Note:
1.The rated current and coil resistance are measured at a coil temperature of 23°C with tolerances of +15%, –20% for AC rated current and ±15% for DC coil resistance.
2.The AC coil resistance values are for reference only.
3.Performance characteristics data are measured at a coil temperature of 23°C.
4.The rated current of the AC operating coil is half-wave rectified current and is measured with a DC ammeter.
5.The peak reverse-breakdown voltage of the built-in diode is 1,000V.
6.The set coil of the Relay rated at 6 VDC is of the 5-minute rating. However, when it is used by connecting a diode is series, it can be of the continuous rating.
7.By connecting an external resistor to each of the set and reset coils as shown in the table below, the rated current of the Relay can be increased.
8.The maximum voltage is one that is applicable instantaneously to the Relay coil at 23°C and not continuously.

| Resistance | Capacity | Resistance | Capacity | ||
| 110 VAC | 100 VAC | 0.27 kΩ | 0.5 W min. | 0.39 kΩ | 1/4 W min. |

| 100 VDC | 48 VDC | 1.1 kΩ | 10 W min. | 2.0 kΩ | 6 W min. |
Note:Use a resistor having the above resistance value with tolerances of ±10% for external connection.

Note:
1.The data shown above are initial values.
2.The contact resistance was measured with 0.1 A at 5 VDC using the fall-of-potential method.
3.The set or reset time was measured with the rated voltage imposed with any contact bounce ignored at an ambient temperature of 23°C.
4.The insulation resistance was measured with a 500-VDC megger applied to the same places as those used for checking the dielectric strength.
5.The electrical endurance was measured at an ambient temperature of 23°C.
6.This value was measured at a switching frequency of 60 operations per minute.
Caution: In the interenst of product improvement, specifications are subject to change without notice.
