Struthers-Dunn 112XAX229 Relay

Struthers-Dunn 112XAX229 Dunco Relay is a compact SPDT (1 Form C) electromechanical relay designed for 115 V AC coil operation and 60 Hz service, featuring an open-style package suitable for panel mounting. The 112XAX229 variant provides a single Form C contact rated for 1 A AC, making it well-suited for routing control signals or switching modest AC loads in industrial automation, instrumentation, and process-control panels. As part of the Struthers-Dunn Dunco lineage, this relay is designed for reliable operation in standard 115 VAC control circuits, with coil activation by a 115 VAC supply and compatibility with common North American wiring practices. Applications include interlocking, sequencing, isolation, and signal transfer in machine controls, safety circuits, and relay logic where a dedicated 1 A Form C contact is required without the bulk of higher-power relays.
