Penny + Giles will be launching the SRH280DP rotary position sensor with dual outputs at Autosport International 2009.

The sensor, which incorporates a factory programmable Hall effect sensor, has two outputs that can be programmed individually.

The company said that it provides accurate rotary position measurement in extreme environments and allows motor sport users to improve the safety and integrity of control systems.

For example, one signal can be used in a control function while the other is used for position monitoring or display purposes, for applications such as steering position monitoring and suspension.

Users can choose from a range of parameters to best configure the sensor to suit specific needs and achieve maximum performance.

Users can specify the measurement range and output in a clockwise or anticlockwise direction.

The sensor operates from either a 5V DC regulated or 9-30V DC unregulated power supply and has an over-voltage protection to 40V DC.

It can be supplied programmed with any one of 341 different angles in the range 0-20 to 0-360deg in one degree increments, and has a 12-bit resolution (0.025 per cent) over the selected measuring range.

For ease of configuration, SRH280DP is available with analogue (0.5 to 4.5V 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 anticlockwise on the second signal) and the output summed.

The sensor has been designed to work in harsh motor sport 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.

It has a temperature rating to +140C when operated at 5V DC and a temperature stability of less than +/-50ppm/C.

The sensor body has a crush-proof 28mm mounting flange.

SRH280DP features electro magnetic compatibility (EMC) immunity to 100V/m and has a very low maximum output signal noise of less than 1mV.

This means that no additional signal filtering is required on the output signal.

It also has a non-linearity of +/-0.4 per cent.

The sensor body depth is 18.1mm from the mounting face, which allows the sensor to be fitted into tight spaces.

SRH280DP has a one-piece spring shaft design (or D shaft option) to suit motor sport applications and it is also available with a 2.4mm blade to suit Hewland gearboxes.

It is fitted with a co-moulded four-core cable, spec 55A 24AWG cores with DR-25 outer jacket, compatible with motor sport cable harnesses.
