • Inside hydraulic/pneumatic cylinder → PCST (rod) • Underwater / high pressure → PCST27 or PCRP32

Hydraulic cylinder piston integration: what's the difference between PCST24 and PCST25?

Both are rod-style (Stab) form factor, designed to be integrated inside a hydraulic cylinder piston. The difference is in connection type : PCST24: • M12 8-pin connector standard (cable option also available). • CANopen version: 0.3 m cable + M12 5-pin connector. • Higher maintenance convenience — sensor swap means disconnecting the connector, no cable change. • Typical use: standard hydraulic cylinders, equipment with periodic maintenance. PCST25: • 2 m standard cable output (connectorless, permanent). • CANopen: 0.3 m cable + M12 5-pin connector (separate for CAN). • More economical installation (no connector cost). • Typical use: embedded installation, applications where sensor swap is rare. Decision: • Maintenance convenience, frequent swaps → PCST24 • Budget, permanent installation → PCST25 Shared features: • Range: 100-5750 mm (in 10 mm increments) • Sensor rod: 316L stainless steel (AISI 316L) • Head: AIMgSi (Aluminum/Magnesium/Silicon alloy) • IP: IP67/IP69 • Accuracy: ±0.02% f.s. • Output: 0-10 V · 0.5-10 V · 0.5-4.5 V · 4-20 mA (3-wire) · PMU programmable · SSI · CANopen • Shock: 50 g (100 shocks) Whichever is chosen, integration inside the cylinder piston is mechanically the same — only the external wiring differs.

Ultra-thin flat profile: how do I decide between PCFP24 (12 mm) and PCFP25 (8 mm)?

Both are POSICHRON's flat profile models for tight spaces. Decision follows height criticality + IP requirements . PCFP24 (12 mm height): • IP67/IP69 — usable in wash-down and washing environments. • 12 mm height — for medium-thin tight spaces. • Typical use: plastic injection mould cover position, compact OEM devices, food-processing lines. • Standard in ASM lineups since 2010. PCFP25 (8 mm height — thinnest in class): • IP67 (no IP69 — flat profile structure at 8 mm can't tolerate high-pressure wash-down). • Only 8 mm height — the thinnest magnetostrictive sensor in the industry. • Introduced by ASM in 2010 — launched for ultra-narrow mounting areas. • Typical use: microelectronics manufacturing equipment, pharma line narrow mechanism, robotic small-arm position measurement. • Limitation: cable output (connectorless) — due to limited access in tight spaces. Decision: • 12 mm available + wash-down required → PCFP24 (IP67/IP69) • Less than 8 mm + standard IP sufficient → PCFP25 (IP67, cable output) • Standard flat profile sufficient + budget → PCFP23 (IP64 standard flat) Shared features: • Range 100-5750 mm • Same output interfaces (Voltage / 4-20 mA / SSI / CANopen) • Accuracy ±0.02% f.s., resolution 10 µm • Magnet slides on profile — contactless, zero wear

Underwater / high-pressure applications: when is PCST27 (15 bar) mandatory?

PCST27 is the pressure-rated specialised model in the POSICHRON family. Standard PCST24/25 provide IP67/IP69 in oily environments but are not designed for continuous operation in pressurised fluid . PCST27 differs by: 1) 15 bar pressure resistance: The sensor body withstands continuous 15 bar hydraulic pressure. This equates to 150 m depth subsea . A standard hydraulic cylinder may have up to 200 bar internally — but that pressure is inside the piston; the sensor rod itself, which shares the cylinder body, does not see this pressure directly. 2) Water-proof cable seal: The cable entry at the sensor head is specifically sealed. A standard cable gland delivers IP67/IP69 but may leak over time under continuous 0.5-1 m water immersion. The PCST27 sealed cable entry guarantees permanent underwater operation. 3) IP68/IP69 combination: IP68 = continuous immersion (depth model-dependent). IP69 = high-pressure hot-water jet (wash-down standard). PCST27 provides both. Typical PCST27 applications: • Subsea hydraulic cylinders — ship bilge pumps, bilge level measurement, marine platform position control. • High-pressure tank level — chemical tanks, pressurised water reservoirs, hydraulic accumulators. • Mining shaft lift — continuous moisture + dust + pressure exposure. • Food-processing high-pressure cleaning — facilities with pressure above standard wash-down levels. Alternative: PCRP32: Round profile, designed for underwater operation. IP68/IP69, continuous immersion. But pressure rating lower than PCST27 (see datasheet for exact value). Different profile — PCRP32 is externally mounted, PCST27 integrates inside the cylinder. Decision: • Inside cylinder + pressurised fluid → PCST27 only option • External mount + continuous immersion → PCRP32 • Dry hydraulic cylinder + standard oil pressure → PCST24/25 sufficient

Position magnet selection: when is a guided magnet required?

In the POSICHRON family, the moving part the sensor reads is called the position magnet . The magnet travels along the sensor profile; the sensor reads its position contactlessly. Two magnet types exist: 1) Floating Magnet (Standard): Attached to the moving part, travels freely above the profile. Up to 19 mm gap between magnet and profile is tolerated (model + profile dependent). • Advantage: No contact between magnet and profile, zero mechanical wear. • Advantage: Flexible mechanical tolerance for the moving part. • Limit: Drift beyond 19 mm causes magnetic signal loss (false reading). 2) Guided Magnet: Magnet is mechanically aligned with the sensor profile — slides in a track attached to the profile. Distance is fixed , no drift possible. • Advantage: Maximum accuracy guaranteed (magnet always at the same distance). • Advantage: In high-vibration environments, magnet doesn't rub against the profile. • Limit: Mechanical contact exists (magnet in track) — continuous friction may eventually wear the profile surface, but this doesn't affect sensor electronics. When is a guided magnet required? • Moving part has tight mechanical tolerance — magnet drifts laterally/vertically, may exceed the 19 mm gap limit. • Maximum accuracy needed — precision position control, measurement equipment, quality control. • High-vibration environment — presses, hammers; a free magnet may fly off due to vibration. When is a floating magnet sufficient? • Moving part travels straight, the gap to the profile stays fixed. • Mechanical tolerance is 5-10 mm, well within 19 mm. • Cost-critical (guided magnet is more expensive). Which models offer guided magnet? PCQA22, PCQA24, PCRP21, PCFP23, PCFP24, PCFP25 — all profile-style models. Rod-style (PCST) models integrate the magnet inside the piston, so the "guided" concept doesn't apply. For site-specific magnet selection, contact IMB Electric engineering support.

POSICHRON output interfaces: what's the difference between PMU programmable analog and SSI digital?

The POSICHRON family supports a wide output range meeting modern industrial standards — more options than POSIWIRE, because magnetostrictive technology naturally supports high-accuracy digital outputs. Analog Outputs: 0-10 V Voltage: Standard analog. Accuracy depends on PLC card quality. Short-medium distance (≤100 m). 0.5-10 V or 0.5-4.5 V Voltage: Automotive standard. Easy fault detection on PLC (0 V indicates error). Common in mobile machinery controllers. 4-20 mA Current (3-wire): Most robust analog option. Noise-immune up to 1000 m. Industry-standard default. PMU — Programmable Analog (PMUV / PMUI): Voltage or current output, user-programmable upper/lower limits . Example: PCQA24's 100-5750 mm physical range, if only 500-2000 mm is used, can be PMU-mapped to 0-10 V output. The sensor utilises full dynamic range, accuracy increases. • Advantage: Maximum resolution + flexibility. Same sensor adapts to different stroke ranges across applications. • Limit: Requires initial PMU software programming (USB or CAN). Digital Outputs: SSI 12/14/16 bit: Synchronous Serial Interface. Accuracy 16 bit = 65,536 steps . Requires PLC SSI input card (Siemens, Allen-Bradley, ABB available). Zero noise, highest accuracy. • POSICHRON SSI resolution: 5, 10, 20, 50 or 100 µm selectable. • Typical use: high-end CNC, robotics, precision press applications. CANopen: Automotive industry standard. 127 sensors per bus. Available on PCQA22/24, PCRP21, PCFP series, PCST24/25 and specials. • POSICHRON CANopen resolution: 50 µm (fixed). SAE J1939: Heavy-vehicle standard (truck, tractor, off-highway). Decision table: • Standard factory interior → 4-20 mA • High accuracy, PLC has SSI card → SSI 16 bit • Mobile machinery → CANopen or J1939 • Same sensor across different strokes → PMU programmable • Automotive 0.5-4.5 V compatibility → 0.5-4.5 V

What are the POSICHRON warranty, calibration, and IMB Electric regional support conditions?

Warranty: ASM Sensor offers a 2-year manufacturer warranty on all POSICHRON models. Out-of-warranty cases: • Use outside datasheet limits (temperature, pressure, IP) • Mechanical impact damaging the sensor rod • Floating magnet used where guided was needed, rubbing the sensor profile • Unauthorised opening or repair • Pressure above 15 bar on the PCST27 model Calibration: POSICHRON is based on magnetostrictive technology — no mechanical wear, so calibration intervals are long . Typically 5-10 years . For field verification: • Sensor signals measured at full range (max stroke) and 0 position. • Must remain within ±0.02% f.s. linearity. • IMB Electric provides accredited calibration services in Türkiye (TÜRKAK scope). Sensor replacement: POSICHRON is contactless — no wear, no self-degradation. Failure mode is typically external impact (rod breakage) or over-temperature (outside datasheet limit). Magnet life: Standard position magnet (neodymium/ceramic) is long-life — magnetism doesn't fade. Only limit is high temperature (>150°C demagnetises neodymium) — in such cases, high-temperature magnet (samarium-cobalt) is preferred. IMB Electric Regional Support: IMB Electric is listed for Türkiye on ASM Sensor's official global distribution network , with authorisation extending to Türkiye + the Middle East + North Africa + Western Asia . Regional services: • Stock delivery (İstanbul İkitelli OSB) • Fast quotation (24-48 hours) • Accredited calibration and repair (TÜRKAK scope) • Application-based engineering support — sensor selection, hydraulic cylinder integration assistance, magnet selection, certification documentation • Local management of warranty processes • Turkish + English + Arabic (for the Middle East) technical documentation • Field training (on request) Contact: info@imbelectric.com · +90 212 544 59 59 · imbelectric.com

How do I use a POSICHRON sensor with a slider element (linear slider)? What is a push rod?

POSICHRON magnetostrictive sensors operate on the principle of a position magnet moving along the sensor rod. In some applications, the moving part cannot directly reach the magnet — in this case, a push rod (slider element) bridges the gap. How Push Rod Solution Works: POSICHRON sensor rod is mounted next to/under the equipment. Position magnet slides along the sensor rod (unguided or guided). PCGS push rod connects the magnet to the moving part — works like a push bar. PCGK link at the push rod end joins to the moving part — articulated connection. When the moving part rotates or translates, the push rod carries the magnet along the sensor rod. PCGS Push Rod Sizes: Length 75-499 mm — short stroke applications Length 500-1249 mm — medium stroke Length 1250-2000 mm — long stroke Each size includes the PCGK link. Typical Push Rod Applications: Hydraulic cylinder position: POSICHRON sensor next to the cylinder body, piston tip moves — push rod carries magnet to piston position. Press table slider: Press table moves, sensor beside the table — push rod connection. Valve position feedback: External position measurement of valve body — push rod pulls magnet from valve stem. Lift door position: Sensor beside door + push rod linked to door motion. Push Rod vs Direct Mounting — Decision: Moving part passes directly beside the sensor rod → Position magnet directly mounted (push rod not needed, economical) Moving part on a separate axis from the sensor rod → Push rod solution needed Travel distance exceeds 2 metres → Push rod not mechanically suitable, use alternative technology (POSIWIRE or POSITAPE) Advantages: Adapts to complex-geometry applications Tolerance for angular misalignment between sensor and moving part Isolates moving-part vibration/shock from sensor Disadvantages: Push rod length can reduce measurement accuracy (mechanical oscillation) Extra mechanical component → additional maintenance point Cost increase (push rod + link) IMB Electric engineering team provides push rod selection + installation consulting.
