Hollow-shaft precision potentiometer
Spectrum Sensors

The newest line of hollow shaft position sensors by Spectrum Sensors & Controls take up less space, have infinite resolution, the longest life and excellent output smoothness. These sensors feature anodized aluminum, thermo plastic design with diameters ranging from 0.570" (14.48mm) to 1.437" (36.5mm) and a rotational life of 5 to 50 million cycles minimum.

The hollow shaft position sensor has an electrical angle of 340°, an independent linearity range of ±0.5% to ±1.0%, power ratings of 0.5W to 2W at 70°C and a maximum output smoothness of 0.1%. Additionally, these position sensors feature a resistance range of 1KΩ ~20KΩ ±10%, 360° continuous rotation, and require no wiper installation or phasing.
