D4BL-2DRA | Omron | Interrupteur de porte de sécurité à verrouillage

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.
