Coil voltage and contact arrangement — the BOM-fit gates
The G2R-1: The 110 V AC coil voltage is the primary selection criterion for panel retrofit or BOM replacement — if your control circuit runs on 110 V AC, this relay drops in without a separate transformer or DC power supply. The 1 CO (SPDT) output switches one circuit between normally-open and normally-closed positions, covering simple on/off, interlock, or signal-routing tasks in a single relay footprint. Rated at 10 A continuous, the contacts handle moderate resistive loads directly; for inductive loads like small contactors or solenoid valves, apply a derating factor per the load type — the 10 A figure is the resistive ceiling, not the inductive ceiling.
Flux protection and temperature envelope — panel placement constraints
The -10 to 40 °C operating range limits placement to climate-controlled or moderate-temperature enclosures; if the panel sits near a heat source or in direct sunlight, the ambient temperature may exceed the upper bound and degrade coil life or contact reliability.
Lifecycle status and documentation for qualified BOM lines
Omron provides datasheets, material declarations, and RoHS/REACH compliance documentation that supports the audit trail for qualified installations — request the specific cert pack at RFQ to maintain traceability.
