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

2S, SO2, NH3, HNO3, Cl2) 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.
