The Siemens safety position switch with tumbler approaches spring-locked escape release from the rear and auxiliary release on front magnet voltage 24 V DC monitoring . They ensure that protective doors, covers or protective flaps/grilles are kept closed, for as long as a hazardous state exists.
The actuator heads with screw less mounting can be rotated by 4x90 degrees. Five directions of approach are possible for the actuator, one of which is from the front. The contact blocks ensure an extremely high contact stability and can only be switched with separately coded actuators that guarantee greater protection against manipulation. LEDs conveniently indicate the current state of the device. The devices have worldwide approval (IEC, UL). With the corresponding switch configuration, the highest safety requirements specified by PL e or SIL 3 can be met. The 3SF1 series with direct connection to the AS-Interface bus system completes the portfolio.
