QNHCK2-16 Split Core Hall Effect Current Sensor, 20A, 2.5V ±2V Output, Analog Clamp CT Transformer (50A 1.65V 0.625V PWR3.3V)

The QNHCK2-16 is a split-core Hall effect current sensor designed for accurate, non-invasive AC/DC current measurement across a wide range of applications. Its convenient clamp-style split core design allows for quick and easy installation directly onto existing wiring without the need to break or interrupt the circuit. With a rated current range spanning from ±10A up to ±150A, this versatile transducer handles everything from light-duty monitoring to more demanding industrial setups. It delivers a stable analog output centered at 2.5V with a ±2V swing, powered by a standard +5V supply, making it straightforward to interface with microcontrollers and data acquisition systems. The four color-coded output leads — Red (+5V), Yellow (Vout), Black (GND), and Blue (Vref) — simplify wiring and reduce installation errors. Accuracy and linearity are both rated at ≤1%, ensuring dependable, repeatable readings. Built to perform reliably in tough conditions, this sensor operates across a temperature range of -25°F to 185°F (-25°C to +85°C) and can be stored in temperatures as low as -40°F (-40°C). Ideal for energy monitoring, motor control, and power management systems.
