Ordering Information
■Open Relays
Note: 1. When ordering, add the rated coil voltage to the model number. Rated coil voltages are given in the coil ratings table.
2. Relays with #187 quick connect terminals are also available with SPDT and DPDT contact. Ask your OMRON representative for details.
3. SEV models are standard Relays excluding DPDT (bifurcated) models.
4. VDE- or LR- qualifying Relays must be specified when ordering.

Three-pole Relays
Note: See notes under next table.
Four-pole Relays
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 re-
sistor if required.

■Hold-down Clips
Hold-down clips are used to hold Relays to Sockets and prevent them from coming loose due to vibration or shock.
Precautions
Refer to page A-72 for general precautions.
■Connections
Do not reverse polarity when connecting DC-operated Relays with
built-in diodes or indicators.
