Siemens Solenoid Interlock Switch

The Siemens 3SE5 power to unlock solenoid interlock switch has a supply voltage rating of 24VDC. It has 2NC safety and 1NOauxiliary contacts. This has a separate actuator and an additional electromagnetic tumbler is designed for protective doors that have to remain closed while a machine is being shut down. An integrated auxiliary magnet in the switch keeps the door locked until a specific signal is received. A safety mechanism to prevent unwanted closing ensures that the NC contacts of the magnet never close even when the door is open. This switch can be released manually using an auxiliary release mechanism if, for example, access is required following a power failure or during installation.
Actuators must be purchased separately.
