Easily Accessible Information!

Product Information at a Glance

The model, specifications, and safety standards are all provided on the top surface.
You can check this information while the Relay is mounted in the Socket.

Contact Status at a Glance

Mechanical indicators are now a standard feature so that you know the contact operating status even for standard models.

Different Looks for Different Specifications

To prevent incorrectly using the Relays, we’ve made it easy to tell the difference between Relays with different specifications.

Note:
1. The rated current and coil resistance are measured at a coil temperature of 23°C with tolerances of +15%/−20% for the AC rated current and +15% for the DC coil resistance.
2. The AC coil resistance and inductance values are reference values only (at 60 Hz).
3. Operating characteristics were measured at a coil temperature of 23°C.
4. The values in parentheses for the rated currents and coil voltages of DC coils are for models with LED operation indicators.
5. The maximum voltage capacity was measured at an ambient temperature of 23°C.
*1. There is variation between products, but actual values are 80% max.
The Relay will operate if 80% or higher of the rated voltage is applied. However, to achieve the specified characteristics, apply the rated voltage to the coil.
*2. There is variation between products, but actual values are 30% minimum for AC and 10% minimum for DC. To ensure release, use a value that is lower than the specified value.
