Sensor offers accurate angular measurement

The Sensing and Control business of Honeywell has introduced the RPN Series rotary position sensor for angular position sensing in surface transportation and off-road vehicle applications.

The Sensing and Control business of Honeywell has introduced the RPN Series rotary position sensor for angular position sensing in surface transportation and off-road vehicle applications where high accuracy, environmental protection and freedom from wear-out failure mechanisms are important.

Using solid-state Hall-effect technology, the RPN Series offers reliability, long service life and low torque actuation.

Its rugged housing and IP67 sealing ensure durability in harsh operating environments while features such as integrated reverse polarity, short circuit and EMC protection conform to industry standards.

The sensor has a 90deg measuring range with 360deg allowable rotation.

This gives a wide operating angle tolerant to overtravel.

RPN Series rotary position sensors use a magnetically biased Hall-effect IC to accurately sense angular movement of the actuator shaft.

The IC, together with conditioning and protection circuitry and two permanent magnets, is sealed in a rugged package with integral connector.

Rotation of the actuator shaft changes the Hall-effect IC's position relative to the magnets.

This results in a change in the flux density detected by the Hall effect IC as the shaft is rotated.

The output of the IC is then converted to a linear output over 90deg of travel.

Supply voltage is 10 to 30V DC and temperature range is -25 to +85C.

The measuring range is +/-45deg and mechanical angle of rotation is 360deg.
