More Views

RLC2HD is a PCB level incremental encoder sensor system consisting of a PCB sensor and magnetic scale or 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 a pole length of 2 mm. Radial or axial reading of the ring is possible.


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 traverse velocity depends on the chosen resolution and minimum edge separation time, to 7.5 m/s at 1 µm and to 75 m/s at approx. 10 μm.


The RLC2HD is a moisture sensitive device. It should be soldered immediately after the transportation packaging has been opened. If not, baking procedure should be performed.
