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.

Solution Refer to the external dimensions of the Relay and design the PCB pattern with enough space to prevent this problem. Applicable 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. Use only combinations of OMRON Relays and Sockets.

Refer to Common Socket and DIN Track Products for the external dimensions of the Socket Relays. 4. 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.) 5.

If an MY@(S) Relay with a Latching Lever is used in combination with a PY@@-02 Socket for Relays with PCB Terminals and a PYC-P Mounting Brackets, the lever will not operate. 8. We recommends using the PYC-E1 Mounting Bracket for a MY2(S) Relay with Latching Lever. (If the PYC-A1 is used with the MY2(S), the latching lever will be blocked by the Mounting Bracket and the lever will not operate.)

Model MY Number of poles Coil ratings Contact ratings 1 2 3 6 to 220 VAC 6 to 120 VDC 5 A, 200 VAC 4* 6 to 110 VAC 6 to 120 VDC 3 A, 115 VAC * Under the Electrical Appliances and Material Safety Act, do not use any 4pole 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. 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.) 34 Terms and Conditions Agreement Read and understand this catalog.
