Note: 1.
The above values are initial values.
2.
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 D4NL in places where foreign material may penetrate through the key hole on the head, otherwise Switch damage or mal-
functioning may occur.
3.
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 OM-
RON representative.
4.
If the ambient temperature is greater than 35° C, do not pass the 3-A, 250-VAC load through more than 2 circuits.
5.
These figures are minimum requirements for safe operation.
6.
This figure is based on the GS-ET-19 evaluation method.
7.
This value will vary with the switching frequency, environment, and reliability level. Confirm that correct operation is possible with the actual
load beforehand.

Circuit Connection Example
•
Terminals 12 and 41 are connected internally and so connect termi-
nals 11 and 42 for safety-circuit input. (GS-ET-19)
•
Connect terminals 21 and 22 and terminals 51 and 52 in series
when using as safety-circuit input (redundancy circuit for terminals
11 and 12 and terminals 41 and 42 above). Connect the terminals
individually when using as auxiliary-circuit input (e.g., terminals 21
and 22 for safety-door open/closed monitoring and terminals 51
and 52 for monitoring the lock status).
•
In the connection example on the right, terminals 21 and 22 and
terminals 51 and 52 are used as auxiliary-circuit input.

•
Direct opening contacts used as safety-circuit input are indicated
with the
mark. Terminals 11 and 12 and terminals 21 and 22
are direct opening contacts.
•
Connect the indicators in parallel to the auxiliary circuits or termi-
nals E1 and E2.
If an indicator is connected in parallel to a direct opening contact,
when the indicator breaks, a short-circuit current will be generated,
possibly resulting in an installation malfunction.
•
Do not switch standard loads for more than 2 circuits at the same
time. Otherwise, the level of insulation may decrease.
•
The 24-VDC solenoid has polarity. Be sure to connect terminals
with the correct polarity.
