Omron G9KJ-1A DC12 relè PCB ad alte prestazioni 12 VDC 25 A 1 Form A

High-current switching on a PCB often forces designers to choose between compact size and reliable performance. The Omron G9KJ-1A DC12 high-power PCB relay solves that conflict by handling up to 25 A in a single-pole normally-open configuration, with a 12 VDC coil that fits standard through-hole layouts.

Who is it for

Engineers and technicians who need a robust, board-mounted relay for power control in industrial equipment, HVAC systems, appliances, or automation panels. It suits applications where space is limited but the load is not.

Tips

Ensure the PCB traces can carry the full load current and provide adequate clearance for the 250 VAC rating. The AgSnO2 contacts resist welding and arc erosion, making this relay suitable for frequent switching of resistive or slightly inductive loads.
