Omron D4SL-N Series Solenoid Interlock Switch, Power to Unlock

Omron D4SL-N Series Solenoid Interlock Switch, 24V DC Supply Voltage, IP67 - D4SL-N4PFA-DN

This solenoid interlock switch is designed to secure access to hazardous areas by preventing door closure or release until safe conditions are met. It operates with a 24 V DC solenoid and is intended for industrial safety-door applications where monitored door and lock status are required. The unit features a resin enclosure and Terminal Block connection for integration into safety circuits, and it meets relevant electrical and machinery directives for use in controlled environments.

Features and Benefits:

• IP67-rated enclosure for protection against dust and temporary immersion
  Power-to-unlock solenoid consumes 4.8 W at 24 V DC for controlled release
  Three NC safety contacts enable monitoring of door and lock status
  Direct-opening mechanism supports use in safety circuits per EN 60947-5-1
  M20 conduit entry simplifies European conduit installations
  Rated contact current 1.5 A for common industrial control loads

Applications

• Used with guarded machinery requiring monitored access control
  Suitable for lightweight doors with slide-key lockout function
  Ideal for assembly-line enclosures needing interlocked access
  Can be used where IP67 protection against contaminants is required
  Used in systems requiring compliance with UL 508 safety standards

What supply voltage and power consumption are required?

The Coil requires 24 V DC and the solenoid consumes approximately 4.8 W when energised.

How are safety contacts configured for monitoring?

The unit provides three normally closed contacts that report door and lock conditions to safety circuits.

Which conduit size should I plan for when installing?

The device uses an M20 conduit entry suitable for standard European installations.

What housing material and environmental protection does it have?

The housing is MADE of resin and the enclosure is rated to IP67 for protection against dust and temporary immersion.

What contact load can be switched reliably?

Contacts are rated for a switching current of 1.5 A and utilisation categories per EN 60947-5-1.
