TE Connectivity SP2-50 Position Sensor, Resistive Position, 50" Range, SP2 Series

The SP2-50 provides a resistive voltage-divider output. As the cable extends or retracts, the internal potentiometer changes resistance, producing a proportional analog voltage signal when connected to a suitable excitation voltage (up to 30V). This output can be directly read by PLC analog input modules, data acquisition systems, or microcontroller ADCs with appropriate signal conditioning.

This sensor has an IP50 rating. The '5' indicates protection against limited dust ingress (dust-protected), and the '0' means it is not protected against water ingress. This rating makes it suitable for indoor industrial environments where it may encounter light dust and incidental splashes, but it should not be installed in wet or washdown conditions.

Mount the sensor body securely using the provided stainless steel bracket and mounting holes. Ensure the measuring cable can extend and retract freely along its axis of motion without Sharp Microelectronics bends or obstructions. The cable end should be attached to the moving object. Avoid exposing the cable to excessive lateral force or abrasion to ensure long-term accuracy and cable life.

Accuracy (±0.25% FS) refers to the maximum deviation between the sensor's reported position and the true physical position across its entire 50-inch range. Repeatability (±0.02% FS) is the sensor's ability to return to the same output reading when approaching the same physical position repeatedly. High repeatability is critical for closed-loop control systems where consistency is more important than absolute global accuracy.
