Safety Sensors / Components
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
2
S, SO
2
, NH
3
, HNO
3
, Cl
2
) 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.
•
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 D4NH, production of the D4DH will be
terminated.
Date of Production Termination
Production of the D4DH Series will be terminated in March 2006.
Product Replacement
1.
Dimensions
The D4DH and D4NH 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 model, the terminals 21, 22, 23, and 24 on the
D4DH are 31, 32, 33, and 34 on the D4NH.
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.
Comparison of the D4DH and Substitute Products
List of Recommended Substitute Products
Using M screws is recommended to comply with European stan-
dards. Therefore, the M20 conduit model is recommended for use in
new designs.
