PS2P-LIN
Linear Touchless Hall-Effect Position Sensor
Piher Sensing Systems’ PS2P-LIN compact linear position sensor delivers true contact-free sensing for harsh industrial and vehicle environments in a low profile and robust magnetic design.
Magnet and sensor module are placed in separate housings without the need for any gears, bearings or linkages and can be placed anywhere on the moving object. This allows for easy mounting, thereby delivering additional cost reduction on the production line. Furthermore, without wear and tear of radial forces product reliability and lifetime are increased significantly.
The PS2P-LIN measures changes in linear position relative to the sensor by detecting the movement of a magnetized magnet that is located in a separate housing and is only sensitive to the flux density coplanar with the IC surface.
The PS2P series is complemented by touchless rotary (PS2P-CON) and play resistant arc (PS2P-ARC) position sensors. All sensors of the series are absolute sensors and will deliver the same level of precision and stability throughout their lifetime as on the first day they are installed – despite extremes of vibration, shock, temperature and contamination. For longer measurement ranges, Piher designs and manufactures long stroke inductive linear sensors.
