New Latching Levers for Circuit Checking
Added to Our Best-selling
MY General-purpose Relays
• Reduces wiring work by 60% when combined
with the PYF-PU Push-In Plus Socket
(according to actual OMRON measurements).
• Now lead-free to protect the environment.
• VDE certification (Germany).
• Different colors of coil tape for AC and
DC models to more easily distinguish them.
• MY(S) models with latching levers added for
easier circuit checking.
Refer to the Common Relay Precautions.

Note: 1. The models in this table are UL/CSA certified. This is indicated with a certification mark on the products.
(This does not include models with high contact reliability or plastic sealed, latching, or hermetically sealed models.)
2. Models with an asterisk (*) next to them are new versions.
3. The standard models with plug-in terminals, models with coil surge absorption diodes, and models with coil surge absorption CR circuits were used in
combination with the PYF@A-E, PYF@-S and PYF-@-PU for the EC Declaration of Conformity. These products display the CE Marking.
4. Products cannot be manufactured for the cells with a diagonal line. Ask your OMRON representative for details on manufacturing products for cells containing
“---” in the above table.

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.
*2. There is variation between products, but actual values are 30% minimum for AC and 10% minimum for DC. To ensure release, use a value that is lower than the specified value.

Reset power supply
• 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

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 shortcircuiting 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.

Note: Refer to Common Socket and DIN Track Products for the external dimensions of the Socket Relays and details on Hold-down Clips.
*1. The information in parentheses is the model number of the applicable Mounting Bracket. Mounting Brackets are sold in sets of two. However, the PYC-P is just
one Mounting Bracket.
*2. The PYF@A-E has a terminal cover with finger protection. The Socket and Terminal Cover are integrated into one unit. Round terminals cannot be used.
Use forked terminals or ferrules instead.
*3. A Push-In Plus Terminal Block Socket functions as a release lever to hold or remove a Relay. Refer to PYF-@@-PU/P2RF-@@-PU for details.
*4. If an MY@I(S) Relay with a Latching Lever is used in combination with a PY@-02 Socket for Relays with PCB Terminal Socket and PYC-P Mounting Brackets, the
lever will not operate.
*5. We recommends using the PYC-E1 Mounting Bracket for a MY2I(S) Relay with Latching Lever. (If the PYC-A1 is used with the MY2I(S), the latching lever will be
blocked by the Mounting Bracket and the lever will not operate.)
*6. The Mounting Brackets are applicable for Relays with a height of 36 mm or less. If the Relay height is greater than 53 mm, use Y92H-3 for the Front-mounting
Socket and PYC-1 for the Back-mounting Socket. (The Y92H-3 is a set of two Brackets and the PYC-1 is just one Bracket.)

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.

Safety Precautions
Refer to the Common Relay Precautions.
Precautions for Correct Use
Handling
About the Built-in Diode and CR Elements
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).
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.
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.
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
• Use two M3 screws to attach case-surface-mounted models (MY@F) and
tighten the screws securely (tightening torque: 0.98 N•m).
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.
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.)
