Siemens Solenoid Interlock Switch, 24V DC, M20 - 3SE5 Series - 3SE5322-0SD21


Need a way to securely lock guards or gates during dangerous operations? Use this solenoid interlock switch from Siemens. It has a separate actuator and additional magnetic tumbler so that protective doors don't open during hazardous processes. A safety mechanism also prevents unwanted guard or door closures by keeping the NC (normally closed) magnet contacts open even when a guard or door is open. You can deactivate the switch manually using the auxiliary release mechanism if needed – for example. during power failures or installation. This device is suitable for use with applications using circular saw blades or where restricted entry is required to dangerous areas, such as high-temperature sites.

• IP67 (ingress protection) rating means the unit is completely protected from dust and can withstand water submersion for up to 30 minutes
• An LED (light-emitting diode) display indicates the status of the switch and door as a visual safety measure
• Additional lock, escape and emergency release mechanisms for versatile use

What's the difference between power-to-lock and power-to-release switches?


Power-to-lock switches unlock when the power supply is turned off. Power-to-release switches stay locked even during power failures. That's why checking for a manual unlocking mechanism is important when selecting a solenoid interlock switch.
