The contact resistance data are periodically measured reference values and are not values from each monitoring operation. Contact resistance values will vary
according to the switching frequency and operating environment, so be sure to check operation under the actual operating conditions before use.

Correct Use
• Long-term Continuously ON Contacts
Using the Relay in a circuit where the Relay will be ON
continuously for long periods (without switching) can lead to
unstable contacts, because the heat generated by the coil itself
will affect the insulation, causing a film to develop on the contact
surfaces. Be sure to use a fail-safe circuit design that provides
protection against contact failure or coil burnout.
• Relay Handling
When washing the product after soldering the Relay to a PCB,
use a water-based solvent or alcohol-based solvent, and keep
the solvent temperature to less than 40°C. Do not put the Relay
in a cold cleaning bath immediately after soldering.
