Low-Profile, dual output rotary position sensor uses non-contact Hall-effect technology
25 March 2010
Penny + Giles has introduced the NRH280DP, a dual output rotary position sensor that uses non-contact programmable Hall-effect technology to provide reliable and accurate rotary measurement in extreme industrial and off-highway environments. This low-profile (6.5mm) sensor provides numerous parameter options, including measurement range, and clockwise or anticlockwise direction output. This flexibility enables the sensor to be configured so that one signal can be used in a control function while the other is used for position monitoring or display purposes.
Unlike conventional captive shaft rotary position sensors, the NRH280DP has a separate magnet assembly that activates the fully encapsulated Hall-effect sensor with a permissible air gap of between 2 and 7mm. This allows the sensor to be used in extreme environments that are subjected to high shock and vibration, or those subject to high-pressure wash-downs (IP69K protected).
To ease configuration, the sensor is available with analogue (0.5 to 4.5Vdc) or digital (Pulse Width Modulated) signal outputs as standard, but can also be factory programmed to offer 0.1 to 4.9Vdc output range, matching the equivalent signals from a potentiometer. Its two outputs can be used for error checking if they are set up to be opposed (clockwise on the first signal and anticlockwise on the second signal) and the output summed.
