- Reduces wiring work by 60% when combined with the 

- PYF-PU Push-In Plus Socket 

- (according to actual OMRON measurements). 

- 10 A (DPDT) and 5 A (4PDT) 

- Gold-clad contacts (MY4(S)) 

- Test button (lockable) 

- Wide portfolio includes hermetically sealed and latching types 

- 2.6 mm wide pins offer higher conductivity and less temperature increase

- **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.

- **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:** 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.

(The coil has no polarity.) 

## **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 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.

## **Sockets for MY** 

## **DIN-rail-mounted (DIN-rail) Socket Conforms to VDE 0106, Part 100** 

- Snap into position along continuous sections of any mounting DIN-rail. 

- Facilitates sheet metal design by standardized mounting dimensions. 

- Design with sufficient dielectric separation between terminals eliminates the need of any insulating sheet.

   **2.** The values for insulation resistance were measured at 500 VDC at the same place as the dielectric strength. 

   **3.** The maximum operating ambient temperature for the PYF08A-N and PYF14A-N is 55°C. 

   **4.** When using the PYF08A-N or PYF14A-N at an operating ambient temperature exceeding 40°C, reduce the current to 60%. 

   **5.** The MY2(S) can be used at 70°C with a carry current of 7 A.

**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.)

## **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).

**Refer to** _**Products Related to Common Sockets and DIN Tracks**_ **for precautions on the applicable Sockets. Refer to** _**PYF-**_ @@ _**-PU/P2RF-**_ @@ _**-PU**_ **for precautions on Push-In Plus Terminal Block Sockets.** 

## ~~Po~~ **Precautions for Correct Use** 

## **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. 

## **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. 

- 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.)
