Position encoders and rotary sensors
We offer linear and rotary position encoders, absolute and incremental, based on our AMR (Anisotropic Magneto Resistive) and Hall-effect technologies. These technologies are not affected by dirt, oil, dust or other contaminants, or by changes in ambient lighting conditions. Outputs are either analog or digital. Various off the shelf and custom packaging options are available for our rotary sensors that provide rugged, low cost, non-contacting position feedback for demanding applications.

Hall Effect - Angular Encoder
How it works:
- A Hall Effect angular encoder consists of a ring that is magnetized in segments that alternate between north and south poling. The ring is attached to a rotating shaft.
- Hall Effect magnetic sensors are placed around the ring to detect its motion as the shaft rotates.
- Electronics on the PC Board demodulate the sensor signals and provide rotational displacement, speed, and direction information
