Omron MY2K-US 12VDC Latching Power Relay Guide

The Omron MY2K-US 12VDC latching power relay is a compact relay designed for maintained switching in industrial, control, and electronic equipment. It belongs to the MYK latching relay group and is commonly used where the relay must keep its contact position without continuous coil power.

Technical Overview

Omron data for the related MY2K DC12 version describes a two-pole latching miniature power relay with plug-in terminals, a 12 VDC coil, DPDT contact form, and gold-plated silver contacts. Listed coil data includes separate operate and release coil characteristics, reflecting the latching design. Distributor data for MY2K-US-DC12 also identifies it as a 12 VDC DPDT relay with socketable or plug-in style use.

The DPDT format provides two changeover contacts in one relay. This is useful in control circuits where two separate signals must change state at the same time. Because the relay is latching, it only needs coil energy during the set or reset action, not continuously during the held state.

Practical Benefits

The Omron MY2K-US 12VDC latching power relay is suitable for applications that require energy-saving operation, retained position, or reduced coil heating. In battery-supported systems, low-duty control circuits, signal selection equipment, or machine control panels, a latching relay can offer a practical advantage over a continuously energized relay.

Important Selection Factors

Before using this relay, confirm the exact suffix, terminal style, socket compatibility, coil voltage, contact rating, and approval requirements. The MY2K family contains multiple versions, so a small difference in suffix can indicate a different terminal arrangement or certification package. Designers should also review whether the circuit provides separate set and reset signals required by the latching mechanism.

FAQ

What is the Omron MY2K-US 12VDC latching power relay?

It is a 12 VDC latching relay with DPDT contacts, designed to maintain its switched position after the coil pulse is removed.

Omron MY2K-US 12VDC Does it need constant coil power?

No. A latching relay only requires energy to change state. After that, the contact position is mechanically retained.

What does DPDT mean in this relay?

DPDT means double pole double throw. It allows two circuits to be switched between normally open and normally closed paths.

Is MY2K-US 12VDC the same as every MY2K 12 VDC relay?

Not always. Suffixes may indicate terminal type, certification, or regional configuration. The full order code should be checked before replacement.

Why use a latching relay instead of a standard relay?

A latching relay is useful when energy saving, lower coil heating, or retained contact state is important for the control system.
