The plastic-encapsulated safety switches of design NM are used for monitoring the position of safety doors and moving machine components. \nEvery user can thus employ the optimum actuating element for his/her application. The easy adjustability of the actuator heads in 4 approach directions permits maximum flexibility. Two basic housings are available with up to 3 switching contacts. The compact design, as well as the option of any installation orientation, means that these switches can be integrated with all automation and assembly fields. Safety switch NM.AV/NM.AL, hinged actuator as solid shaft, short housing. The hinged actuator is a solid 75mm shaft and has a cable entry of M16 x 1.5.
