Formed / Deep Drawn Shields
Shields, Cans & Lids
High-Performance Magnetic Shielding Components for Sensitive Electronics
Comprehensive Magnetic Shielding for EMI Control & Signal Integrity
Manufactured from high-permeability NiFe soft magnetic alloys, our shields undergo advanced dry hydrogen annealing and are rigorously tested for magnetic and dimensional performance.
PML Precision Magnetic Shields Cans and Lids
PML's magnetic shields, cans, and lids are precision-engineered to protect sensitive electronic components from external magnetic and electromagnetic interference (EMI). PML performs controlled Dry Hydrogen Annealing: relieves internal stresses, re-aligns microstructure, restores magnetic permeability.
