Absolute linear transducer Model series PWA Data sheet No.: PWA 13535 JE Date: 05.02.2019 sensor system  Measuring length: 200 mm  Housing material: Aluminium  Protection type IP67 / IP54  Housing cross-section: 25 mm x 25 mm  Accuracy: ± 0.05%  Programmable measuring range Design The linear transducer model PWA measures the absolute position of the plunger without contact or wear using an inductive resonator measuring system. This consists of an excitation coil which causes an oscillating resonance circuit (moving target) fastened to the plunger to oscillate. This in turn excites the receiver coils fixed in the housing, which are printed on a printed circuit board. The integrated electronics transform these signals (sin/cos) into a signal proportionate to the linear travel. The measuring system is insensitive to electrical and magnetic fields. 0(4) to 20 mA and 0 to 10 VDC are available as standard as analogue signal outputs. CANopen, IO link and SSI are in preparation. The sensor is equipped with ball joints at the front and rear. TWK-ELEKTRONIK GmbH Bismarckstraße 108
