Omron MY2-02-US-SV 220/240VAC Electromagnetic Relay Guide

The Omron MY2-02-US-SV 220/240VAC electromagnetic relay is a compact industrial relay designed for dependable switching in control panels, automation systems, and equipment boards. It is part of the Omron MY relay family and is commonly associated with DPDT switching, PCB terminal construction, and a 220/240 VAC coil rating.

Technical Profile

This relay is typically specified as a two-pole, double-throw relay, giving engineers two changeover circuits in one compact device. The 220/240 VAC coil allows the relay to operate in control systems where line-derived AC control voltage is available. The PCB terminal format supports direct board installation, which can simplify wiring and improve manufacturing consistency.

Distributor data commonly identifies this model as a DPDT electromagnetic relay with a 230 VAC class coil and contact current capability around 5 A for many listed operating conditions. As with all relays, the practical switching rating depends on whether the load is resistive or inductive. Inductive loads such as contactor coils, valves, and small motors can stress contacts more heavily than resistive loads.

Application Areas

The Omron MY2-02-US-SV 220/240VAC electromagnetic relay is used in automation boards, machine control circuits, interface panels, interlocking circuits, and signal transfer systems. Its DPDT arrangement is helpful when two circuits must change state at the same time, such as switching a control signal while also providing status feedback.

Selection Notes

Engineers should confirm coil voltage, contact rating, terminal style, load category, ambient temperature, and agency approval requirements before specifying this relay. A relay with the correct coil voltage can still be unsuitable if the load has high inrush current or if the circuit requires a socket-mounted part instead of PCB pins.

FAQ

What is the Omron MY2-02-US-SV 220/240VAC relay used for?

It is used for general-purpose switching, control signal transfer, automation interfaces, and board-level relay circuits.

Omron MY2-02-US-SV 220/240VAC Does this relay have DPDT contacts?

Yes. It is commonly listed as a DPDT relay, meaning it provides two changeover contact sets.

Is this a plug-in relay?

This specific code is commonly associated with PCB terminals. Always compare the terminal layout with the circuit board or socket design before replacement.

Can it replace another MY2 relay?

Only when coil voltage, terminal style, contact rating, contact arrangement, and approval requirements match the original part.

Why does the contact rating change by load type?

Inductive loads create electrical stress during switching. Because of that, their allowable current rating is usually lower than a simple resistive load rating.
