NK Technologies AS1 NOR-FT-GO Series specialized Current Sensing Relay includes an electromechanical relay contact. This output allows the sensor to control much more current than other AS1 Current Sensing Relay models. This contact can control loads up to 5 A, AC or DC. Solid-state contacts generally have a much lower capacity, making this sensor much more versatile than most self-powered models. Available in only solid-core case.
