Product Overview
The Omron D4NL-1AFG-B is a guard-lock safety-door switch from the D4NL series, manufactured by Omron Corporation. Hengyixin Automation stocks this safety device in Xiamen and ships within 3-5 business days; safety-rated components ship with a batch-trace certificate.
The switch locks a guard door with a power-to-lock 24 VDC solenoid that delivers 1,300 N minimum holding force. Two independent contact sets monitor the door: 1NC/1NO slow-action for door position and 1NC/1NO slow-action for lock status. The orange LED indicator at 10-115 VAC/VDC shows the lock state.
Mechanical durability is rated for 1,000,000 operations. Direct opening travel is 10 mm min at 60 N min direct opening force per EN 60947-5-1. The PG13.5 conduit entry takes a standard cable gland. The D4NS-1AF is the non-locking tongue switch for lighter guarding; the D4BL-2CRA is the metal-head lock switch for heavy industrial doors.

- Voltage: 24 VDC
Best-Fit Applications
- Guard locking on a CNC milling machine sliding door where the door must stay locked during high-speed spindle rotation
- Access interlock on a robotic welding cell perimeter where the 1,300 N holding force resists forced entry during arc-flash cycles
- Spare replacement on a packaging machine safety circuit where the existing D4NL-1AFG-B has reached the end of its 1,000,000-operation mechanical life
Buying Checklist
- Pick the D4NL-1AFG-B for a power-to-lock plastic guard-lock switch with 1,300 N holding force and a 24 VDC solenoid on a PG13.5 conduit.
- Pick the D4NS-1AF instead when the door only needs a non-locking tongue interlock at a lower cost.
- Pick the D4BL-2CRA instead when the cabinet needs a metal-head solenoid-lock switch for heavy industrial doors.

FAQ for D4NL-1AFG-B
What is the Omron D4NL-1AFG-B used for?
It is a guard-lock safety-door switch for machine guarding on robotic cells, CNC enclosures, and conveyor access gates. The 24 VDC power-to-lock solenoid holds the door shut until the safety controller explicitly releases it.
D4NL-1AFG-B vs D4NS-1AF - what is the difference?
The D4NL-1AFG-B locks the door with a 24 VDC solenoid at 1,300 N. The D4NS-1AF is a non-locking tongue-operated interlock switch with no holding force, only a position signal. Pick the D4NL when the door must stay locked while the machine is in a hazardous state.
What is the IP rating of the D4NL-1AFG-B?
IP67 on the housing. The PG13.5 conduit entry needs a separate IP67-rated cable gland for the overall enclosure to remain IP67 in service. Operating temperature is -10 to +55 C.
Which operation key fits the D4NL-1AFG-B?
The D4DS-K2 is the standard vertical-mount operation key. The D4DS-K1 is horizontal-mount; D4DS-K3 and D4DS-K5 are adjustable-mount keys. All four keys are cross-compatible with the D4NL head.
