Equipment
• Lineup includes three contact models with 2NC/1NO and
3NC contact forms in addition to the previous contact forms
1NC/1NO, and 2NC. Models with MBB contacts are also
available.
• Standardized gold-clad contacts provide high contact
reliability. Can be used with both standard loads and
microloads.
Be sure to read the
“Safety Precautions”
on page 9.

Note: 1.
The above values are initial values.
2.
Once the contacts have been used to switch a load, however, they cannot be used to switch smaller loads. The contact surfaces will
become rough once they have been used and contact reliability for smaller loads may be reduced.
*1.
The degree of protection is tested using the method specified by the standard (EN60947-5-1). Confirm that sealing properties are sufficient for
the operating conditions and environment beforehand. Although the switch box is protected from dust or water penetration, do not use the
D4NH in places where foreign material such as dust, dirt, oil, water, or chemicals may enter through the head. Otherwise, accelerated wear,
Switch damage, or malfunctioning may occur.
*2.
The durability is for an ambient temperature of 5 to 35°C and an ambient humidity of 40% to 70%. For more details, consult your
OMRON representative.
*3.
Do not pass the 3 A, 250 VAC load through more than 2 circuits.
*4.
Be sure to provide this amount to ensure safety in operation.
*5.
This value will vary with the switching frequency, environment, and reliability level. Confirm that correct operation is possible with the actual
load beforehand.

the guard
Guard Open
Arm Lever
The arm lever is mounted upwards in the center
position before shipping. To change the position,
loosen the arm lever mounting screw, dismount
the arm lever, and mount the arm lever in the left
or right position.
The joint between the shaft and
arm lever is formed with
form-lock construction which
remains secure even when the
screw becomes loose.
When the guard is opened, the cam that is directly coupled to
the shaft rotates to press the Switch in the direction shown by
the (vertical) arrow. This action separates the contacts to stop
the machine.
Head
The head can be mounted in four directions.
Conduit
A wide variety is available.
Size
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.
Note:
The housing and head of the D4NH are made of resin. Use D4BS
Safety-door Switches for applications requiring safety door switches of tough,
high-sealing, or oil-resistant construction.
