High-Precision Current Sensors Target Automotive, Industrial Busbars
Connectivity company Molex partnered with Infineon to create a new line of high-precision coreless current sensors to meet the demand for accurate busbar current-sensing solutions in automotive and industrial applications. The new Percept Current Sensors take advantage of Infineon's coreless sensors and Molex's electronics packaging technology to reduce sensor size and weight, facilitating installation and system integration.
"The new Percept Current Sensors benefit from Infineon's coreless sensor and our proprietary electronics packaging technology to set new standards for current-sensing accuracy, reliability, and integration simplicity," stated Lily Yeung, director of Sensors and Transportation Innovative Solutions at Molex. "Together, we can save customers valuable space and optimize product performance while reducing major design and manufacturing complexities and costs."
The Percept Current Sensor series features a coreless differential Hall-effect design that suppresses stray magnetic fields, providing low sensitivity and offset errors. They’re also accurate to within 2% across a wide temperature range, suiting them for harsh environments. The sensors feature a 450- to 1600-A current range, a 4.5- to 5.5-V supply range, and an AEC-Q100 operating temperature range of −40 to +125°C.
According to Molex, the Percept Current Sensors are available in industrial and automotive-grade options. Sensors for industrial applications were slated for release in October 2024, while the automotive application product approval process is scheduled for the first half of 2025.
