Rotary position sensors

The RFC4800 Series of touchless rotary angle sensors provide absolute rotary position. The sensors use a magnetic pickup for a touchless measurement range of 0 to 360°. Key specifications include 4 to 20-mA current output, sealed to the IP67 standard, 12-bit resolution, and independent linearity of ±0.5 %.

Switch characteristics include two pnp positive switched outputs, switching-zone width is user programmable, 50 years data retention, edge width of switch function is ›0.1° and accuracy of switch edges is ±1°. A magnetic marker mounts to a shaft on the application up to 25 mm from sensor.

The sensors withstand shock and vibration up to 100 g/20 g and operate at –40 to 85°C.
