Always verify with datasheet because pin arrangements can vary slightly.
Why does the perform so reliably in harsh environments? The answer lies in its construction. omron g8b-201-01
Omron uses a silver alloy (typically AgSnO₂ - Silver Tin Oxide) for the contacts. Silver tin oxide is superior to pure silver because it resists arc-induced transfer and welding. This material is specifically chosen for DC loads, where arcing is more sustained than with AC loads. Always verify with datasheet because pin arrangements can
The G8B uses a high-efficiency polarized magnetic circuit. This allows for a smaller coil that still generates sufficient magnetic force to overcome spring tension and the contact pressure needed for 20A continuous current. omron g8b-201-01
