The ACS71240 current sensor module uses the Hall effect to accurately and safely measure AC and DC current, providing electrical isolation of the current path. With a wideband analog output (up to 120 kHz) and low conduction resistance (0.6 mΩ), it minimizes energy loss and offers a fast response time of less than 5 µs. Pololu 5241
Description
The ACS71240 current sensor module is a modern solution based on the Hall effect, providing electrical isolation of the current path. This allows it to be placed anywhere in an electrical circuit while ensuring safe and precise current measurement. The sensor features a noise-resistant design, eliminating the influence of uniform magnetic fields such as the Earth's field. With a low conduction path resistance (0.6 mΩ) and 2 oz copper layers, energy losses are minimized.
The sensor provides a wide-band analog output (up to 120 kHz) proportional to AC or DC current, with a response time of less than 5 µs. A unique feature of this model is its voltage output independent of supply voltage, ensuring resistance to interference. The built-in overcurrent detection function with a 1.5 µs response time allows for rapid short-circuit detection and system protection. The module operates over a wide temperature range (-40°C to 125°C), making it ideal for automotive and industrial applications.
Multiple mounting methods allow for easy circuit integration – you can solder wires directly to the holes, use solderless ring terminals, or attach screw terminals. The largest holes accommodate wires up to 8 AWG and M3.5 screws, while additional 3.5 mm and 5 mm holes support screw connectors or header pins.
The module is ideal for applications requiring precise current measurement, such as energy management systems, battery monitoring, protection circuits, and industrial electronics. Its electrical isolation allows safe current monitoring in high-voltage systems, while its low power consumption makes it suitable for mobile and battery-powered devices. With a user-friendly interface and compact design, the sensor is an excellent choice for both professionals and hobbyists. It can be used in prototyping, testing, and as a component in fully developed measurement systems. The ease of integration and broad range of applications make the ACS71240 an essential tool in modern electronics.
