Guard lock safety-door switch with 3NC + 2NC contacts and a 24VDC solenoid. Features a 1300N holding force, IP67 rating, and resin head for reliable industrial safety.
The OMRON D4SL-N4HFG-D is a heavy-duty, general-purpose guard lock safety-door switch designed to effectively secure hazardous industrial environments. It provides a robust minimum holding force of 1300 N and employs a power-to-lock (solenoid lock) mechanism with mechanical release to strictly prevent access while machinery is active. Equipped with a comprehensive 3NC + 2NC contact configuration, it easily interfaces with safety controllers and PLCs using a 24VDC control voltage. The switch is housed in a highly durable plastic and resin enclosure rated for IP67 and UL Type 4X protection, making it resilient against extreme industrial conditions, dust, and water ingress. Installation is simplified through an integrated M20 conduit outlet and easy-access terminal block wiring, complemented by a built-in orange LED indicator for rapid visual status verification.

Securing access doors to automated robotic welding or assembly cells to strictly control human entry.
Prevents operators from physically opening the cell door while the robot is active by utilizing the 1300N holding force and power-to-lock logic, eliminating mid-cycle interruptions and ensuring personnel safety.
Monitoring and locking the primary access panels and doors of heavy-duty CNC milling and turning machines.
Protects operators from high-speed rotating parts and flying debris by preventing door opening during operations. The IP67 and UL Type 4X ratings ensure the switch survives extreme exposure to coolant splashes and metallic dust.
Securing the perimeter safety gates on high-speed automated packaging and palletizing machinery.
Ensures fail-safe machine halting if an unauthorized override occurs, utilizing the 3NC + 2NC safety contact layout for redundant stop signaling and direct integration with safety PLCs using a 24VDC controller output.
