Features

Magnetic properties guaranteed during mass production

・Coercive force standardized, magnetic properties after annealing guaranteed for the lot

・Coercive force inspection also performed at shipping inspection

Magnetic and electrical characteristics support

・SHT supports all required test measurements (0 – 1600 A) with our magnetic and electrical characteristics measurement environment.

　Magnetic properties: Residual flux densty(Br), saturation (B-H characteristic), linearity

　Electrical properties: Withstand voltage test of fully moldings

To get the most out of magnetic current sensor, it’s important to select the optimal product while taking into consideration the performance of the core and shield.

By proposing our Melexis current sensors together with SHT cores and shields, we can eliminate the need for component research, reduce the risk of mismatching the current sensor with the core or shield, and provide the optimal solution for your application.

Sensor Cores

Wound core

・Wound by our proprietary automatic winders for shapes with no line overlap

・Optimized temperature profile ensures excellent magnetic properties

Laminated core

・Non-oriented high-grade material is used to achieve the desired characteristics and cost performance

・Optimized temperature profile ensures excellent magnetic properties

Partially molded core

・Partial molding eliminates metal burrs

・Dimensional precision ideal for casing and molding

Fully molded core

・High quality and low cost achieved by automated production from core to fully molding

・Zero defects in products marketed

Casing core

・Ultrasonic welding eliminates degradation (of 20% or more) due to molding stress while achieving fundamental core properties

・High quality and low cost achieved by automated production from core to case
