Description

RH Hall Effect contactless rotary position sensors are designed around a unique two-part assembly consisting of a sealed electronics module and separate operating shaft. When rotated, the shaft accurately measures up to 360° of angular position without mechanical contact with the face of the sensing module (contactless). The sealed design, the module is IP67 and the ball-race shaft bearings IP64, makes it suitable in measurement applications where fluid, debris and vibration are a consideration.

The sensor operates from either a 5Vdc regulated or 8 to 30Vdc unregulated supply and the output signal is 0.5V - 4.5V or 0V to 4V with a 12-bit resolution (0.08°). The operating temperature is 130°C and every RH sensor module is heat cycled prior to final calibration to ensure output signal stability when operated at elevated temperatures. The sensors electrical angle and output signal direction, clockwise or anticlockwise is specified by the customer.

The RH module and shaft design offers a versatile and reliable position sensing solution with a multitude of mounting options. RH models are available with the rotating shaft set within twin 'long life' stainless steel ball-race bearings for low-force shaft operation. Additionally, the compact electronics housing is designed for the easy fitting of a Raychem heat shrink cable boot.
