Safety interlocks

Elobau Sensor Technology Inc. announces that it now has a complete line of interlock switches for safety applications for the automation and specialty machine market. These 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 interlocks include solenoid locking, narrow metal body housing and metal actuating head, rotatable actuator head with top and side entry, actuator insertion funnel that increases entry area, straight, bent, and hinged actuators (including over-travel).
