Hall-effect angle sensors with shaft

The wide range of Elen angle sensors perfectly meets the requirements of manufacturers of agricultural machinery, industrial vehicles and their subassemblies. Elen’s angular sensors detect rotary motion through a contactless Hall element, providing a proportional output with respect to the absolute position. The programmable card, in addition to the straightforward and solidly-built mechanism, guarantee a reliable, accurate and repeatable signal which can be configured by the customer. This is the reason why Elen’s angular sensors are the most reliable and flexible solution for maximum precision and resistance to harsh environmental conditions, for example on steering axles, articulated arms mechanisms, accelerator pedals and active suspension systems.

CONSTRUCTIONS FEATURES

1. PROGRAMMABLE CIRCUIT BOARD
A Hall sensor intercepts the magnetic field generated by a magnet which rotates jointly with the shaft, generating an output signal which is proportionate to and in line with the rotation angle or a square wave with a duty cycle proportionate to the rotation angle. The programmable circuit board guarantees a wide range of output configurations and a reliable, accurate and repeatable signal.

2. MATERIALS
The anodized aluminum case guarantees protection against corrosion provoked by external elements; ensures maximum resistance to impact and vibrations. The resin guarantees impermeability from external elements.

3. INDEPENDENT CIRCUITS
A separate module having no contact with the sensor, thus making the product resistant to mechanical wear and tear, typical of potentiometric solutions. The protection diaphragm guarantees protection against infiltrations from external elements and prevents mechanical shocks to the shaft from damaging the circuit board or altering the signal.

4. SHAFT UNIT
A separate module having no contact with the sensor, thus making the product resistant to mechanical wear and tear, typical of potentiometric solutions. The protection diaphragm guarantees protection against infiltrations from external elements and prevents mechanical shocks to the shaft from damaging the circuit board or altering the signal.
