D4GS-N2R

What type of component is this?

It is a key-operated safety door switch from Omron’s D4GS-N series, designed for guard door interlocking applications on industrial machinery.

What is the typical application for this switch?

It is typically used to detect whether a machine guard, access door or protective cover is closed, helping control machinery access in automated production environments.

How many contacts does it have?

The D4GS-N2R has 2 normally closed contacts and 0 normally open contacts.

What contact action does this model use?

This model uses slow-action switching, meaning the contact operation follows the movement of the actuator key rather than snapping over at a set point.

What is the direction of key insertion?

The key insertion direction is horizontal, making it suitable for installations where the actuator enters the switch body from the side.

Does this switch include guard locking?

No. This model is a key-operated safety door switch and does not include a guard-lock function.

Does it have an LED indicator?

No. This version does not include an LED indicator.

What cable length is supplied with this model?

The standard D4GS-N2R version is supplied with a 1 metre cable. A related version, D4GS-N2R-3, uses a 3 metre cable.

What is the ingress protection rating?

The switch body is rated IP67, offering strong protection against dust ingress and temporary water immersion under defined test conditions.

What operating temperature range is specified?

The specified operating ambient temperature range is -30 °C to 70 °C.

What are the main dimensions of the sensor body?

The sensor body is approximately 85 mm long, 17 mm high and 30 mm wide.

How is the switch connected electrically?

It uses an integrated cable connection rather than a conduit or plug-in connector.

What is the shape of the switch body?

The switch has a compact cuboid body, making it suitable for use where installation space is limited.

Are actuator keys included as part of the switch body specification?

The switch is used with a separate D4GS-N operation key. Compatible accessories listed for the series include horizontal and adjustable operation key options.

What mounting style is this component suited to?

Its slim body and horizontal key entry make it suited to guard door installations where the actuator key approaches the switch from the side.

What does the 2NC contact configuration mean in practice?

A 2NC configuration means the unit has two normally closed circuits that are opened when the actuator key is removed from the switch.

Is this model fitted with conduits?

No. It has no conduits and uses a fixed cable connection.

What electrical ratings are associated with the D4GS-N series?

The series documentation lists ratings including AC-15 at 0.75 A, 240 V and DC-13 at 0.27 A, 250 V, subject to correct application conditions.

What is the minimum positive-opening force specified for the series?

The D4GS-N series documentation specifies a minimum positive-opening force of 60 N.

What is the mechanical life rating for the series?

The series documentation lists a mechanical life of at least 1,000,000 operations under specified conditions.
