MY-2 Hand-Held AC Magnetic Inspection Yoke

Description

The MY-2 Hand-Held AC Magnetic Inspection Yoke is a lightweight, rugged and highly portable electromagnetic yoke designed for magnetic particle inspection (MPI) of ferromagnetic materials. It generates a powerful alternating current (AC) magnetic field to identify surface-breaking and near-surface discontinuities in welds, castings, forgings and other ferromagnetic components.

Designed for demanding industrial inspection environments, the MY-2 combines a durable encapsulated housing with an ergonomic comfort-grip handle and articulated adjustable poles. Its dual-length articulated legs allow the yoke to adapt to different component geometries and irregular surfaces, making it particularly useful for inspections in restricted-access areas and on-site applications.

Weighing approximately 2.2 kg, the MY-2 is an exceptionally lightweight inspection yoke. Its compact design allows comfortable one-handed operation, helping to reduce operator fatigue during extended inspection activities.

The MY-2 operates from a 110 VAC or 220 VAC mains supply and is supplied with a four-metre detachable power cable. The detachable cable design allows straightforward replacement if damaged, minimising equipment downtime and extending the service life of the instrument.

Suitable for use with both visible and fluorescent magnetic particles, the MY-2 provides a reliable solution for detecting surface and near-surface defects using magnetic particle inspection techniques. It can also be used for localised AC demagnetisation.

Designed to meet the requirements of BS EN ISO 9934-3 and ASTM E1444, the MY-2 is suitable for a wide range of industrial NDT applications where reliable magnetic field generation, portability and inspection flexibility are essential.
