RLB rotary miniature PCB level incremental magnetic encoder

More Views

RLB is a PCB level incremental encoder sensor system consisting of a PCB sensor and a magnetised ring. It has been designed for embedded motion control applications as a position control loop feedback element in space constraint applications.

 

The information carrier is a periodically magnetised scale with 2 mm pole length. Radial or axial reading of the ring is possible. The readhead can ride at up to 0.4 mm from the ring's surface.

 

State of the art position sensing assures highly repeatable position measurement under wide installation tolerances and temperature ranges. The position information is output in incremental quadrature format with the option of a periodic reference mark (every pole).

 

The maximum speed depends on the chosen resolution and minimum edge separation time, to 4 m/s at 1 µm and to 40 m/s at 10 μm.
