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.

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.

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;

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.

■ 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 and release to free position.
