■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.

■Characteristics

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.

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.

■Approvals

UL Recognized (File No. E41515) / CSA Certified (File No. LR31928) - - Ambient Temp. = 40°C

Note: 1. The rated values approved by each of the safety standards (e.g., UL and CSA) may be different from the performance characteristics

individually defined in this catalog.

2. In the general interest of product improvement, specifications are subject to change.

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.
