Current Sensing Switch monitors circuits in tight spaces.
November 18, 2011 -
Featuring 1 in. housing with ring design, AS1 Series-CC slips onto conductor to detect currents as low as 0.5 A with single conductor pass. Powered directly from monitored circuit, switch monitors and reports electric motor load status, identifies open heater circuit connections, and verifies that load is energized. Contact can control AC or DC circuits to 120 V, with max load capacity of 150 mA. With solid-state output and no moving parts, switch provides nearly unlimited operations.

Easily Monitor Energized Circuits in Tight Spaces with new AS1 Compact Case Current Sensing Switch from NK Technologies
Ring design easily slips onto a conductor to give a solid state contact for cost effective and reliable current flow indication as low as 0.5 amps
SAN JOSE, CA - NK Technologies introduces the AS1 Series Compact Case Current Sensing Switch. With its tiny 1 inch housing, the AS1 is a compact and cost-effective solution that enables users to monitor an energized circuit in tight spaces. The easy-to-use ring design easily slips onto a conductor to reliably detect currents as low as 0.5A with a single conductor pass, eliminating the need to wrap conductors multiple times. Reliable, solid-state output with no moving parts provides a nearly unlimited number of operations.
"The AS1 Series-CC current sensing switch is a powerfully simple solution to complicated control requirements. When a user needs to know that a circuit is energized but they don't want to cut into the insulation or add burden to the monitored circuit, a current operated switch is the best solution. And when the primary circuit draw is less than 50 amps, a small, well-insulated device such as the AS1 is just what is needed," says Philip Gregory, President, NK Technologies.
The AS1 has 24 inch leads that can be connected directly to controller input terminals or brought out to a terminal block to facilitate remote operation. The contact can control either AC or DC circuits to 120 volts, with a maximum load capacity of 150mA. There is near zero off-state leakage providing positive indication of the presence of AC current, and the output easily handles the coil of an industrial quality relay.
This current sensing switch is powered directly from the monitored circuit to monitor and report electric motor load status, identify open heater circuit connections and independently verify that a load is energized. It is also useful for confirming current flow to and operation of critical lighting and other equipment such as fans, heaters, pumps or other AC powered devices. The AS1 is rated for use in ambient temperatures ranging from -4 to 122 degrees F (-20 to 50 degrees C).
