Siemens | 3SE5322-0SB21 | Solenoid Interlock

Solenoid interlock switch with a separate actuator and additional electromagnetic tumbler designed for protective doors that must remain closed while a machine is being shut down. An integrated auxiliary magnet in the switch keeps the door locked until a specific signal has been received. A safety mechanism to prevent unwanted closing ensures that the NC contacts of the magnet never close even when the door is open. The switch can be released manually using an auxiliary release mechanism if, for example, access is required following a power failure or during installation. It features an integrated solenoid interlocking with 24V coil voltage, six switching contacts, and separate position sensing for the magnet and the protective door.
