Error graph

Influence of external magnetic field

CS09H-500A-C Series Closed Loop Hall current sensors use a very precise technology and provide customers with current measurement needs of applications.

In order to achieve this accuracy, some conditions must be observed when designing the sensor environment:

◆ Main busbar alignment

◆ Bus bar shape

◆ Contactor location

CAN output specification

◆ CAN protocol 2.0 A/B

◆ Bit order: big-endian mode (Motorola)

◆ CAN oscillator tolerance : 0.3125 %

◆ No sleep mode capability
