Safety Precautions
• For applications that use a 200 VAC power
supply, connect external resistors Rs and Rr to
a 100 VAC Relay.
• Do not apply a voltage to the set and reset coils at the
same time. If you apply the rated voltage to both coils
simultaneously, the Relay will be set.
• The minimum pulse width in the performance column is
the value for the following measurement conditions: an
ambient temperature of 23° C with the rated operating
voltage applied to the coil. The performance values
given here may not be satisfied due to use over time
and a reduction in latching performance due to
changes in the ambient temperature or in the
conditions of the application circuit.
For actual use, apply the rated operating voltage with a
pulse width based on the actual load and reset the
Relay at least once per year to prevent degradation
over time.
• If the Relay is used in an environment with strong
magnetic fields, the surrounding magnetic field can
demagnetize the magnetic body and cause unintended
operation. Therefore, do not use these Relays in
environments with strong magnetic fields.
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.
Applicable Sockets
Use only combinations of OMRON Relays and
Sockets.

Safety Precautions
PCB Design for Hermetically Sealed Relays
When a Relay with PCB Terminals is mounted, a short-circuit can occur
depending on the design of the PCB pattern because the Relay itself is made
out of metal.
Solution
Refer to the external dimensions of the Relay and design the PCB pattern with
enough space to prevent this problem.
Applicable Sockets
Use only combinations of OMRON Relays and Sockets.
Application Environment for Hermetically Sealed
Relays
Humid environments can cause insulation problems, which may result in short-
circuiting or unintended operation.
Solution
Do not use these Relays in any environment where the Relay will come into
contact with water vapor, condensation, or water droplets. This can reduce the
surface tension of the insulating beads and cause short-circuiting or unintended
operation due to poor insulation.
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.

Compliance with Electrical Appliances and Material Safety Act
• All standard models comply with the Electrical Appliances and Material
Safety Act.
• Always protect any exposed terminals (including Socket terminals) after
wiring with insulation tubes or resin coating on PCBs.
*Under the Electrical Appliances and Material Safety Act, do not use any 4-
pole models with a voltage that exceeds 150 VAC. However, this restriction
can be ignored if compliance with the Electrical Appliances and Material
Safety Act is not required.
Safety Precautions
Refer to the Common Relay Precautions.
Handling
For models with a built-in operation indicator, models with a built-in diode, or
high-sensitivity models, check the coil polarity when wiring and wire all
connections correctly (DC operation).
Installation
• There is no specifically required installation orientation, but make sure that
the Relays are installed so that the contacts are not subjected to vibration or
shock in their movement direction.
• Use two M3 screws to attach case-surface-mounted models (MY@F) and
tighten the screws securely (tightening torque: 0.98 N•m).
Using MY-series Relays with Microloads with
Infrequent Operation
If any standard MY-series Relays (e.g., MY4) are used infrequently to switch
microloads, the contacts may become unstable and eventually result in poor
contact. In this case, we recommend using the MY4Z-CBG Series, which has
high contact reliability for microloads (Refer to page 25.)
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.
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.
Latching Levers
• Turn OFF the power supply when operating the latching lever. After you use
the latching lever always return it to its original state.
• Do not use the latching lever as a switch.
• The latching lever can be used for 100 operations min.
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.

combination of the Product in the Buyer’s application or use of the Product. At Buyer’s request, Omron will provide applicable
third party certification documents identifying ratings and limitations of use which apply to the Product. This information by itself
is not sufficient for a complete determination of the suitability of the Product in combination with the end product, machine,
system, or other application or use. Buyer shall be solely responsible for determining appropriateness of the particular Product
with respect to Buyer’s application, product or system. Buyer shall take application responsibility in all cases.

it to actual application requirements. Actual performance is subject to the Omron’s Warranty and Limitations of Liability.
Change in Specifications.
Product specifications and accessories may be changed at any time based on improvements and other reasons. It is our
practice to change part numbers when published ratings or features are changed, or when significant construction changes are
made. However, some specifications of the Product may be changed without any notice. When in doubt, special part numbers
may be assigned to fix or establish key specifications for your application. Please consult with your Omron’s representative at
any time to confirm actual specifications of purchased Product.
