About the RSE RVDT

The RSE series of contactless, fractional-turn, absolute output rotary position sensors are ideal for measuring the position of quarter-turn valves, flue dampers, weir gates, mail sorters, conveyor check weighing systems, dancer arm tensioners, and a myriad of other applications involving fractional-turn shaft movements. They are also useful for high reliability applications such as pedal, throttle-lever, or actuator position sensing in aircraft, marine, construction, and agricultural vehicles.

RSE 1500 series sensors provide an analog voltage output proportional to shaft rotation over a total range of 120°. They utilize built-in electronics offering DC input/output configurations and are available for 0° to 30°, 60°, 90°, or 120° rotation ranges with a true 0-to-10 V DC unipolar output. Normal electrical I/O termination is a 5-pin M-12 connector receptacle, but on special order for OEMs other connectors or cables can be supplied. Please contact us for more information. RSE 1500 series rotary sensors are enclosed in a 1-1/2 inch diameter anodized aluminum shell, and have a 0.250 inch stainless steel shaft running in high performance ball bearings.
