The HNC-05LX with Current Sensors Through Hole RoHS manufactured by ZhongXu is a type of current sensor consisting of a series of components including a printed circuit board, resistor, Shunt, lead wires, and an isolation resistor. It is designed to provide a precise and proportional signal for current measurement. The HNC-05LX is an Isolated AC/DC current switch and provides five levels of detection with adjustable hysteresis (0.5A/0.5A, 1A/1A, 2A/2A, 4A/4A, and 8A/8A). This device is RoHS compliant, which means that it does not contain any hazardous materials that may be harmful to human health or the environment. The product is able to measure AC/DC currents from 0.5A to 10A, and is ideal for use in industrial, commercial, and residential applications.
