MY2K-US 24VDC

**General-purpose Latching Relay MYK** 

CSM_MYK_DS_E_1_3 

## **Magnetic Latching Relay Ideal for Memory and Data Transmission Circuits** 

- Double-winding latch system that holds residual magnetism. 

- Changes due to aging are negligible because of use of special magnetic materials, thus ensuring long continuous holding time. 

- Little change in characteristics such as contact follow, contact pressure, etc., throughout its long life. 

- Excellent vibration/shock resistance. 

- Easy monitoring of ON/OFF operation thanks to the built-in operation indicator mechanism. 

- Same outline dimensions as the MY Miniature Power Relay. 

Refer to the standards certifications and compliance section of your OMRON website for the latest information on certified models.

- **Note: 1.** For AC models, the rated current values are half-wave rectified current values measured with a DC ammeter. 

   **2.** The rated current and coil resistance are measured at a coil temperature of 23°C with tolerances of +15%/-20% for AC rated current and ±15% for DC rated current, and +15% for DC coil resistance. 

   **3.** The AC coil resistance values are for reference only. 

   **4.** Performance characteristic data are measured at a coil temperature of 5°C to 35°C.

- **Note: 1.** Resistor is for ampere-turn compensation and is incorporated in the Relay rated at 50 VAC or above. 

   **2.** Pay attention to the polarity of the set and reset coils, as incorrect connection of positive and negative terminal will result in the Relay malfunctioning.

When using the Relay rated at 110 VAC at a supply voltage of 220 VAC, be sure to connect external resistors Rs and Rr to the Relay. If the supply voltage is applied to the set and reset coils at the same time, the Relay will be put in the set state.
