Characteristics

Note. The values given above are initial values at 23°C. (except electrical durability)

*1.

Measurement conditions: 6 VDC, 20 A (after 30 seconds) voltage drop method.

*2.

Measurement conditions: Applied rated coil voltage, no contact bouncing.

*3.

Measurement conditions: Measured with a 1,000 VDC megohmmeter at the same point as the dielectric strength was measured.

*4.

This specification is when diode and zener diode are used. For relay coil, please connect diode and zener diode.

For more detail, please refer to

Diode Connection for Operating Coil on page 4.

*5.

The humidity range of 25% to 75% conforms to the environmental conditions of JIS C 5442.

Also, refer to

Relay Service Life on page 5.

*6.

The value was measured at a switching frequency of 180 operations/ minute.

*7.

For the detail regarding holding voltage usage, please refer to

Coil Voltage Reduction (Holding Voltage) after Relay Operation on page 4.
