Rotary position sensors

16 February 2011 Test & Measurement

These DC-operated rotary position sensors are also useful for high reliability applications such as pedal, throttle-lever or actuator position sensing in aircraft, marine, construction and agricultural vehicles.

Although their shafts can rotate a full 360°, the RSE 1500 series measures shaft angle position over a nominal range of 120°. Sensors can operate in 0° to 30°, 60°, 90° or 120° rotation ranges. Contactless inductive technology enables the sensors to offer high accuracy and repeatability as well as reliability. Units exhibit a linearity error of less than 0,10% of full range output while operating over temperatures from

-20°C to 85°C.

The RSE 1500 series sensors utilise built-in electronics to offer a DC input/output configuration. Operating from a nominal 24 V d.c. power supply, units supply a true 0–10 V d.c. output. The absolute output characteristic makes the RSE 1500 Series superior to incremental output sensors like optical encoders that lose their position information in the event of a power failure. Built for long life, units are enclosed in an anodised aluminium shell and have a stainless steel shaft running in high-performance ball bearings. The aluminium-mounting flange has a centre pilot for locating centrally in a fixture. Units are also environmentally sealed to IEC IP-66.
