Direction Sensors Improve Motor Performance

Description

SNG-Q series quadrature speed and direction sensors for use in motors in heavy-duty equipment use Hall-effect technology to provide a non-contact method to measure both the rotational speed and direction of a ferrous material toothed gear mounted to an AC induction motor shaft.

 

Industrial equipment applications include vehicle speed, vehicle motion, raising a machine’s lifting fork, wheel-speed direction, and traction and braking control.

 

The SNG-Q series sensors can be used to help control power regulation of hybrid electric transmissions as well as hybrid engines in heavy-duty trucks, buses, and agricultural vehicles. In addition, they can help control the speed and position of escalators and elevators.

 

The new sensors offer engineers a wide operating temperature range (-40 to 150°C), electrical noise radiated immunity (rated to 100V/m) and IP69K environmental sealing to provide flexibility of use in the application. The supply voltage ranges from 4.5V to 26V.

 

Honeywell offers both 35 mm and 45 mm housing lengths for the SNG-Q series sensors.
