Siemens 3SE5 Series Solenoid Interlock Switch with Power to Lock Actuator Included 230V AC 3.5W 3SE5322-0SB23

Siemens 3SE5322-0SB23 Solenoid Interlock Switch, part of the 3SE5 Series, is engineered for industrial and automation safety applications requiring power to lock actuators. Operating at a supply voltage of 230V AC with a power consumption of 3.5W, this switch ensures the protective doors remain securely locked during machine shutdowns to prevent unauthorized access and enhance workplace safety.

Constructed with a robust plastic housing, the switch offers IP66 and IP67 ingress protection, making it suitable for harsh environmental conditions. It integrates a safety contact of 1 normally open (NO) type and features an M20 conduit entry with screw terminals for reliable electrical connections. Its dimensions - 184.1mm depth, 54mm length, and 43.8mm width - allow for versatile installation in various industrial settings.

The switch includes a manually operable auxiliary release mechanism to permit access in the event of power failures or during maintenance installations. The actuator heads are rotatable in 90° increments, enabling multiple directions of approach to suit different machine designs. Optical status monitoring enhances operational visibility.

Certified to CSA, VDE, and UL standards and offering protection up to Cat 4 (EN 954-1) and SIL 3 IEC 62061, this interlock switch complies with stringent safety requirements. Manufactured in Germany, it guarantees industrial-grade quality and reliability for demanding automation environments.

The switch incorporates an integrated electromagnetic tumbler for high locking force. Supports multiple release mechanisms including auxiliary, lock, escape, and emergency releases for flexible application. Designed to prevent unwanted door closing with a safety mechanism ensuring NC contacts never close when door is open.

Included 2 x 3 contact blocks for magnet and actuator monitoring.

This Solenoid Interlock Switch is ideal for use in industrial automation, manufacturing, HVAC safety controls, and electrical cabinet security applications. Safeguard your machinery and maintain compliance with industrial safety standards by deploying this Siemens 3SE5322-0SB23 safety interlock solution.
