Santest presents the rotary resolver RR series that is a rotation angle sensor utilizing of detecting the inductance caused by the change of magnetic permeability. The sensor section detects the rotation angle of the shaft in a non-contact manner, the angle signal is processed by the controller section and output. The rotor made of magnetic plate is fixed to the shaft and rotated synchronously.

The sensing part is very simple mechanical structure composed of  two PCBs and one rotor with magnetic plate, resulted in the low height. The coil is patterned on the multi-layered PCB. As it is harder to break comparing to a winding coil, RR series is robust to meet use in the harsh environment. Santest RR series has two types. One is a single turn absolute type, RR-14R and the other is 16 bit incremental one, RR-16Q. RR-14R simultaneously obtained parallel output and A / B / Z-phase pulse by connecting the RRC amplifier.
