Description

Designed to secure heavy-duty machinery safeguarding systems, the D4BL-2DRG heavy-duty guard lock safety-door switch provides mechanical locking and solenoid release to protect personnel from hazardous machine areas. This Type 2 safety switch incorporates a high-durability die-cast aluminum housing, making it highly suitable for demanding industrial automation setups that require strict safety compliance.

Operating with a 24 VDC solenoid lock mechanism, the switch remains securely locked until a release signal is received, preventing accidental entry during dangerous cycles. It is configured with a 2-conduit G1/2 outlet design and a highly adaptable head supporting four distinct mounting orientations, streamlining physical integration on various safety fence profiles.

Features

  • Rugged metal die-cast aluminum housing for harsh industrial environments.
  • Secure solenoid lock with mechanical release function for fail-safe door control.
  • Built-in switch assembly containing 2NC (slow-action) and 1NC (slow-action) contacts.
  • Adjustable head mount allows selection of four different installation directions.
  • IP67 degree of protection against ingress of dust and liquids.
  • Type 2 interlock device classified as low-level coded according to EN ISO 14119.

Applications

  • Automotive manufacturing and assembly lines.
  • Robotic cell enclosures and high-risk work zones.
  • Heavy machining, milling, and metal-stamping equipment guarding.
  • High-inertia industrial machinery that requires delay-to-access control.

Installation Guidelines

  • Ensure the operation key is aligned properly with the key slot before securing the main switch body.
  • Do not use the safety switch as a mechanical stop for the door; physical door stoppers must be installed independently.
  • Provide a stable, regulated 24 VDC supply voltage to the solenoid coil to prevent chatter or incomplete unlocking.
  • Mount the switch and its wiring in accordance with EN ISO 14119 specifications to preserve the intended safety integrity level (SIL/PL).

Compliance and Certifications

  • EN ISO 14119
  • EN 60947-5-1

FAQ

What is the locking and unlocking mechanism of the D4BL-2DRG?

The D4BL-2DRG features a solenoid lock and mechanical release. The switch mechanically locks the door when closed, and releases only when the 24 VDC solenoid is energized.

Can the mounting head direction of the switch be adjusted?

Yes, the switch head can be rotated to allow mounting in four different directions. By default, it is shipped with right-side mounting.

What contact configurations are built into this Omron switch?

It features a built-in switch layout of 2NC (slow-action) plus 1NC (slow-action) contacts, dedicated to door status detection and lock monitoring.

What is the environmental protection rating of the D4BL-2DRG?

The switch has an IP67 degree of protection (conforming to EN60947-5-1), providing reliable protection against dust and liquid ingress in industrial environments.
