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.
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.
Production Discontinuation
Following the release of the D4N, production of the D4D-N will be
discontinued.
Date of Production Discontinuation
Production of the D4D-N Series will be discontinued as of the end of
March 2006.

Operating method
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.
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.
If the recommended terminals are not used, the Switch may not
be compatible. Make sure that the Switch is compatible with the
terminals.

Others
• Do not allow the load current to exceed the rated value.
• Confirm that the seal rubber has no defects before use.
• Use the correct cover mounting screws only, or the sealing
• Inspect the Switch regularly.
• Make sure that foreign particles do not enter the head when
• Use the following recommended countermeasures to prevent
1. Make the rear edge of the dog smooth with an angle of 15 to 30
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.
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.
