EUCHNER NM Design Type 1 Safety Limit Switches are used to protect personnel and equipment by monitoring the position of movable components. When positive mode mounted the NM safety switch actuator separates the positive opening safety contacts (in accordance with NFPA 79) providing the highest level of safety. Due to its sophisticated design, the entire group of NM switches complies with desire for machines with a more modern appearance. Two housing lengths provide for a greater choice in contact arrangements. High installation flexibility is gained with three cable entries (long housing version) and the ability to turn the actuator head in 90 degree increments.
