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).
