Rotary position sensors

4 November 2015 Test & Measurement

The RTP range of Hall-effect rotary position sensors from Honeywell provide non-contact sensing in harsh transportation and industrial applications at a competitive cost.

The magnet (in a choice of bare or housed format) is separated from the sensor body, while the absence of an actuator shaft removes the wear and tear on the bearings caused by radial forces.

These products use a magnetically biased, Hall-effect integrated circuit (IC) to sense rotary movement of the actuator over a set operating range. Rotation of the actuator changes the magnet’s position relative to the IC. The resulting flux density change is converted to a linear output. The IC, together with conditioning and protection circuitry, is sealed in an IP69K-qualified rugged package for durability in most harsh environments.

Eight operating ranges from 50° to 360° are tolerant to over-travel and allow use in most common applications. Low-voltage and high-voltage versions cover an input voltage range of 4,5 V to 30 V d.c. The sensors integrate reverse polarity and short circuit protection, and are tested for EMI/EMC to automotive grade. They come with industry-standard AMP termination, 32 mm mounting pitch, North American or European pinout styles, and a compact package.
