Position sensor with J1939 capability

The PST-360 from Piher Sensors & Controls (Spain) is a contactless position/angle sensor. It combines a through-shaft design with 360º absolute position feedback in a 14-mm or 17-mm shaft design.

Key features include through hole sensing where the shaft passes directly through the sensor, high accuracy absolute position feedback over 360°, and a true non-contacting sensing element. The sensor incorporates a proprietary ring magnet with hall chip for the sensor element. This combination does not rely on gears or other rotating parts, maximizing robustness and sensing accuracy. The proprietary design provides a streamlined sensor with only one moving part along with electronics designed for harsh environments. The sensor features CAN J1939 with up to 14 bits.

Measuring 9,8 mm with a body diameter of 37 mm and 50 mm mounting hole spacing, engineers can now integrate a fully featured rotary sensor directly on their existing shafts without the packaging issues that typically accompany encoders or other through shaft sensing devices, said the company. The exceptionally low profile fits in places that were previously too narrow for pre-packaged rotary sensors. The standard models feature a 14-mm or 17-mm diameter double flatted shaft design. Custom rotor configurations are available from the company to adapt existing OEM (original equipment manufacturer) shafts to the regular PST-360 sensor.

The product uses a patented Hall effect technology to enable true non-contacting through-hole shaft sensing with only one moving part –the proprietary ring magnet. This design is robust with fully encapsulated electronics surrounding the durable ring magnet. It has no sensitivity to dust or dirt and can tolerant high vibration cycles as the ring magnet never comes into contact with the sensing electronics. The device is provides high accuracy position feedback at power on.

With it’s integrated redundancy, this position/angle sensor is suited for use in a range of off-highway, construction, agriculture equipment steer-by-wire applications. It can be adapted to fit marine outboard steering and throttle control, sport, and exercise equipment, wind indicators, automation equipment, and medical devices. A range of popular mating connectors is available as optional features.
