PRHY12 www.vishay.com Vishay MCB Analog Displacement Sensor for Mounting in Hydraulic Cylinder FEATURES • Conductive plastic potentiometer technology. Infinite resolution • Precious metal multi-contact wiper • Light alloy profiled support • Wire or connector outputs • Material categorization: for definitions of compliance please see www.vishay.com/doc?99912 This sensor is designed to be integrated into a hydraulic cylinder. Due to its small diameter, it can be fitted in the rod of small cylinders. The geometry of the profile and wiper is perfectly suited to operation at an optimum speed under all oil viscosity conditions encountered in the temperature range.
