Contact Data
* 0.25A at 125VAC for latching models
Note: P level: λ60 = 0.1 x 10–6/operation
This value was measured at a switching frequency of 60 operations/min and the criterion of contact resistance is 50 Ω. This value may vary
depending on the switching frequency and operating environment. Always double-check relay suitability under actual operating conditions.

Note: 1. The contact resistance was measured with 10 mA at 1 VDC with a fall-of-potential method.
2. Values in parentheses are typical values unless otherwise stated.
3.
The insulation resistance was measured with a 500-VDC megohmmeter applied to the same parts as those for checking the dielectric strength
(except between the set and reset coil).
4. The above values are initial values.

Precautions
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. Otherwise, use a latching relay.
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 clean-
ing bath immediately after soldering.
