Omron Solenoid Interlock Switch D4BL Series Power to Unlock 24V DC Coil Current 300mA Model

Omron D4BL-1CRA solenoid interlock switch is a safety device specialized for industrial automation and machine safety where door access must be strictly controlled. This model uses power to unlock the mechanism featuring a 24V DC coil consuming approximately 300mA current, ensuring controlled and safe operation in automated cells and guarded machine doors.

The switch has a die-cast aluminium metal housing rated IP67 for environmental protection and mechanical robustness. It includes both normally closed (NC) and normally open (NO) contacts to monitor door status and lock condition effectively.

Designed with versatility, it accepts 1/2 inch NPT conduit entries both horizontally and vertically to enable flexible cable routing. The unit uses screw terminals for wiring securing standard torque values, supporting safe and stable installation.

This interlock switch operates reliably with a contact AC voltage rating of 240V suitable for control and signalling circuits, making it adaptable for integration with safety relay systems and monitored access control on machinery such as CNC equipment, presses, and cutting tools.

The mechanical lock remains engaged during power loss until manually released, ensuring safety during hazardous conditions. The device meets key safety certifications including UL, CCC, and CSA standards and is manufactured in Japan guaranteeing quality and durability.
