Notes:
1. When ordering, add the rated coil voltage to the model number.
Example: G6S-2F DC12
Rated coil voltage
2. When ordering tape packing (surface mount models), add "-TR" to the model number.
Example: G6S-2F-TR DC12
Tape packing
"-TR" is not part of the relay model number. Therefore, it is not marked on the relay case.
3. Dual coil latching models are available with a High-sensitivity coil. (140 mW; 200 mW for DC24)
When ordering High-sensitivity dual coil latching models, add "-H” to the model number.
Example: G6SK-2G-H-TR DC5

The rated current and coil resistance are measured at a coil temperature of 23°C with a tolerance of
±10%.
The operating characteristics are measured at a coil temperature of 23°C.
Pick-up voltage will vary with temperature.
The maximum voltage is the highest voltage that can be imposed on the relay coil.
