Magnaflux 1848 Replacement Copper Braid Contact Pad
The Magnaflux 1848 is a high-grade copper braid contact pad designed to provide reliable electrical contact between the test part and the contact head on wet bench MPI equipment. Measuring approximately 4.75" (120.65 mm) × 7.5" (190.5 mm), this pad is a direct replacement for part numbers 18948 and 18949 contact pad assemblies.
Magnaflux uses high-grade copper alloy construction to deliver superior conductivity, maximum durability, and consistent arc prevention — protecting test pieces from burning during magnetization.
Key Features
- Arc & Burn Prevention: Copper braid construction distributes current evenly across the contact surface, preventing arcing and burning of test pieces
- Reversible Design: Two wear faces double the service life of each pad — simply flip when one face is worn
- Flexible Construction: Conforms to the part surface for maximum contact area and consistent magnetization
- High-Grade Copper Alloy: Superior conductivity and durability vs. standard contact pads
- Direct Replacement: Replaces pads for Magnaflux part numbers 18948 and 18949
Inspect Your Contact Pads Before Every Shift: Worn, contaminated, or damaged contact pads are one of the most common causes of arc burns on test parts — which can create stress risers and cause part rejection. Check pads for embedded metal particles, thinning, or uneven wear before each inspection shift. Flip to the second wear face when the first shows significant wear, and replace the pad entirely when both faces are degraded. Clean pads with a wire brush to remove embedded particles and restore conductivity.
Applications
- Wet bench MPI equipment contact head replacement pads
- Direct contact magnetization of ferromagnetic parts
- High-volume production MPI inspection lines
- Aerospace, automotive, and heavy industry wet bench inspections
