Omron D4SL Series Safety Switch, 120V Contact AC Voltage, IP67 - D4SL-NSK10-LKH


This safety switch is a guarded interlock device designed to secure access to hazardous areas within industrial automation and machinery systems. It provides monitored door detection and lock monitoring for safety circuits, is suitable for lightweight doors and aluminium-frame mounting, and operates across typical factory conditions between −10 to 55 °C.

Features & Benefits


• IP67 rating for weatherproof operation and wash‑down environments
• Rated operating current 1.5A for industrial control loads
• 24V DC solenoid drive with reduced steady‑state power consumption
• Direct‑opening contacts enable use in safety circuits
• Holding force 1300 N to keep access points secured
• Electrical endurance up to 150,000 operations for contact switching

**Applications**


• Suitable for guarding panels and enclosures on assembly lines
• Ideal for integration with conveyor guard doors and hatches
• Used with control panels requiring monitored lock status feedback
• Can be used for machine access on lightweight hinged doors
• Suitable for retrofit to 40 x 40 mm aluminium safety frames

What voltages can the control contacts handle?


Contact ratings cover AC operation to 120V and DC operation to 125V for low‑voltage signalling.

How does the device indicate lock and door states?


A built‑in Orange LED provides Visual indication of the lock/door status when fitted with the indicator option.

What environmental limits should be observed for reliable operation?


Operate between −10 to 55°C with up to 95% relative humidity and avoid immersion in oil or continuous splashing.

How is the unit mounted and connected electrically?


It mounts in multiple orientations and supports terminal‑block or connector wiring methods

connector cables are available separately.

What mechanical endurance can be expected for the slide key assembly?


The slide key unit is specified for a minimum mechanical durability of 20,000 operations.
