Omron D4NL Series Solenoid Interlock Switch, IP67, 35.5mm Width - D4NL-4CFA-B4

This solenoid interlock switch is a guarded-door safety device designed for industrial automation and access control. It combines a solenoid-operated locking mechanism with auxiliary monitoring to manage hazardous access during machine operation. The unit is intended for indoor factory use where electromagnetic locking and safety-contact monitoring are required to control personnel access and machine states.

Features & Benefits

• IP67 protection for ingress resistance and harsh environments
• Two NC safety contacts for direct-opening safety circuits
• Power-to-lock/unlock capability for controlled access management
• Contact ratings accommodate 110V AC and 250V DC circuit use
• Compact 88.5mm length for space-constrained installations

Applications

• Suitable for interlocking machine guards on production lines
• Ideal for safety doors on material-handling equipment
• Used with control contactors in motor protection circuits
• Can be used for perimeter access on robotic cells
• Suitable for retrofit replacements where M20 conduit is present

What conduit entry does it support for cable routing?

The device provides an M20 conduit opening to accept standard M20 cable glands and connectors.

Which electrical loads are compatible with the safety contacts?

The auxiliary contacts handle microloads and standard loads with a contact current rating of 50mA for low-current circuits.

How are indicators and auxiliary circuits recommended to be wired?

Indicators should be connected in parallel to auxiliary outputs or dedicated indicator terminals

avoid paralleling with direct-opening contacts to prevent short-circuit–induced malfunctions.

Are there specific Terminal fastening requirements during installation?

Terminal screws require a tightening torque range to ensure reliable connections and prevent loose strands

use appropriate crimp terminals for AWG20–AWG18 conductors.

Note
