Omron MY3 Compact Miniature Electromechanical Relay

Omron MY3 Compact Miniature Electromechanical Relay is a small, general-purpose relay designed to switch electrical loads in control circuits. The MY3 model is part of Omron’s compact MY series, delivering dependable electromechanical switching in a tiny package. Coil voltages listed for this part include 240 VAC, 28 VDC, and 110–120 VAC, highlighting its versatility across different mains and control‑voltage environments. The compact footprint makes it well suited for space-constrained control panels and instrumentation enclosures where reliability is important. As with other electromechanical relays, the MY3 energises a coil to move contacts, providing galvanic isolation between control and load circuits. The Omron name behind it reflects a long-standing standard in industrial relays, offering a compact solution for applications requiring mechanical switching in a small form factor.
