Omron D4GS Safety Interlock Switch, Keyed, Plastic, Keyed

Omron D4GS Series Safety Interlock Switch, 240V Contact AC Voltage, IP67 - D4GS-N2T

This safety interlock switch is a Compact keyed device designed to monitor access panels and guard doors in industrial systems. It provides a mechanically actuated safety function with normally closed safety contacts and a keyed lock style suitable for automated and manual safety circuits, while offering environmental protection for the main body to suit damp or wash‑down conditions.

Features & Benefits

• IP67 main‑body sealing protects against dust and temporary immersion
  2.5A thermal current supports moderate control loads
  NC safety contacts provide direct‑opening safety function
  Operating range −30°C to 70°C suits varied plant environments
  Two‑direction head accepts front or rear mounting
  Plastic housing reduces weight and resists corrosion

Applications

• Suitable for conveyor guarding in manufacturing lines
  Ideal for machine‑door interlocking on processing equipment
  Used with safety PLC inputs for access monitoring
  Can be used for packaging machinery perimeter protection
  Suitable for wash‑down areas where main‑body sealing is required

What voltages can it switch for control circuits?

It is rated for AC loads up to 240V and DC loads up to 250 V, with a conventional free‑air thermal current of 2.5 A.

How are the safety contacts configured for safety circuits?

The device uses normally closed contacts with a direct‑opening mechanism on specified NC terminals to assure positive opening under fault conditions.

What cable and installation considerations apply?

The factory‑fitted cable is UL2464 AWG22 with an outer diameter of 7.2 mm
secure the cable within 5 cm of the body and maintain a bending radius greater than 45 mm.

How does it cope with mechanical abuse and vibration?

It is designed with rubber mounting for the operation key to absorb vibration and meets vibration and shock‑resistance requirements for malfunction prevention.

What environmental limits affect its electrical endurance?

Electrical durability is specified as 100,000 operations at a 1A resistive load and performance may vary above 35°C, so higher‑current simultaneous circuits should be avoided.

Standards

Meets EN (TÜV) standards and CE marking requirements along with a variety of international standard requirements, such as UL and CSA requirements. All NC contacts satisfy requirements for the direct opening mechanism.
