Percept Current Sensors leverage Infineon’s high-precision coreless current sensors and Molex’s proprietary electronics packaging technology to further reduce sensor size and weight while simplifying installation and system integration significantly.
The compact, coreless design and electronics packaging of the Percept Current Sensors results in a solution that is 86% lighter and up to half the size of competing current sensors. This enables higher-density packaging within devices, which contributes to reductions in overall system weight while facilitating greater design flexibility.
Molex’s Percept Current Sensors offer increased sensing opportunities in space-constrained applications as well as those sensitive to electromagnetic interference (EMI). They also provide accuracy within 2% across a wide temperature range and entire product lifespan, along with low sensitivity and offset errors. Additionally, Infineon’s differential Hall-effect sensor design suppresses noise from stray magnetic fields, which are commonly found in demanding industrial motor-drive and automotive applications.
Molex’s proprietary electronics packaging technology enables seamless integration of high-current conductors, connectors, Printed Circuit Boards (PCBs), busbars, and heat sinks, among other mechanical components, into a single device. This capability is highly suited for assemblies that must withstand high temperatures, high currents and harsh environments.
Percept Current Sensors take advantage of this proprietary packaging method to ensure flexible system integration and boost accuracy from precise chip placement and factory calibration. Pre-calibrated systems not only lead to simpler, streamlined installation, but also can dramatically speed assembly time.
This novel packaging technology uses 99% less water than typical PCB manufacturing and does not require any chemicals or generate copper sludge, enabling a more environmentally friendly manufacturing method. Versatile and configurable design options, including the sensor-in-busbar design, provide customers with a complete package for plug-and-play deployments that do not require excessive development time, resources or cost.
Percept Current Sensors are available in industrial- and automotive-grade options, encompassing full-differential and single-ended output modes and bi-directional sensing. Available current ranges include +/-450.0 to +/-1,600.0A; operating temperatures extend from -40 to 125°C in accordance with AEC-Q100 Grade 1 standards.
Sensors for industrial applications are slated for October 2024 availability, followed by automotive application product approval process planned for the first half of 2025.
Limited engineering samples for industrial applications are now available.
