ASM Displacement Sensor Models Overview

ASM offers a comprehensive range of displacement sensors across multiple series, tailored to diverse industrial applications. Below are the key model categories and their characteristics:

I. Draw-Wire Displacement Sensors (Wegseil Sensor)

1. WS Series

• WS10: Entry-level model for short-range measurements (e.g., WS10-1250-10V-L10 with a 1,250 mm range and 10V output).

• WS12: Long-range variant (e.g., WS12-3000-420A-L10 with a 3,000 mm range and high-precision output).

• WS17KT: Ultra-long-range model (e.g., WS17KT-15000-PMU-L10 with a 15-meter range and magnetic absolute encoder technology).

• WS19KT/WS19KK: High-performance models supporting industrial protocols like HSSI and CANopen, ideal for high-speed dynamic measurements.

• WS58C: Compact design with IP68 protection, suitable for harsh environments.

• WS10SG: High-precision model with ±0.01% linearity and ranges from 100 mm to 1,000 mm.

2. Other Draw-Wire Models

• WS31/WS42: Cost-effective options for general industrial automation.

• WS7.5/WS60/WS100M: Ultra-long-range models with measurements up to 100 meters, designed for large-scale equipment monitoring.

II. Magnetostrictive Displacement Sensors

1. PC Series

• PCFP23/PCFP24: Non-contact measurement for hydraulic cylinder position feedback, with ranges from 50 mm to 5,750 mm.

• PCQA22/PCQA24: Explosion-proof variants for hazardous environments like petrochemical applications.

III. Magnetic Scale Displacement Sensors

1. PM Series

• PMIS4/PMIR7: Magnetic incremental encoders supporting SSI and CANopen protocols, with resolutions up to 1 μm.

• PMAG20/PMAG21: Magnetic absolute encoders featuring wear-free design and a lifecycle of up to 100 million cycles.

2. Other Magnetic Scale Models

• PRAS1/PRAS2: Angular displacement sensors for rotary machinery monitoring.

• PRDS3/PRDS6: Explosion-proof angular displacement sensors for explosive environments.

IV. Specialized Application Models

1. WS10EX/WS12EX: Extended models for extreme conditions like high temperatures and pressures.

2. LR19: Heavy-duty draw-wire sensor with a 15-meter range, ideal for construction machinery and port equipment.

3. AWS1/AWS2: Miniature draw-wire sensors for space-constrained applications.

V. Model Selection Guidelines

• Short-range, high-precision: Prioritize WS10SG or WS12 series.

• Long-range, harsh environments: Opt for WS17KT or WS19KT series.

• Non-contact measurement: Choose PC series magnetostrictive sensors.

• Rotary machinery monitoring: Consider PRAS or PRDS series angular displacement sensors.
