Linear sensors PWA

The PWA linear sensor model measures the absolute position of the piston without contact or wear using an inductive resonator system. This consists of an excitation coil that causes an oscillating resonant circuit (moving target) attached to the piston to oscillate. This in turn awakens the receiver coils fixed in the housing, which are printed on a printed circuit board. The integrated electronics convert these signals (sin/cos) into a signal proportional to the linear motion. The measuring system is insensitive to electric and magnetic fields. 0 (4) to 20 mA and 0 to 10 VDC are available as standard analog signal outputs. CANopen, IO link and SSI are under preparation. The sensor is fixed with at least two fixing clamps HK-01 or with sliding blocks ST-01. The sensor can be equipped with front and rear ball joints. Alternatively, the sensor piston can be designed as a button.
