NZ.VZ Design Type 2 Safety Switches

EUCHNER Design Type 2 Safety Switches are used to protect personnel by monitoring and interrupting the safety circuit depending on the position of the machine guard. To meet current worldwide standards, safety interlock components cannot be easily bypassed. These switches have positive opening contacts (in accordance to NFPA 79) and redundancy to guarantee that they fail to a safe state. The NZ features a die cast aluminum housing and variety of actuators. A solenoid locking version is offered to hold the guard closed until a stored energy hazard has passed. It can also prevent damage to parts in process due to an inadvertent machine shutdown.

Note: A design type 2 safety switch has an actuator that is separate from the switch body. The two must be combined or separated for switch operation.
