Accuracy is key for rotary hollow shaft position sensor
Published: 11 January 2012 - Heather Ramsden
Variohm’s EuroSensor, BEI Duncan 8360 series high accuracy rotary position sensors feature non-contact potentiometric technology with continuous rotation, electrical angles up to 360 degrees and dual redundant analogue outputs in a compact and robust IP65 sealed package that includes a splined through-hole design for direct shaft mounting.
The 8360 will suit both harsh environment and safety critical angle measurement applications where high reliability, long life and exceptional durability are important design considerations. For use in agricultural and construction machinery, medical equipment, industrial automation and process control, typical uses will be steering angle, crane boom angle, throttle range and traction control feedback.
With an overall thickness of less than 16mm and nominal footprint around 85mm x 105mm, the 8360 series sensor can be mounted in space restricted areas where the through-hole will directly interface with a 12-tooth splined shaft from 16mm to 20mm in diameter. For straightforward installation, the sensor has four face mount bush inserts and is supplied complete with a 200mm cable assembly with a 6-pin AMP connector. The robust and durable angle sensor has high shock and vibration resilience, overvoltage, short circuit and ESD protection as well as magnetic shielding.
