The QNHCK2-16 is a Hall Effect split-core current transducer designed for precise and reliable current monitoring across a wide range of applications. With a rated input of ±20A and a voltage output of 2.5V±2V, this sensor delivers accurate measurements from DC up to 25KHz, making it suitable for both low-frequency and high-frequency current sensing tasks. The split-core design allows for quick and easy installation by simply clamping around an existing conductor, eliminating the need to disconnect or rewire your circuit. Four color-coded leads (Red: +5V, Yellow: Vout, Black: GND, Blue: Vref) simplify wiring and integration into your system. The transducer features high galvanic isolation, ensuring safe operation in demanding electrical environments. It operates reliably across a temperature range of 14°F to 158°F, making it well-suited for both indoor and outdoor installations. The compact, robust housing is built to withstand everyday use, and the single-phase design makes it a versatile choice for energy monitoring, industrial automation, and power management systems.
