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

This solenoid interlock switch is a Compact guard-lock device designed to control access to hazardous areas and integrate with industrial control systems. It provides electrically controlled locking and unlocking of safety doors, operating within automation and machinery environments where monitored door status and lock monitoring are required. The unit features a metal enclosure with ingress protection suitable for harsher shop-floor conditions and supports conduit wiring for straightforward installation.

• IP67 protection prevents dust and temporary immersion
• Metal housing increases mechanical robustness for industrial use
• Power to lock/unlock at 4.8W enables direct solenoid drive
• Three auxiliary contacts supply additional monitoring outputs
• Rated for 120V AC and 125V DC contact switching at 1.5A
• Screw Terminal connection simplifies secure wiring installation

• Suitable for machine-guard monitoring on manufacturing lines
• Ideal for safety interlock on automated assembly cells
• Used with control panels requiring monitored lock feedback
• Can be used for access control on fabrication equipment

The device accepts an M20 conduit entry and includes an M20-to-1/2-14NPT conversion adaptor for alternate conduit threads.

Mechanical life is specified to a minimum of 1 million operations with electrical endurance up to 150,000 operations under a 1A resistive 125V AC load.

Typical power consumption for the locking Coil is 4.8W on 24V DC types during activation, with a starting higher-current interval before switching to a constant current.

Models offer versions with LED indication and either terminal-block or connector wiring to suit different installation and monitoring needs.

Actuators sold separately.
