MY

New Latching Levers for Circuit Checking

Added to Our Best-selling

MY General-purpose Relays

• 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.

Model Number Structure

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-E and PYFS (2-pole and 4-pole) 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.

Ordering Information

Note: 1. Ask your OMRON representative for details on the time required to deliver made-to-order products.

2. Ask your OMRON representative for details on product specifications and the ability to manufacture products with voltages other than

the above coil specifications.

3. The above models and specifications are new versions in the MY Series.

4. Except for MY2(N)-CR Relays with the above voltage specifications, all Relays have a height of 53 mm or less.

If Mounting Brackets are required, refer to page 33 for selection information.

Ratings and Specifications

Ratings

Operating Coils (Standard Models)

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. 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.

Contact Ratings

*1. With no icing or condensation.

*2. This limitation is due to the diode junction temperature and elements used.

Operating Coil (Standard Models)

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.

• 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.

• The UL and CSA certifications for this model are the same as for the MY4-

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.

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.
