Potentiometric Linear Transducer Series SPI18

Potentiometric linear transducer in a compact industrial design

In the displacement sensor series SPI18 the mechanical detection of linear movement is done by a front guided push rod with accurate sleeve bearings. To avoid vertical or angular misalignment in the mechanical coupling, ont the push rod a link ball is mounted. Due to his compact industrial design with 18x18mm in the profile and his front guided push rod construction a space saving integration can be reached up to 200mm 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 SPI18 has four fixing clamps which are included in the scope of supply. The SPI18 sensor is available with plug or cable connection.
