Low-profile rotary position sensor features dual outputs

Penny & Giles is launching a new low-profile, contactless 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 enables users to improve the safety and integrity of control systems.

Operating from either a 5V DC regulated or 9-30V DC unregulated power supply, the sensor 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 has a 12-bit resolution (0.025 per cent) over the selected measuring range.

For ease of configuration, the SRH280DP is available with analogue (0.5-4.5V DC) or digital (pulse width modulated, PWM) 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.

This contactless sensor has been designed to work in harsh environments and benefits from excellent shock and vibration resistance. The shaft and body are sealed to IP68 for protection against the ingress of dust and water. When operated at 5V DC it is claimed to have a superior temperature rating to +140degC and a temperature stability of less than +/-30ppm/degC.

The sensor body has a crush-proof 28mm mounting flange, with a body depth of only 18.1mm from the mounting face - which is said to be 22 per cent smaller than its nearest rival.
