Omron MY2 12VAC (S) Miniature Power Relay

The Omron MY2 12VAC (S) miniature power relay is a compact electromechanical relay designed for reliable switching in low-voltage AC control systems. It belongs to Omron’s MY relay family, a widely used series in industrial automation, machine control, electrical panels, and auxiliary control circuits. With a 12 VAC coil and a DPDT contact configuration, this relay is suitable for applications where two separate circuits need to be switched from a single control signal.

Technical Characteristics

The Omron MY2 12VAC (S) uses a 12 VAC coil and a two-pole changeover contact arrangement. The DPDT design allows the relay to switch two independent circuits, each with normally open and normally closed contact paths. This makes it useful in control logic, signal transfer, interlock circuits, alarm systems, and equipment status switching.

Its plug-in terminal structure supports socket-based installation, which is especially valuable in control cabinets where fast replacement and simplified maintenance are important. Instead of rewiring the relay during service, technicians can replace the relay body while keeping the socket wiring intact.

Electrical Performance and Use Cases

The relay is commonly applied in circuits involving moderate AC or DC loads, depending on the approved load rating and installation conditions. Its silver alloy contacts are designed for general-purpose switching, while the enclosed body helps protect the internal mechanism from normal panel environments.

The Omron MY2 12VAC (S) miniature power relay is often selected for low-voltage AC control circuits, small machine interfaces, automation panels, HVAC control logic, and relay-based sequence control. For related Omron relay products and technical references, visit Omron relay information.

Omron MY2 12VAC (S) FAQ

What is the Omron MY2 12VAC (S)?

It is a miniature plug-in power relay with a 12 VAC coil and DPDT contact configuration, designed for general-purpose control and switching applications.

What does DPDT mean in this relay?

DPDT means double pole double throw. It allows the relay to switch two separate circuits, with each pole changing between normally open and normally closed contacts.

Where is this relay commonly used?

It is commonly used in control panels, automation systems, machine interfaces, alarm circuits, interlock systems, and auxiliary electrical control circuits.

Why is socket mounting useful?

Socket mounting makes maintenance easier because the relay can be replaced without disconnecting the entire wiring arrangement.

Is Omron MY2 12VAC (S) suitable for industrial panels?

Yes, it is well suited for industrial control panels when the coil voltage, contact rating, socket type, and load characteristics match the system design.
