XFSC-XFRZ Position Limit Switches

Cross position limit switches designed for controlling the movement of overhead travelling cranes, hoists and complex machine tools. X-FSC features cross or “T” rods which may move to 3 or 4 maintained positions, while the X-FRZ series features a single rod or a rod with roller with spring return movements. X-FSC and X-FRZ position limit switches have both enclosure and head made of thermoplastic material. (nylon reinforced with fiberglass)
