Penny+Giles' dual-output rotary position sensor is intended for motorsport applications.

­A new high-precision dual-output rotary position sensor for motorsport applications was launched by Penny­+Giles at Autosport International 2009. The SRH280DP incorporates a factory-programmable Hall-effect sensor and has two outputs that can be programmed individually.

One signal can be used in a control function while the other is used for position monitoring or display modes for applications including steering (position monitoring) and suspension.

A range of parameters is available to configure the sensor to suit specific needs and achieve maximum performance. The measurement range and output can be specified in a clockwise or counterclockwise direction.

The sensor operates from either a 5 V dc regulated or 9-30 V dc unregulated power supply and has an overvoltage protection to 40 V dc. It can be supplied programmed with any one of 341 angles in the range 0-20° to 0-360° in 1° increments. It has a 12 bit resolution (0.025%) over the selected measuring range.

The SRH280DP sensor is available with analog (0.5 to 4.5 V dc) 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 counterclockwise on the second signal) and the output summed.

For use particularly in harsh motorsport environments, the sensor has been designed to achieve excellent shock and vibration resistance, says Penny+Giles. The shaft and body are totally sealed to IP68, for a high level of protection against the ingress of dust and water.

Also to fulfill motorsport requirements, it is available with a 2.4-mm (0.09-in) blade to suit Hewland gearboxes. It is fitted with a comolded four-core cable, spec 55A 24AWG cores with DR-25 outer jacket for compatibility with motorsport cable harnesses.

SRH280DP features electromagnetic compatibility immunity to 100 V/m and has a very low maximum output signal noise of less than 1 mV with no additional signal filtering needed on the output signal. Nonlinearity figure is ±0.4%.
