Features and Benefits

Industrial and automotive customers need busbar current sensors with a reduced size and weight to make it easier to incorporate the device into miniaturized designs. Percept Current Sensors are more compact than competing products, improving design flexibility and enabling more efficient use of space in a variety of applications.

A high degree of accuracy is critical in many high-performance applications. Factory-calibrated Percept Current Sensors are extremely accurate to within +/- 2%, or within 0.5% for some products, making them ideal for sensitive electronics requiring consistent and accurate results.

Manufacturers want current sensors that are easy to install and that minimize assembly errors and downtime. The vertical-insertion design of Percept Current Sensors improves manufacturability and simplifies assembly, supporting automated manufacturing while avoiding the specific and demanding assembly requirements.

Significantly Smaller and Lighter Package

Percept Current Sensors use a vertically inserted coreless differential Hall-effect design and proprietary electronics packaging technology to provide accurate current sensing in an easy-to-install package up to 86% lighter and half the size of other busbar current sensors.
