CS series is a switching sensor adopting magneto-inductive principle without mechanical contact. Combined with CSC controller, forward/backward limit points are output; furthermore the both points can be individually adjusted by trimmer integrated in the controller. As a sensor rod is completely sealed, the sensor can be installed inside hydraulic/pneumatic cylinders. Integrated coils inside sensor rod detect locations of movable magnet utilizing a change of inductance according to magneto-inductive principle. Since CS series has no mechanical contact as seen in coventional lead switches and also has no mechanical wear-out, a long life and reliability can be expected. Moreover the remote adjustment for detecting points is possible because switching points can be changed by trimmer in the controller.
