Analog Displacement Sensor for Mounting in Hydraulic Cylinder
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.
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
Note
• Nothing stated herein shall be construed as a guarantee of quality or durability.
