RSE 1500 rotary position sensor.

RSE 1500 rotary position sensors from Macro Sensors measure the position of quarter-turn valves, flue dampers, weir gates, dancer arm tensioners, and other applications involving fractional-turn shaft movements.

These DC-operated sensors provide absolute output proportional to shaft rotation over a total range operating in 0 to 30 degrees, and 60-, 90-, or 120-degree ranges. Contactless inductive technology ensures high accuracy and repeatability.

Units exhibit a linearity error of less than 0.10% of full range output while operating over temperatures from -20 to 85 degrees C.

Operating from a nominal 24-V DC power supply, the units provide 0 to 10-V DC output. And they’re built for long life in a 1-1/2-in. diameter anodized aluminum shell with a 0.250-in. stainless steel shaft running in high performance ball bearings. The aluminum-mounting flange has a 0.750-in. diameter centre pilot for locating centrally in a fixture. Units are also environmentally sealed to IEC IP-66.

Macro Sensors is a Pennsauken, NJ-based manufacturer of industrial sensors.
