GTIN Standard 4536854898587

Technical Overview

The Omron D4NL-1AFG-B is a highly reliable power-to-lock safety guard-door switch designed for automated industrial applications. It uses a 24 VDC solenoid locking mechanism to deliver a robust 1300 N minimum holding force, ensuring machinery doors remain locked during hazardous operations. The switch features 1NC/1NO contacts for door detection and 1NC/1NO contacts for lock monitoring. Housed in a durable plastic enclosure with an IP67 rating and a PG13.5 conduit entry, it withstands demanding environments while providing clear status updates via an orange LED indicator.

Key Features

  • Power-to-lock, mechanical release mechanism (24 VDC solenoid)
  • Minimum key holding force of 1,300 N
  • 1NC/1NO (door open/closed detection) + 1NC/1NO (lock monitor) slow-action contacts
  • IP67 degree of protection for resistance against dust and water
  • Orange LED visual status indicator (10 to 115 VAC/VDC)
  • PG13.5 conduit entry with standard plastic head
  • Mechanical durability rated for a minimum of 1,000,000 operations
  • Compliant with EN ISO 14119 Type 2 low level coded standard

Industrial Applications

1. Automated Robotic Cell Perimeters

Secures the physical access doors of an automated robotic assembly or welding cell.

Problem Solved

Prevents unauthorized entry while heavy robotic arms are in motion. The 1300 N holding force ensures the door cannot be forced open until the controller issues a 24VDC unlock signal.

2. CNC Machining Center Enclosures

Interlocks the main sliding operator door on CNC milling machines and lathes.

Problem Solved

Maintains a secure lock during high-speed cutting cycles to protect operators from moving parts and flying debris, while the IP67-rated enclosure resists degradation from continuous machine coolant spray.

3. Industrial Conveyor Access Gates

Provides safety locking for maintenance gates along high-throughput material handling conveyor systems.

Problem Solved

Ensures that power to heavy-duty conveyor motors is safely monitored via the dual 1NC/1NO contact circuits, preventing the gate from being opened until motion has completely ceased.
