Omron D4BL-2DRG D4BL Series Guard Lock Safety-Door Switch

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
