NK Technologies' AS1 Series Compact Case Current-Sensing Switch
AS1 Series compact case current-sensing switch monitors an energized circuit in tight spaces. The ring design slips onto a conductor to reliably detect currents as low as 0.5 A with a single conductor pass. Solid-state output provides a nearly unlimited number of operations. It can control ac or dc circuits to 120 V, with a maximum load capacity of 150 mA.
