QNHCK2-16 Split Core Hall Effect Current Sensor, 20A, 2.5±2V Output, +5V Supply, Clamp-On CT Transformer (100A 1.65V 0.625V PWR3.3V)

The QNHCK2-16 is a split-core Hall effect current sensor designed for accurate AC and DC current measurement across a wide range of applications. Featuring a convenient clamp-on design, this sensor installs easily around existing wires without the need to break or interrupt live circuits, saving time and reducing installation complexity. It supports a rated current range of ±10A up to ±150A, making it highly versatile for both light-duty and demanding industrial setups. The sensor operates on a +5V supply voltage and delivers a stable analog output of 2.5V ±2V, with accuracy and linearity both rated at ≤1%, ensuring reliable and precise performance monitoring. Color-coded leads (Red: +5V, Yellow: Vout, Black: GND, Blue: Vref) simplify wiring connections. Built to withstand an operating temperature range of -25°C to +85°C (-13°F to 185°F) and storage temperatures from -40°C to +125°C (-40°F to 257°F), this sensor is well-suited for industrial environments. Its compact and robust construction makes it an excellent choice for energy monitoring, power management systems, and industrial automation applications.
