Note: 1. It is recommended that M20 be used for Switches to be exported to Europe and 1/2-14NPT be used for Switches to be exported to North
American countries.
2. All models have slow-action contacts with approved direct opening mechanisms on NC contacts only.
3. The 1/2-14NPT 2-conduit models include an M20-to-1/2-14NPT changing adaptor.

Note: 1. The values in the table on the previous page 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 D4NH 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. For safe use, make sure that the allowable operating speed is not exceeded.
7. This value will vary with the switching frequency, environment, and reliability level. Confirm that correct operation is possible with the ac-
tual load beforehand.

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 formlock construction which remains
secure even when the
screw becomes loose.
Head
The head can be mounted in four directions.
Conduit
A wide variety of conduits is available.

Note: M12 connector types are not available for

Guard Closed
Forced
separation
of NC contacts
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.
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.
* The housing and head of the D4NH are made of resin. Use D4BS Miniature
Electromagnetic Lock Safety Door Limit Switches for applications requiring
safety door switches of tough, high-sealing, or oil-resistant construction.

Note: 1. Terminals are numbered according to EN50013. Contact forms are according to EN60947-5-1.
2. MBB (Make Before Break) contacts have an overlapping structure, so that before the normally closed contact (NC) opens, the normally
open contact (NO) closes.
