The Omron MY2N Plug-in Relay delivers dependable signal isolation, auxiliary interlock switching, and high electrical endurance engineered specifically for industrial control panels, packaging automation, motor starter circuits, and HVAC interface skids.

Industrial Switching Precision with the Omron MY2N Plug-in Relay

Designed as the global benchmark for miniature general-purpose control devices, the Omron MY2N Plug-in Relay provides responsive Double Pole Double Throw (DPDT) contact commutation. Capable of handling continuous currents up to 5 A across AC and DC loads, the unit effectively bridges low-voltage PLC digital transistor outputs to heavy industrial contactors, solenoid valves, and audible signaling beacons.

The relay incorporates dual visual diagnostic features that streamline routine plant maintenance. A high-brightness operational LED illuminates upon coil energization, while a physical mechanical flag confirms positive contact armature displacement. Its durable transparent polycarbonate dust cover shields precision silver alloy contacts against airborne debris, oil mist, and dust contamination commonly present in high-density electrical cabinets.

Key Features and Engineering Advantages

• Dual Status Diagnostics: Combines an integrated operating LED indicator with an optical mechanical indicator flag for rapid field troubleshooting.
• Heavy-Duty Silver Alloy Contacts: Premium contact metallurgy provides minimal contact resistance and reduces contact erosion during inductive load switching.
• High Dielectric Isolation: Sustains up to 2,000 V AC dielectric withstand voltage between coil and contact circuits to prevent electrical transient crossover.
• Standard Octal Base Architecture: Uses standard 8-pin plug-in spade terminals, facilitating rapid tool-free relay replacement on front-connecting DIN-rail sockets.
• Certified Industrial Compliance: Fully compliant with international safety benchmarks including UL, CSA, CE, and VDE standards.

Frequently Asked Questions

What does the “N” suffix indicate in the Omron MY2N relay designation?
The “N” designation specifies that the relay is equipped with both a built-in operation indicator LED and a mechanical status indicator flag, enabling technicians to visually diagnose coil power status and contact armature movement at a glance.

Which DIN-rail socket models pair with the Omron MY2N Plug-in Relay?
The relay pairs with Omron’s 8-pin front-connecting socket bases, including the standard screw-terminal PYF08A-E and the push-in Plus terminal socket PYFZ-08-E, both designed for standard 35 mm DIN-rail snap mounting.

Are diode-suppressed models available for DC PLC output cards?
Yes. For sensitive transistor output cards susceptible to inductive back-EMF spikes during coil de-energization, the MY2N-D2 sub-variant features a built-in reverse-biased surge suppression diode connected directly across the coil terminals.
