General-purpose Relays

• The standard models include models that are

compliant with the UL, CSA, and SEV safety

standards and with the Electrical Appliances and

Material Safety Act.

• Equipped with an arc barrier for arc interruption.

• Withstand voltages up to 2,000 V.

• New built-in diode and built-in CR circuit models have

joined the series.

• The lineup also includes models that are compliant

with the LR and VDE safety standards.

• Single-pole and double-pole models have AC4 ratings

and DC2 ratings (operating coil ratings: 100/110 VAC,

110/120 VAC, 200/220 VAC, 220/240 VAC, and 100/

110 VDC).

• Three-pole and four-pole models have AC4 ratings

and DC2 ratings (operating coil ratings: 100/110 VAC,

200/220 VAC and 100/110 VDC).

Model Number Structure

Note: 1. Cells with a diagonal line cannot be manufactured. Ask your OMRON representative for details on manufacturing products for cells

containing “---” in the above table.

2. If #187 tab terminals are required, use the LY1F-T2 or LY2F-T2 (single-pole or double-pole models only).

3. Refer to page 16 for information on plug-in terminal and socket combinations.

4. Items with an asterisk (*) in the table are certified for UL, CSA, and SEV. This is indicated with a certification mark on the products.

5. Items with two asterisks (**) in the table are certified for UL and CSA. This is indicated with a certification mark on the products.

6. All models in the table are certified for IEC (TÜV).

7. The models with plug-in terminals (single-pole, double-pole, and 4-pole) were combined with the PTF-E for the EC Declaration of

Conformity. These products display the CE Marking.
