Rotary Solenoids with Return Spring

RSR28/17-SL Series

Return-by-spring type rotary solenoid.
Because there is no axial stroke of the center shaft during the rotation like the conventional rotary solenoid, it will free you from displacement of the load attached.
It is suitable for high-precision usage.
Equipped with a stopper in standard and available in various operating angles.
The end stops are equipped with buffer material to reduce impact noise.
