WS31 cable extension sensor

The WS31 cable extension sensor series with a new mounting bracket allows the easy and most flexible installation of the sensor and thus position measurement in almost every direction. The WS31 linear position sensor series offers measuring ranges of 10 and 20 inches and is well suited for many OEM production applications such as in medical testing equipment or in aerospace testing equipment. The series operates on the proven and reliable cable extension position sensor principal which 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 length of the cable that has been pulled out of the sensor by the moving object. The WS31 series is available with an analogue R1K, 4-20mA or digital incremental encoder A/B/Z output.
