Molex shrinks busbar current sensors

Percept current sensors from Molex employ a coreless differential Hall-effect design and proprietary packaging to slash both size and weight. The sensor-in-busbar configuration allows for simple plug-and-play installation in automotive and industrial current sensing applications, such as inverters, motor drives and EV chargers.

Percept integrates an Infineon coreless magnetic current sensor in a Molex package to create a component that is 86% lighter and up to half the size of competing current sensors. The design also suppresses stray magnetic fields and reduces sensitivity and offset errors. 

Automotive and industrial-grade Percept sensors are available in current ranges from ±450 A to ±1600 A, with ±2% accuracy over temperature. They offer bidirectional sensing with options for full-differential, semi-differential, and single-ended output modes. AEC-Q100 Grade 1-qualified devices operate across a temperature range of -40°C to +125°C.

Sensors for industrial applications are expected to be available in October 2024, with the automotive product approval process scheduled for the first half of 2025. Limited engineering samples for industrial applications are available now.
