Omron D4SL Series Safety Switch, IP67, 2.5A Switch Contact Current - D4SL-N2HFA-DN


This safety switch is a guard‑lock interlock device designed to monitor and lock access to hazardous areas in industrial automation and machinery. It is suitable for integration into control circuits to detect door position and monitor lock status while offering protection against dust and water ingress for indoor applications.

Features & Benefits


• IP67 degree of protection enabling wash‑down and dust resistance
• Direct‑drive solenoid capability for controller operation
• Multiple contact configurations supporting up to six contacts
• Key holding force of 1300 N for secure door retention
• Rated for operation between −10 to 55 °C for varied environments
• Carry current 2.5A at 120V AC to handle standard control loads

**Applications**


• Suitable for guarding access on automated production lines
• Ideal for machinery with interlocked doors requiring lock monitoring
• Used with safety relays and PLC inputs for machine control systems
• Can be used on aluminium‑framed enclosures and lightweight doors
• Suitable for requiring a lock‑out key to prevent entrapment

What conduit entries are supported for cabling?


The unit accepts a G1/2 conduit entry and is available with alternative conduit options via adaptors for regional requirements.

How does the lock function integrate with control circuits?


The lock monitor contacts report solenoid power status while door‑detection contacts provide direct‑opening feedback to safety circuits.

What electrical ratings govern switching and Coil supply?


Contact switching is rated for 120V AC and 125V DC applications with maximum contact carry current values provided for standard loads

the solenoid operates at 24V DC.

Are there options for connector or Terminal connections?


Both connector and terminal‑block connection styles are offered to suit different wiring practices and cable assembly preferences.

What mechanical limits should be observed during installation?


The product delivers a defined holding force and mechanical durability

ensure correct mounting, stopper placement and use of specified screws to avoid excessive forces or misalignment.
