AC Electromagnetic Yoke 

The Y-2 is an AC electromagnetic yoke, ergonomically designed to improve productivity and reduce operator arm and wrist fatigue. The yoke generates a strong AC magnetic field for the detection of surface indications during magnetic particle testing.

Lightweight with an ergonomic grip and trigger, the Y-2 is designed for the rugged demands of field inspection. Featuring a field swappable cord and isolated trigger switch; the Y-2 is easily serviceable because a severed cord should not stop a job from getting done.

A super bright LED attachment is available as an optional item to help illuminate the inspection area while simultaneously magnetizing the part.


Increase inspector productivity and reduce physical fatigue 

  • Less arm strain, wrist fatigue and physical stress help operators get more done due to the lightweight and ergonomic design.
    Easily position the yoke in any direction with lightweight, heavy-duty and powerful electronics components.

Keep tools in service with a design that's built to last 

Cords and triggers can be easily replaced, so work doesn’t stop, and tools aren’t scrapped due to accidental damage.
Prevent dust and dangerous water damage with an IP54 O-ring sealed housing.
