Product Description

Description

Securing hazardous industrial machinery requires robust safety interlocking. The Omron D4BL-2DRA heavy-duty guard lock safety-door switch provides reliable mechanical locking and 24 VDC solenoid release to prevent personnel from accessing dangerous areas until machinery has come to a complete stop. Featuring a robust aluminum die-cast housing, this Type 2 safety switch incorporates a built-in auxiliary release key and multiple contact configurations to interface seamlessly with safety monitoring relays and PLC systems.

Designed with a dual-conduit configuration, the D4BL-2DRA allows for flexible wiring layout and daisy-chaining within complex safety loops. The unit features built-in slow-action contacts for simultaneous door status monitoring and lock verification, ensuring high safety integrity in compliance with international machine safety standards.

Features

Mechanical Lock / Solenoid Release: Features a secure mechanical locking system with a 24 VDC solenoid mechanism for controlled, electrical release (power-to-unlock).
Dual Conduit Entry: Equipped with two G1/2 conduit outlets for straightforward cable routing and versatile installations.
Configurable Head Mounting: The switch head can be adjusted to four different directions (ships with right-side mounting) to fit varying machine configurations.
Integrated Auxiliary Release: Includes a built-in manual release key to unlock the guard in emergency situations or during power outages.
High Environmental Resilience: Rated to IP67 protection, offering durable performance against dust, oil, and liquid ingress.

Applications

Robotic work cells and automated assembly lanes
CNC machining centers and heavy metalworking equipment
Packaging machinery and conveyor system enclosures
High-inertia machinery requiring controlled access timing
