Planar induction

■ Reluctance switch products

The AMR bridge resistance, which changes in impedance value depending on the strength and Angle of the
parallel passing magnetic field, is integrated with the ASIC in a single chip. Non-contact position detection is carried out by matching with magnet. Compared with Hall sensor, it has higher accuracy (the return difference can be less than 3 Gauss), parallel induction to magnetic field, and achieves 360 degree two-dimen-sional induction with AWR bridge resistance in different directions. Mainly used in different induction Angle and ground high frequency induction applications, there are two product lines, one-dimensional induction switch and two-dimensional induction switch.

Reluctance one-dimensional induction switch

Built-in single AMR bridge resistance, to achieve the detection of magnetic field within an Angle of ±25° It is typically used for accurate detection where remanence interference is required.

Recommended application: Industrial cylinder stroke position detection, intelligent water meter and gas meter flow count and anti-magnetic attack detection.

■ Current sensor module

The CC921 product family is an open-loop current sensor module based on the Hall effect principle, which
can be used for AC or DC detection in a wide range of industrial, commercial and communication systems.
Each CC921 consists of a high precision, low noise, low temperature drift linear Hall IC, magnetic core, and built-in current conductor path with low insertion resistance. The applied current flowing through the path of a low-resistance current conductor creates a magnetic field, which the chip converts into a voltage signal output proportional to the input current. Because of the use of magnetic core inside the module, it can effectively suppress the interference of external common mode magnetic field to the module, and improve the accuracy in the magnetic field environment.
