APEM expanded its range of proportional thumbwheels with a new, friction hold version. This new patented technology allows for ultra-precise movement while allowing the user to hold the selection in a set position.
The HR series uses proven non-contacting Hall effect sensor technology, independent from the friction mechanism, providing a smooth and precise linear voltage output that does not degrade over time. It is ideal in applications that include panel-mount and joystick integration, as well as agricultural machinery, material handling equipment and off-road vehicles.
The thumbwheels come in two versions: one with 11 detents along the travel (1 at centre and 5 on each side) and another with a centre detent, smooth movement on each side and providing a feel of friction hold without detents. Providing IP68 sealing and a mechanical life of 100 000 cycles, they are available in a selection of colours as well as models with backlighting.
