Omron D4N-R DATASHEET

Miniature Manual Reset Limit Switch

D4N-@R

New Series of manual-reset Limit Switch

• Lineup includes three contact models with 2NC/1NO and 3NC contacts in addition to the 1NC/ 1NO, and 2NC version. Version with MBB contacts meet applications for avdanced requirements.

• M12-connector models are available, saving on labor and simplifying maintenance.

• Standardized gold-clad contacts provide high contact reliability. Can be used with both standard loads and microloads.

• Free of lead, cadmium, and hexavalent chrome, reducing the burden on the environment.

• Conforms to EN115 and EN81-1.

Be sure to read the “Safety Precautions” on page G-277.

Note: Contact your sales representative for details on models with safety standard

certification.

Ambient temperature Operating: −30° C to 70° C with no icing Ambient humidity Operating: 95% max. Weight Approx. 92 g (D4N-1A20R)

Note: 1. The above values are initial values.

2. Once a contact has been used to switch a standard load, it cannot be used for a load of a smaller capacity. Doing so may result in rough-

ening of the contact surface and contact reliability may be lost.

3. The degree of protection is tested using the method specified by the standard (EN60947-5-1). Confirm that sealing properties are suffi-

cient for the operating conditions and environment beforehand. Although the switch box is protected from dust or water penetration, do not use the D4N-@R in places where foreign material such as dust, dirt, oil, water, or chemicals may penetrate through the head. Otherwise, premature wear, Switch damage or malfunctioning may occur.

4. The durability is for an ambient temperature of 5° C to 35° C and an ambient humidity of 40% to 70%. For more details, consult your

OMRON representative.

5. If the ambient temperature is greater than 35° C, do not pass the 3-A, 250-VAC load through more than 2 circuits.

6. This value will vary with the switching frequency, environment, and reliability level. Confirm that correct operation is possible with the ac-

tual load beforehand.

Structure, Names, and Functions

Structure

Safety-oriented Lever Setting

Grooves which engage the lever are cut in the lever and rotary shaft to prevent the lever from slipping against the rotary shaft. The actuator locks (self-holding) when it moves to the lock position.

Reset Head (Blue)

The direction of the reset head can be adjusted to any of the four directions.

Built-in Switch

The built-in switch has a direct opening mechanism that forcibly separates the NC contact even when there is contact deposit.

Cover

The cover, with a hinge on its lower part, can be opened by removing the screw of the cover, which ensures ease of maintenance and wiring.

Head

With roller lever models, the direction of the switch head can be adjusted to any of the four directions by loosening the roller lever switch screws at the four corners of the head.

Conduit

A wide variety of conduits is available.
