ASM WS31 cable extension sensor series

ASM’s WS31 cable extension sensor series includes a mounting bracket for easy flexible installation of the sensor and thus position measurement in almost every direction.

The linear position sensor series offers measuring ranges of 10 and 20″ and is suitable for many OEM production applications such as in medical testing equipment or in aerospace testing equipment.

The WS31 series operates on the cable extension position sensor principle that uses a highly flexible stainless steel cable that is drawn onto a cable drum. An internal spring maintains the tension in the cable and ensures that the cable is recoiled exactly as a single layer on the drum. The output signal is proportional to the length of the cable that has been pulled out of the sensor by the moving object. The WS31 series is available with an analog R1K, 4-20 mA or digital incremental encoder A/B/Z output.
