OMRON MY2N-J General Purpose Relay – Obsolete MY2 Series Spare Part

RFQ support for obsolete parts: Send the model number, required quantity and destination so DriveKNMS can confirm sourcing options before quotation.

Technical Specifications

Note: Coil voltage variants exist (e.g. AC100V, AC200V, DC24V). Confirm your required coil voltage at time of inquiry. Electrical parameters beyond those listed above are not confirmed here — do not assume compatibility without cross-referencing your original panel drawings.

Solving the Discontinued Hardware Crisis

The OMRON MY2N-J has been installed in control panels across machine tools, conveyor systems, packaging lines, and building automation infrastructure since the 1980s and 1990s. Many of these systems were engineered around the MY2 form factor — the 8-pin plug-in footprint, the mechanical indicator, the LED option — and replacing the relay with a non-identical substitute introduces re-wiring risk, socket incompatibility, and potential PLC logic conflicts.

Facilities running Mitsubishi MELSEC, Siemens S5-series, or older Omron C-series PLCs frequently rely on MY2-type relays as interface elements between the controller output and field devices. In these architectures, the relay is not a commodity — it is a precision interface component whose physical and electrical characteristics are baked into the original engineering drawings.

Condition & Reliability Assurance

Obsolete parts sourced from secondary markets carry inherent risk. DriveKNMS applies a 5-step quality assurance process to every MY2N-J unit before dispatch review:

1. Visual and mechanical inspection. Coil housing, contact bridge, and plug-in pins are examined for physical damage, pin corrosion, and case deformation. Units with oxidized or bent pins are rejected.
2. Electrolytic capacitor assessment. Where applicable in relay driver circuits, capacitor aging is evaluated. Bulging, leakage, or elevated ESR readings result in unit rejection.
3. Contact resistance measurement. Contact resistance is measured to confirm it falls within the original specification envelope. High-resistance contacts indicate wear or contamination and are cause for rejection.
4. Coil continuity and insulation verification. Coil resistance is checked for continuity and compared against expected values for the specific coil voltage variant. Insulation resistance between coil and contacts is verified.
5. Firmware and marking verification. Date codes, country-of-origin markings, and OMRON part number labels are cross-referenced against known-genuine references to screen for counterfeit units.

Key Features for System Maintenance

How do I confirm the unit is genuine and not counterfeit?
Every unit is inspected against known-genuine reference markings. Inspection records are available. We do not source from unverified brokers. If you require additional authentication documentation, request it at time of inquiry.

Can you supply other OMRON MY2-series variants?
