Contactless rotary position sensor with dual outputs

27 March 2009

Penny + Giles has introduced a contactless rotary position sensor with dual outputs The SRH280DP incorporates a factory programmable Hall effect sensor and its two outputs that can be programmed individually to provide reliable and accurate rotary position measurement in extreme industrial and off-highway environments. OEMs can specify the measurement range and output in a clockwise or anticlockwise direction, allowing one signal to be used in a control function while the other is used for position monitoring or display purposes.

The sensor operates from either a 5Vdc regulated or 9-30Vdc unregulated power supply and has an over-voltage protection to 40Vdc. It can be supplied programmed with any one of 341 different angles in the range 0-20 to 0-360 degrees in one degree increments and it has a 12 bit resolution (0.025%) over the selected measuring range.

For ease of configuration, SRH280DP is available with analogue (0.5 to 4.5Vdc) or digital (Pulse Width Modulated) signal output. The 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.
