NOTE: The values here are initial values.

1.Measured with 10 mA at 1 VDC with a voltage drop method.

2.Measured with a 500 VDC megohmmeter between coil and contacts and a 250 VDC megohmmeter between contacts with the same polarity applied to the same parts as those used for checking the dielectric strength.

3.This value was measured at a switching frequency of 120 operations/min and the criterion of contact resistance is 100Ω.
This value may vary depending on the switching frequency and operating environment. Always double-check relay suitability under actual operating conditions.
Note:1. Each value has a tolerance of ±0.3 mm.

Correct Use

●Long-term Continuously ON Contacts

Using the Relay in a circuit where the Relay will be ON continu- ously 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℃. Do not put the Relay in a cold cleaning bath immediately after soldering.
