Zero Gauss P

P­-TYPE SEMI­-CLOSED CYLINDER SOFT FERROMAGNETIC SHIELD

The P-­chamber is a soft ferromagnetic shield featuring superior material characteristics such as high linearity, very low hysteresis, and high magnetic permeability.

Description

The chamber is designed for protecting sensitive circuits from unwanted parasitic magnetic fields. Applications include power inverters, magnetic sensors, magnetic immunity, and EMI.
