Contactless rotary position sensor with dual outputs
Penny + Giles has announced the availability of a new low profile rotary position sensor with dual output channels. The SRH280DP, which incorporates a factory programmable Hall effect sensor, has two outputs that can be programmed independently. It provides reliable and accurate rotary position measurement in extreme environments and allows users to improve the safety and integrity of their control systems.
The sensor operates from either a 5Vdc regulated or 9-30Vdc unregulated power supply. 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.
The sensor has been especially designed to work in harsh environments and has excellent shock and vibration resistance. The shaft and body are totally sealed to IP68, for a high level of protection against the ingress of dust and water. When operated at 5Vdc it has a superior temperature rating to +140ºC and a temperature stability of less than ±30ppm/ºC.
The sensor body has a crush-proof 28mm mounting flange, with a body depth of only 18.1mm from the mounting face – 22% smaller than it’s nearest rival.
