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.
■
Cautions
Handling
To avoid an electric shock or a fire, be sure to turn OFF the D3M
before mounting, removing, wiring, or servicing.
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.
!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.
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;
Voltage
(V)
30
0.16mA
100mA
24
Operating
range
12
Inoper-
able
range
1mA
0.1
1
10
100mA
1,000
100
Current (mA)
5
0
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.
