Rated coil voltage
Note:
1. When ordering, add the rated coil voltage to the model number. Rated coil voltages are given in the coil ratings table.
Example: MY2, 6 VAC
*2. Models mark with an asterisk are not available with international safety standard ratings.
3. Add "-G" to the model number if mounting studs are required (e.g., MY4-G).
4. The standard contacts for MY2Z-series Relays and for the MY4Z are gold-plated.
**5. Models denoted by "" will be manufactured upon request. Ask your OMRON representative.
6. The following variations are also available.
Plastic-sealed relays (MYQ4):
See page 46.
Latching relays (MY2K):
See page 51.
Hermetically sealed relays (MY4H): Ask your OMRON representative.

Note:
1. The rated current and coil resistance are measured at a coil temperature of 23
C with tolerances of +15%/20% for rated currents
and
15% for DC coil resistance.
2. Performance characteristic data are measured at a coil temperatures of 23
C.
3. The must operate and must release voltages for High-sensitivity Relays was measured at the rated power supply voltage.
4. AC coil resistance and impedance are provided as reference values (at 60 Hz).
5. Power consumption drop was measured for the above data. When driving transistors, check leakage current and connect a bleeder
resistor if required.
