The QNHCK2-16 is a Hall Effect split-core current transducer designed for precise and reliable current measurement across a wide range of applications. With a rated input of ±20A and a voltage output of 2.5V±2V, this sensor delivers accurate readings from DC all the way up to 25kHz, making it suitable for both steady-state and dynamic current monitoring tasks. The split-core clamp design allows for quick and easy installation directly onto existing wiring without the need to disconnect or interrupt the circuit. Powered by a single +5V supply, it integrates seamlessly into most control and monitoring systems. The four color-coded output wires (Red: +5V, Yellow: Vout, Black: GND, Blue: Vref) simplify wiring and setup. A robust 2,500V galvanic isolation between the primary circuit and the signal output ensures safe operation in demanding environments. The sensor operates reliably in temperatures ranging from 14°F to 158°F, making it well-suited for industrial, energy monitoring, and automation applications. Available in multiple input ranges from ±10A up to ±150A to meet a variety of current sensing needs.
