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. The locking solenoid holds the guard closed until a stored energy hazard has dissipated. It can also prevent damage to a part in process due to an inadvertent machine shutdown. 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 robust metal safety switch STA is dimension-compatible with the proven EUCHNER safety switches TP and STP in plastic housing.

Note: 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.

TYPICAL APPLICATIONS INCLUDE

People protection (Stored energy hazards), Machine and production protection against: inadvertent machine shutdown and damaging machine and product, Machine tool, Presses, Grinders, Packaging, Material handling / storage retrieval systems, Plastic injection molding, Pharmaceutical, Food processing, Robot, Wood cutting
