Power-switching Compact  
General-purpose Relays  
• Wiring work can be shortened by as much as 60%*  
compared to conventional screw terminal sockets by  
combining with push-in plus terminal sockets (PYF-
@
–  
PU) that feature light insertion force and strong pull-  
out strength to achieve less wiring work.  
• 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.  
Refer to the standards certifications and compliance section of your  
OMRON website for the latest information on certified models.  
• When both push-in plus terminals and screw terminal  
sockets are combined with plug-in terminal types  
(according to actual OMRON measurements as of November 2015)  
Refer to the
Common Relay Precautions

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 20 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.

Note: 1.
The rated current and coil resistance are measured at a coil temperature of 23°C with tolerances of +15%/–20% for the AC rated current and ±15% for the  
DC coil resistance.  
2.
The AC coil resistance and inductance values are reference values only. (at 60 Hz).  
3.
Operating characteristics were measured at a coil temperature of 23°C.  
4.
The maximum voltage capacity was measured at an ambient temperature of 23°C.  
*1.
There is variation between products, but actual values are 80% max.  
To ensure operation, apply at least 80% of the rated value (at a coil temperature of +23° C).  
*2.
The actual values are 30% min. for AC and 10% min. for DC. To ensure release, use a value that is lower than the specified value.

Safety Precautions  
Refer to the
Common Relay Precautions
for precautions that apply to all Relays.  
Precautions for Correct Use  
• Use
 
two M3 screws to attach case-surface-mounted models  
(LY1F, LY2F, LY3F, and LY4F) and tighten the screws securely.  
(Normal tightening torque: 0.98 N·m)  
About the Built-in Diode and CR Elements  
The diode or CR element that are built into the Relay are designed to  
absorb the reverse voltage from the Relay coil. If a large surge in  
voltage is applied to the diode or CR element from an external source,  
the element will be destroyed.  
• For
 
Relays with Tab Terminals, select a wire diameter for the lead  
wires that connect to the faston receptacle terminals that is within  
the allowed range for the load current.  
• Do
 
not impose excessive external force on the Relay when  
inserting the Relay to the faston receptacle or pulling the Relay out  
from the faston receptacle. Do not attempt to insert a terminal  
diagonally or insert or pull out more than one terminal at the same  
time.  
If there is the possibility of large voltage surges that could be applied  
to the elements from an external source, take any necessary surge  
absorption measures.  
Applying 10 A or More When Using an LY1 with  
the Following Sockets  
When you use an LY1 in combination with the PTF-08-PU, PTF-08-  
PU-L, PTF08A, PTF08A-E, or PT08, connect each of the following  
terminal pairs: (1) to (2), (3) to (4), and (5) to (6).  
• LY
 
Single-contact Relays are for power switching applications. Do  
not use the LY Series for switching minute loads of 100 mA or less,  
such as signals.  
Relay Replacement  
To replace the Relay, turn OFF the power supply to the load and  
Relay coil sides to prevent unintended operation and possible  
electrical shock.  
Attaching and Removing Relay Hold-down Clips  
When you attach a Hold-down Clip to or remove it from a Socket, wear gloves  
or take other measures to prevent injuring your fingers on the Hold-down Clip.
