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

FAQ
What is the locking and release mechanism of the Omron D4BL-2DRA?
The D4BL-2DRA uses a mechanical lock mechanism that automatically secures the guard when closed. It requires an active 24 VDC solenoid signal to release the lock (power-to-unlock).
Can the switch head orientation be adjusted?
Yes, the switch head can be rotated and mounted in four different directions (90-degree increments) to accommodate different guard door entry configurations. It is shipped from the factory with right-side mounting.
What kind of conduit entries does this safety switch have?
The device features two G1/2 conduit outlets, enabling versatile wiring pathways and simplified daisy-chain installation.
Is there a manual override for the lock?
Yes, the switch features a built-in auxiliary release key that allows authorized personnel to manually unlock the guard in the event of a power loss or emergency.
