The RTP series hall-effect rotary position sensors provide non-contact sensing in harsh transportation and industrial applications at a competitive cost. The RTP series takes non-contact sensing to the next level by separating the magnet from the sensor body. The absence of the actuator shaft removes the wear and tear on the bearings caused by radial forces. A choice of a bare or a housed magnet is available.

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 Vdc to 30 Vdc.
