Recommended Connectors
Use connectors with screws not exceeding 9 mm, otherwise the
screws will protrude into the case interior, interfering with other
components in the case. The connectors listed in the following table
have connectors with thread sections not exceeding 9 mm. Use the
recommended connectors to ensure conformance to IP67.
Use LAPP connectors together with seal packing (JPK-16, GP-13.5,
GPM20, or GPM12), and tighten to the specified tightening torque.
Seal packing is sold separately.
LAPP is a German manufacturer. Ohm Denki is a Japanese
manufacturer.
Before using an M12 type, attaching the provided changing adaptor
to the Switch and then connect the recommended connector.
Before using a 2-conduit 1/2-14NPT type, attach the provided
changing adaptor to the Switch and then connect the recommended
connector.
Storage
Do not store the Switch in locations where hazardous gases (e.g.,
H

S, SO
2
, NH

, HNO

, Cl

) or dust is present, or in locations subject
to high temperatures and humidity.
Others
•
Do not allow the load current to exceed the rated value.
•
Confirm that the seal rubber has no defects before use.
If the seal rubber is displaced or raised, or has foreign particles
adhered to it, the sealing capability of the seal rubber will be
adversely affected.
•
Use the correct cover mounting screws only, or the sealing
capability of the seal rubber will deteriorate.
•
Inspect the Switch regularly.
•
Make sure that foreign particles do not enter the head when
removing the screws from the four corners to change the head
position in any of the four directions.
•
Use the following recommended countermeasures to prevent
telegraphing when using adjustable or long levers.
1.
Make the rear edge of the dog smooth with an angle of 15
°
to 30
°
or make it in the shape of a quadratic curve.
2.
Design the circuit so that no error signal will be generated.
3.
Use or set a Switch that is operated in one direction only.
Production Termination
Following the release of the D4N, production of the D4D-N will be ter-
minated.
Date of Production Termination
Production of the D4D-N Series will be terminated in March 2006.
Product Replacement
1.
Dimensions
The D4D-N and D4N use the same mounting method, and
mounting hole. The multi-contact structure and the extra 4 mm in
length, however, are different.
2.
Terminal Numbers
For the 2-contact slow-action model, the terminals 21, 22, 23, and
24 on the D4D-N are 31, 32, 33, and 34 on the D4N.
3.
Recommended Terminals
If the recommended terminals are not used, the Switch may not
be compatible. Make sure that the Switch is compatible with the
terminals.
