SPR18 - Potentiometric Linear Transducer Spring return

Special Features

• In a compact industrial design
• Front guided spring return push rod and ball joints
• Long lifespan 20 million movements, and accuracy ±0,1%
• Linear potentiometer with almost infinite resolution
• Measuring lengths from 25 mm to 100 mm

In the displacement sensor series SPR18 the mechanical detection of linear movement is done by a front guided push rod. On the push rod a ball joint is mounted to avoid vertical or angular misalignment in the mechanical coupling. Due to the compact and robust industrial aluminium design in 18x18 mm profile measurement stroke can be reached up to 100 mm. The SPR18 sensor is available with plug or cable connection.
To ensure high accuracy and long lifespan 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. Customization on the cable (length, finishing with plug) or on the push rod (length, thread, flat ...) are available on request.
