Control Devices introduce the SRH500 rotary position sensor
Penny + Giles and Control Devices have introduced a rugged and configurable rotary sensor, the SRH500P. The factory programmable sensor can be used in extreme environments and provides a wide selection of parameters for configuration to suit individual needs.
Using non-contact Hall effect technology, the rotary sensor can operate in high dither vibration conditions without causing any deterioration of the sensing element. The rotary sensor is resistant to shock and vibration, which makes it ideal for many position monitoring applications on off-highway vehicles. These include:
- Steering position
- Suspension position
- Lift system position
The rotary sensor operates from either a 5Vdc regulated or 9-30Vdc unregulated power supply and can be programmed with any one of the 341 different angles, from 20 degrees up to 360 degrees in one degree increments. The rotary sensor has a 12 bit resolution (0.025%). For ease of configuration, it is available with single or dual redundant analogue (0.5 to 4.5Vdc) or digital (PWM) outputs.
The measurement range and output can be specified in a clockwise or anticlockwise direction. A dual output version can be set up to have independent measurement ranges for each output.
The SRH500P rotary sensor is easy to install and has a very low maximum output signal noise of 1 mV rms. It is mechanically interchangeable with the Penny + Giles SRS880 and SRH880 rotary sensors, enabling existing users to upgrade to a higher level of control.
The SRH500P rotary sensor is available in marine grade cast aluminum with an 88mm diameter flange and 12mm diameter shaft. When specified with cable option D, the rotary sensor is sealed to IP69K for increased protection in harsh environments, which prevents ingress against dust, water and pressure jets. The SRH500P can withstand high temperature applications and when powered at 5Vdc, it can operate reliably in the temperature range of -40 to +140°C.
For added customisation, the rotary sensor is available with four choices of electrical connection such as:
- Gland only
- Gland and cable
- Gland cable and IP69K connector
- M12 connector
Larger volume users can also be offered for non-linear and switched outputs, clamp voltage levels, mixed analogue and digital outputs and different output phasing to shaft position.
