Omron D4GS Series Safety Interlock Switch, 85mm Length, IP67 - D4GS-N2R

This safety interlock switch is a compact, key-operated device designed to monitor and secure movable guards and access doors in industrial control systems. It is intended for environments where a slim profile and protected enclosure are required, providing direct-opening safety contacts compatible with control and safety circuits.

Features & Benefits

• IP67 main-body sealing resists dust and temporary immersion
  Rated for AC 240V and DC 250V operation supporting mixed loads
  Contact current capacity of 2.5A for conventional thermal current
  Operates across -30°C to 70°C ambient temperatures for wide use
  Plastic enclosure reduces weight and resists corrosion in wet areas

**Applications**

• Suitable for guarding on machine access doors and hatches
  Ideal for integration with PLC safety inputs and indicators
  Used for securing enclosures in washdown or high-humidity zones
  Can be used in assembly-line interlocks where Compact size matters

What cable options and lengths are available for installation?

Cable is UL2464 AWG22 with an outer diameter of 7.2mm and is offered in standard lengths of 1m, 3M and 5m to suit different mounting distances.

Are multiple contact configurations provided for different safety architectures?

Yes, selectable slow-action contact arrangements include 1NC/1NO, 2NC, 2NC/1NO and 3NC to match a range of safety and signalling requirements.

What mechanical endurance can be expected under normal conditions?

Mechanical life is specified at a minimum of 1 million operations, while electrical endurance is 100,000 operations under a 1A resistive 125V AC load.

How should the key be mounted to prevent operational issues?

The operation key must be secured with M4 screws and mounted so it cannot contact users
rubber mounting absorbs vibration and reduces shock transmission.

What protection class and insulation details apply to electrical safety?

The unit meets Class II double-insulation standards and provides dielectric strength and impulse withstand values per EN60947-5-1 for safe separation between circuits.
