TP Series Solenoid Locking Safety Switch


EUCHNER TP 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 passed. 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 and redundancy to guarantee that they fail to a safe state. The TP is a narrow profile thermoplastic housing with many variations to meet a variety of different needs.
