Overview
CHCS-LFH-1005 series closed-loop high-precision Hall current sensor
Product Details
CHCS-LFH-1005Series closed-loop high-precision Hall current sensor（Instruction manual download:）
CHCS-LFH-1005The series sensor is based on the principle of closed-loop magnetic balanceMulti Hall, double-layer structure with high precisionHall current sensor,A true resolution of 1:1000. And it overcomes the errors caused by geomagnetic or line diameter thickness and position differences, with high accuracyMeasure DC, AC, pulse, and various irregular currents.

Structural diagram (mm)
Main tolerances:
·Total tolerance ± 0.5mm
·Install vertical positions with 4 holes of diameter 4.2mm and 2 holes of diameter 5.3mm
·Horizontal position with 4 holes and a diameter of 5.3mm
·Primary aperture 40.5mm * 38.5mm
·Connector MOLEX 5045-03A
usage method:
1.When IP flows in the direction of the arrow, IS is forward;
2.The temperature of the primary conductor should not exceed 100 ℃;
3. The optimal dynamic performance (di/dt and response time) is achieved when the mother row is fully filled with primary perforation;
4.To achieve optimal magnetic coupling, the primary wire turns should be wound around the top of the sensor;
5. Products can be customized according to customer requirements.
