3SE5322-0SE21
The Siemens SIRIUS 3SE5322 safety interlock switch features an electromagnetic locking design with a locking force of 1300N, supports 5-directional proximity, monitors both the actuator and electromagnet with 2NC+1NO contacts, and offers IP66/67 protection. The actuator is not included in the shipment and must be purchased separately.
Product Positioning
The SIRIUS 3SE5322-0SE21 is a Siemens electromagnetic interlocking safety switch with a locking force of 1300N. It can monitor the status of both the actuator and the electromagnet in a dual-circuit configuration. The actuator is not included in the main unit and must be purchased separately depending on the mechanism.
Core Product Advantages and Features
Electromagnetic locking mechanism
Driven by a 24VDC electromagnet, the locking mechanism has a locking force of 1300N, ensuring a secure lock when the protective door is closed, and meeting safety interlocking standards.
Supports 5-directional approach
The actuator can be triggered from 5 directions, with an operating speed range of 0.4~1.5m/s. It has high installation flexibility and can adapt to various security door configurations.
Dual-circuit slow-motion monitoring contacts
The actuator and electromagnet are each equipped with 2NC+1NO slow-acting contacts, which can monitor the door position and locking status separately, thereby improving the safety level.
IP66/67 plastic housing
The plastic housing has an IP66/67 protection rating and comes with three M20x1.5 spring-loaded cable inlets, making it suitable for long-term use in harsh industrial environments.
