■Ratings
●Coil
Note 1. The rated current and coil resistance are measured at a coil temperature of 23°C with a tolerance of ±10%.
Note 2. The operating characteristics are measured at a coil temperature of 23°C.
Note 3. The “Max. voltage” is the maximum voltage that can be applied to the relay coil.
* These numbers are only for -PW type. Power consumption with Holding Voltage is 32mW. Please confirm the detail in page 6 Coil Voltage Reduction (Holding
Voltage).

■Characteristics
Note. Values in the above table are the initial values at 23°C.
*1. Measurement conditions: 5 VDC, 1 A, voltage drop method
*2. Measurement conditions: Measured at the same points as the dielectric
strength using a 500 VDC ohmmeter.
*3. This value was measured at a switching frequency of 120 operations/min.
*4. Sealed (G5NB-1A4, -1A4-E): -40°C to 70°C
