Magnaflux 625643 Electromagnetic Yoke Ac Dc 115V Type B

Product Description

The MAGNAFLUX 625643 is a heavy-duty AC/DC electromagnetic yoke built for magnetic particle inspection of ferromagnetic components in demanding field and shop environments. Operating at 115 volts, 50/60 Hz, this Type B yoke uses solid-state controls to switch between AC magnetic fields for surface-breaking indications and DC magnetic fields for sub-surface indications. The sealed, chemical-resistant housing and articulating legs allow the unit to conform to irregular part geometries, while a 12-foot strain-relieved cord supports remote and field-based inspection work. Licensed NDT technicians and quality-control inspectors rely on this yoke for fast, reliable magnetic particle testing.

The 625643 is suited for both in-service and new-construction inspections across industrial, petrochemical, and structural fabrication settings. Typical applications include weld inspection, spot checks on in-service components, and systematic inspection in demanding outdoor or confined-space environments. The articulating pole design accommodates flat surfaces, pipe welds, curved castings, and other irregular geometries without requiring additional adapters. It is well-suited for field inspection crews who need a self-contained, portable yoke that meets multiple standard requirements in a single unit.

Key Features

• AC mode detects surface-breaking indications; DC mode detects sub-surface indications
• Sealed, chemical and abrasion-resistant construction for rugged field use
• Articulating legs conform to flat, curved, and irregular part shapes
• 12-foot strain-relieved cord designed for remote and outdoor inspection
• Exceeds ASTM lifting force specifications for magnetic yokes
• Individual serial number on each unit for traceability and calibration records

Compatibility

Designed for use in magnetic particle inspection applications on ferromagnetic materials requiring compliance with ASME BPVC, ASTM E709, ASTM E1444, ASTM E3024, and ISO 9934-3 inspection standards.

Installation Notes

This yoke is installed and operated by qualified NDT technicians holding appropriate magnetic particle testing certifications. Before use, verify the power source matches the 115-volt, 50/60 Hz rating and inspect the strain-relieved cord for damage. Ensure the component under test is properly cleaned and that all adjacent personnel are aware when the magnetic field is energized. Follow the applicable inspection procedure and written practice per your governing code or standard before beginning any examination.
