ASM POSIWIRE® WS31-500-R1K-L35-1 draw-wire cable extension position sensor captures linear position incrementally using a measuring cable made from stainless steel. Posiwire® cable extension sensors with magnetic absolute encoders are more robust than conventional cable sensors. The contact-less, magnetic multihall encoder technology is wear-free, and resistant vibration and shock. Therefore these sensors provide maximum performance especially in challenging envirenmental conditions. Also, this sensor is featured with different versions. Analog output, SSI output, Analog output with magnetic encoder, programmable analog output with magnetic encoder, digital output SSI with magnetic encoder, digital output CAN bus with magnetic encoder and incremental encoder output can be included to the product versions.
