Omron MY2N-D2 12VDC (S)

Omron MY2N-D2 12VDC (S) Miniature Power Relay

The Omron MY2N-D2 12VDC (S) miniature power relay is a compact DPDT relay designed for 12 VDC control circuits, automation panels, signal switching, and general-purpose industrial applications. It combines plug-in installation, LED operation indication, and a built-in diode for coil surge absorption.

Omron specifies this relay as a 2-pole miniature power relay with single contacts, plug-in terminals, a closed cover, and silver contact material. Its 12 VDC coil draws 72.7 mA and has a coil resistance of 165 ohms. The rated contact load includes 220 VAC 5 A for resistive loads and 24 VDC 5 A for resistive DC loads. :contentReference[oaicite:2]{index=2}

Why the 12 VDC Version Matters

Many control systems use 12 VDC for auxiliary circuits, battery-backed equipment, access systems, small machine controls, and low-voltage automation. The Omron MY2N-D2 12VDC (S) miniature power relay provides a practical interface between a 12 VDC control signal and separate AC or DC load circuits.

Common Use Cases

This relay can be used in battery-powered control systems, low-voltage automation, test benches, security panels, lighting control circuits, and interface modules. The DPDT structure gives designers flexibility when switching two circuits, reversing logic states, or separating control and load wiring.

The built-in diode is especially useful when the relay coil is driven by a transistor, microcontroller interface, or PLC output module. By absorbing the coil’s reverse voltage, it helps improve circuit reliability and reduces stress on the driving component.
