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: LY2, 6 VAC
2. Relays with #187 quick connect terminals are also available with SPDT and DPDT contact. Ask you OMRON representative for
details.
3. SEV models are standard relays only. Relays with built-in varisters have not met overseas standards.
4. VDE- or LR- qualifying relays must be specified when ordering.

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. AC coil resistance and impedance are provided as reference values (at 60 Hz).
4. Power consumption drop was measured for the above data. When driving transistors, check leakage current and connect a bleeder
resistor if required.

1. The values given above are initial values.
*2. The upper limit of 40
C for some relays is because of the relationship between diode junction temperature and the element used.
