Datasheet - D4SL-N4DFA

Omron D4SL Series Solenoid Interlock Switch, 4.8W Power Consumption, IP67 - D4SL-N4DFA

This solenoid interlock switch is a Compact safety device designed to monitor and lock access to hazardous areas in industrial automation and machinery. It combines an interlocking mechanism with electrical monitoring contacts and a solenoid-driven release, suitable for panel or frame mounting where secure access control and state reporting are required.

Features & Benefits

• IP67 ingress protection enables use in wet environments
• 24V solenoid control with power-to-unlock functionality
• Holds operation key with minimum 1,300N holding force
• Direct drive from control equipment reduces external modules
• Rated switching for 120V AC and 125V DC at 1.5A
• Screw Terminal connection simplifies field wiring

Applications

• Suitable for guard doors on automated production lines
• Ideal for machine safety access on conveyor systems
• used with lightweight hinged doors and aluminium frames
• Can be used for lock monitoring in PLC safety circuits
• Suitable for retrofit of safety enclosures with M20 conduit

What contact arrangements are available for monitoring?

The unit provides multiple built-in contact configurations including a 2NC/2NC safety contact set and options up to six contacts for separate door and lock monitoring.

How is the solenoid powered and what are its electrical demands?

The solenoid operates at 24VDC with an initial higher inrush for approximately 10s then a constant current

typical power consumption for a 4-contact variant is about 4.8W.

What mounting and conduit provisions exist for installation?

The switch accepts an M20 conduit outlet and can be mounted in several orientations

a conversion adapter is supplied for 1/2-14NPT variants where required.

Which terminal/connection types are provided for wiring?

Both screw Terminal and connector-type versions are available to suit differing wiring practices and connector cable lengths can be selected separately.

Are there user-access features to prevent entrapment?

A removable lockout key and slide handle arrangement allow personnel to secure the slide in the locked position to prevent others from closing the door while inside.
