Series Overview
Series Overview
OMRON's relay portfolio includes G2R and MY plug-in electromagnetic relays for control panels, compact G6B interface/power relays and G3NA/G3NB solid-state relays. The complete suffix defines critical coil and contact details.
Part-number Structure & Selection Notes
It is necessary to confirm the contact form (SPDT/DPDT, etc.), coil voltage, contact capacity, whether it has LED/mechanical indication/test button, and matching base. The SSR also needs to confirm the load voltage, current and input control voltage. Generalizations such as "G2R are all 5A" cannot be used in place of complete specifications.

When purchasing relays, you must also confirm the contact form, contact capacity, coil/input voltage, indicator light/test button/diode, and base or terminal method. You cannot replace it based on the series name alone.
Specifications must be confirmed against the applicable official datasheet and ordering information. Regional variants, suffixes and configurations are not automatically interchangeable.
FAQ
Frequently Asked Questions
How do I confirm the complete part number for G2R / MY / G6B / G3NA relay?
It is necessary to confirm the contact form (SPDT/DPDT, etc.), coil voltage, contact capacity, whether it has LED/mechanical indication/test button, and matching base. The SSR also needs to confirm the load voltage, current and input control voltage. Generalizations such as "G2R are all 5A" cannot be used in place of complete specifications.
What are the main differences between G2R-1-SN (S) DC24 and G2R-2-SN (S) DC24?
contacts / type: G2R-1-SN (S) DC24 is SPDT plug-in, G2R-2-SN (S) DC24 is DPDT plug-in. Verify the complete ordering code and project conditions before selection or replacement; the series name alone is not sufficient.
Which specifications matter most when selecting G2R / MY / G6B / G3NA relay?
Key specifications to verify are series, contacts / type, coil / input, key notes. Match them against the equipment nameplate, drawing or original model, and retain every suffix, option and regional code in the complete ordering reference.
Why is the complete part number required when requesting a quote for G2R / MY / G6B / G3NA relay?
Models within G2R / MY / G6B / G3NA relay may differ in electrical ratings, construction, interfaces or accessories. For example, G2R-1-SN (S) DC24, G2R-2-SN (S) DC24, G2R-1-SNI (S) DC24 are distinct configurations and cannot be interchanged on the series name alone. Using the complete part number substantially reduces mismatch risk.
