Linear displacement sensor WPA-A

contactlessmagnetostrictiveanalog

Product overview
Contactless linear position transducer based on HYPERWAVE magnetostrictive technology. The absence of electrical contact at the cursor eliminates wear and ensures long service life. Designed for high ingress protection and strong EMC immunity, suitable for harsh industrial environments.

Main features

• Optimised aluminium profile mechanical structure
• Available strokes: 50 to 4000 mm
• Sliding or floating magnetic cursor; single- or double-cursor versions
• Multiple analogue output options (voltage or current) for direct position or position+speed measurements
• Connector and cable options (M12, DIN connectors, PVC/PUR cables)
• Supply voltage: 24 Vdc ±20%
• Vibration resistance: tested to DIN IEC68T2/6 (15 g)
• Ingress protection: IP67
• Operating temperature: -30 °C to +85 °C
• EMC: compliant with directive 2014/30/EU
• RoHS: compliant with directive 2011/65/EU

Applications and environment
Intended for high-accuracy linear position measurement in industrial automation, machinery and harsh environments where contactless operation, long lifetime and EMC immunity are required.
