Molex, a company specializing in electronics and connectivity, has launched its Percept Current Sensors, designed to meet the increasing demand for precise busbar current sensing in industrial and automotive sectors.
These sensors use Infineon’s coreless current sensor technology and Molex’s electronics packaging to reduce the size and weight of the sensors, while simplifying installation and integration processes.
The Percept Current Sensors feature a compact, coreless design, which Molex says makes them up to 86% lighter and half the size of comparable sensors. The sensors also aim to provide accuracy within 2% across a broad temperature range and lifespan, with low sensitivity and offset errors. Additionally, Infineon’s differential Hall-effect sensor design minimizes noise from stray magnetic fields, a common issue in industrial motor-drive and automotive applications.
Molex’s packaging technology integrates components such as high-current conductors, connectors and busbars into a single device, designed for high-temperature and high-current environments. The company says this technology supports system integration, enhances accuracy through precise chip placement and factory calibration, and accelerates assembly times.
The Percept Current Sensors are available in both industrial and automotive grades, with options for full-differential and single-ended output modes and bi-directional sensing. Operating temperatures range from -40°C to 125°C, in line with AEC-Q100 Grade 1 standards.
Industrial-grade sensors will be available in October 2024, with automotive-grade sensors expected in the first half of 2025. Limited engineering samples for industrial applications are currently available.
