Potentiometric Linear Transducer Series SPR18

Potentiometric linear transducer in compact industrial design

In the displacement sensor series SPR18 the mechanical detection of linear movement is done by a front and rear guided push rod with accurate sleeve bearings and outside spring return device. This construction makes the SPR18 sensor robust for linear motion operation with spring return device. Due to his compact industrial design with 18x18mm in the profile and his spring return device a space saving and easy integration can be reached up to 100 mm measurement stroke. To ensure high accuracy and long lifetime for a good price performance ratio the potentiometric measuring principle is realized with a high-resolution conductive plastic resistance element. Since the potentiometric measuring principle delivers absolute values and requires no electronic conversion, the position feedback signal is true power on without delay, temperature stable and robust against EMC influences.  For mounting the SPR18 has four fixing clams which are included in the scope of supply. The SPR18 sensor is available with plug or cable connection.
