Product Positioning
The SIRIUS 3SE5324-0SD21-1AE4 is a Siemens spring-locking safety interlock switch with a locking force of 1300N. It adopts the principle of automatic locking when power is off and releases only when the electromagnet is energized. It is suitable for high-security door applications.
Core Product Advantages and Features
Spring locking mechanism
It generates a 1300N locking force with spring force, and automatically maintains the locked state when the power is off, which complies with the power failure protection (Ruhestromprinzip) safety principle.
24VDC electromagnet release
It requires 24VDC power to release the lock, making it suitable for high-security protective door applications that require locking upon power failure.
Safety circuit auxiliary contact
Equipped with a slow-acting safety auxiliary contact, rated current 1.5A (AC-15/DC-13, 24V), it can be connected to a safety relay circuit.
IP66/67 plastic housing
The plastic housing has an IP66/67 protection rating, and the metal threaded cable inlet is suitable for long-term use in dusty and watery environments.
