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
This product does not have waterproof or drip-proof construction.
Ensure that water does not enter the switch interior. In particular, do
not use the switch in locations where water may be spilled or flow
over the switch. Doing so may result in deterioration of the insulation.
Also, if the contact is kept open for long periods of time, it is recom-
mended to use a sealed switch to prevent sulfuration of the contacts.
Pay attention to the creepage distance and clearance distance for
insulation after wiring onto the terminals, when the mounting frame is
made of metal.
■
Cautions
Handling
Do not expose the switch to shocks, such as by dropping it. Doing so
may damage or deform the switch.
Do not apply lubrication to the sliding parts, such as pushbuttons or
actuators. Doing so may result in faulty operation or contact failure.
In order to ensure stable contact force for contacts, actuate beyond
the recommended operating point (NO contact) and release to free
position (NC contact).
Wiring
Do not use the switch with a large force applied to the connector or
lead wire. Doing so may result in rattling or contact failure.
Recommended Operating Position
(3)
Storage Environment
Storing the switch in a plastic bag will help prevent discoloration due
to sulfuration of the (silver-plated) terminals.
Do not use the switch in locations subject to harmful gases or to high
temperatures or humidity levels. Depending on the location, it is rec-
ommended that switches be inspected between 3 and 6 months after
the date of manufacture.
Micro Loads
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

12

0.1
1mA

100mA

1,000
Current (mA)
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.
Connectors
The terminals connect to JST’s XA Connector.
The XA Connector consists of the following components.
Contact: SXA-001T-P0.6
Housing: XAP-02V-1
Omron does not sell the XA Connector.
Contact J.S.T. Manufacturing Co. for these connectors.
