Coil Ratings
MY(S)
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 temperature 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 resistor if required.
MY2ZN, MY@F, MY4(Z)H
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.
Note: Refer to page 19 for the coil specifications of the MY2K.

Note: 1. Make sure that the polarity is correct.
2. The release time will increase, but the 20-ms specification for standard models is satisfied.

Safety Precautions
• For models with built-in operation indicators, check the coil polarity when
wiring and wire all connections correctly (DC operation).
• Use only combinations of OMRON Relays and Sockets.
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: 1. An AC model has coil disconnection self-
diagnosis.
2. For the DC models, check the coil polarity
when wiring and wire all connections
correctly.

2. 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.
3. The AC coil resistance is a reference value only.
4. Operating characteristics were measured at a coil temperature of 23°C.
5. The maximum voltage capacity was measured at an ambient temperature of 23°C.
Contact Ratings
*With no icing or condensation.

For AC
Note: R is a resistor for ampere-turn correction. This resistor is
built-in to 50-VAC and higher models.
(The coil has no polarity.)
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
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.

Connection Socket and Mounting Bracket Selection Table
(The possible combinations of models with plug-in terminals and sockets)
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 MYI@(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.)
Terminal Covers for PYFZ-08/PYFZ-14 Sockets
Note: These covers cannot be used for PYF08A and PYF14A.
Use these covers in a combination with PYFZ-08 and PYFZ-14.

Safety Precautions
Maximum Carry Current
• Do not allow the total current for all shorted contact form to exceed the maximum carry current of the Short Bar.
• Do not exceed the maximum carry current of the relay contacts for individual contact form.
• If you use more than one Socket, use End Plates (PFP-M).

Safety Precautions

-PU for precautions on Push-In Plus Terminal Block Sockets.
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 Flange-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 15.)
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.
