Subminiature Snap Action Switch

D3M

Precautions

Be sure to read the precautions and information common to all Snap Action and Detection Switches, contained in the Technical User’s Guide,

“Snap Action Switches, Technical Information” for correct use.

■ Correct Use

Mounting

Make sure that the surface to which the D3M is mounted is flat. If the

surface is not flat, the housing may distort, and the D3M may

malfunction, or the housing may crack.

Operating Stroke

Make sure that the dog is separated from the actuator when the actu-

ator is in the free position and that the actuator is pressed appropri-

ately when the D3M is actuated. The actuator must not be pressed

excessively to reach the maximum overtravel position, or the D3M

may be damaged.

Make sure the actuator is pressed in the direction where the D3M is

actuated.

Using Microloads

Using a model for ordinary loads to switch microloads may result in

faulty operation. Instead, use the models that are designed for

microloads and that operate in the following range;

However, even when using microload models within the operating

range shown above, if inrush current or inductive voltage spikes

occur when the contact is opened or closed, then contact wear may

increase and so decrease the service life. Therefore, insert a contact

protection circuit where necessary.

Wiring

The terminals connect to JST’s Dipole XA Connector.

The Dipole XA Connector consists of the following components.

Contact: SAX-001T-P0.6

Housing: XAP-02V-1

OMRON does not sell the Dipole XA Connector.

Contact J.S.T. Manufacturing Co. for these connectors.

■ Cautions

Handling

To avoid an electric shock or a fire, be sure to turn OFF the D3M

before mounting, removing, wiring, or servicing.

!CAUTION

The voltage and current applied to the D3M must be within the rat-

ed ranges when it is turned ON, turned OFF, and in operation, or

the service life of the D3M may be shortened. Also note that if in-

appropriate voltage and current are applied, the D3M may radiate

heat and burn.
