Product Description

The PI550 0R4G1 is a precision current sensor integrated with a 0.4 Ohm shunt resistor, designed for accurate current measurement in industrial applications such as power management, motor control, and battery monitoring. With a single input and analog/digital output, it directly interfaces with microcontrollers or signal conditioning modules. Operating within a voltage range of 1.8V to 5.5V and a temperature range of -40°C to +125°C, this sensor supports stable performance in harsh environments. It features a compact form factor, eliminating the need for additional components like screens or batteries. Key advantages include high accuracy (±0.5%), low temperature coefficient, and minimal power dissipation. However, its 0.4 Ohm resistance may introduce measurable voltage drop in high-current scenarios. The device is optimized for systems requiring reliable current sensing up to 10A, with a focus on energy efficiency and real-time diagnostics in automation and energy sectors.
