Magnaflux Y-2 AC Electromagnetic Yoke Kit – 115V

The Magnaflux Y-2 AC Yoke Kit is a complete, field-ready magnetic particle inspection kit built around the industry-leading Y-2 electromagnetic yoke. Ergonomically designed to reduce operator arm and wrist fatigue, the Y-2 generates a strong AC magnetic field for reliable surface indication detection — all in a lightweight, IP54-sealed housing built for the rugged demands of field inspection.

The field-swappable power cord and replaceable trigger switch mean a severed cord won’t take a yoke out of service. Everything ships in a rugged carrying case.

Kit Contents

  • Magnaflux Y-2 AC Electromagnetic Yoke (115V): Lightweight, ergonomic yoke with articulating legs and field-replaceable power cord
  • #1 Gray Magnetic Powder (1 lb.): High-contrast dry method powder for detection on dark or standard metal surfaces
  • #8A Red Magnetic Powder (1 lb.): Sharp contrast on light-colored or shiny metal surfaces
  • Paint Marker: For marking and documenting discovered indications
  • Cleaning Rag: For quick cleanup of hands and equipment in the field
  • Rugged Carrying Case: Durable, organized case to protect the yoke and keep consumables secure during transport

Key Benefits

Increase Inspector Productivity & Reduce Fatigue

  • Lightweight, ergonomic design reduces arm strain, wrist fatigue, and physical stress for longer inspection shifts
  • Easily position the yoke in any direction with lightweight, heavy-duty electronics components

Built to Stay in Service

  • Field-swappable power cord and replaceable trigger switch — accidental damage won’t scrap the tool
  • IP54 o-ring sealed housing prevents dust and water damage in harsh field environments

Features

  • Ergonomic Lightweight Design: Reduces operator fatigue during extended inspection shifts
  • IP54 Sealed Housing: Resists dust and water ingress for reliable field performance
  • Field-Swappable Power Cord: Replace in the field without tools — keeps jobs moving
  • Isolated Replaceable Trigger Switch: Serviceable in the field for maximum uptime
  • Steel Leg Shields: Protects articulating legs from impact damage
  • Exceeds ASTM E1444 Lifting Specifications: Certified lifting force for compliant AC MPI inspections
  • Optional LED Yoke Light: Longer-lasting, more intense illumination vs. traditional bulbs for improved indication visibility
Pro NDT Tip

Verify Lift Force at the Start of Every Shift: Per ASTM E1444, AC yokes must demonstrate a minimum 10 lb (4.5 kg) lifting force before use. Test your Y-2 with a Magnaflux Certified Yoke Test Weight (PN 624115) at the start of each shift and after any drop or impact. Place the yoke legs at the maximum pole spacing you intend to use — if it passes at maximum spacing, it passes at all shorter spacings. A yoke that fails the lift test must be removed from service immediately.

Applications

  • Surface defect detection on welds, castings, forgings, and machined components
  • Field and in-service MPI inspections with AC power access
  • Aerospace, automotive, pipeline, and structural inspection
  • Dry method MPI using #1 Gray or #8A Red magnetic powders

OPERATION

1. Attach power cord, making sure connection is secure. Connect the power supply to line power.

2. Position yoke legs at right angles to the direction of suspected discontinuities. Adjust legs as needed for best contact with surface.

3. Depress trigger to energize yoke. Apply magnetic particles to area between legs. While energized, blow off excess powder to reveal indications.

4. Evaluate indications for size, shape, and relevant locations.

5. Reposition yoke legs at 90-degrees to previous position and repeat steps 2-3 to reveal indications in all directions.

6. Demagnetize by slowly withdrawing yoke from surface, up to 18 in / 45 cm distance, while yoke is energized.

7. OPTIONAL YOKE LIGHT: To install, slide over the rear leg with LEDs facing in. Push up onto the housing until tabs are secured. Yoke light will automatically operate when yoke is energized. To remove, pull sides out and down to disengage tabs, then slide off. No tools are necessary for installation or removal.

MAINTENANCE

  • Use mild soap and a damp cloth to clean the yoke housing
  • Do not immerse any part of yoke in liquid
  • Legs may be detached at the joints for cleaning
  • Use a rust-preventative spray (LPS-3 or equivalent) on legs for lubrication

Frequently Asked Questions: Magnaflux Y-2 Magnetic Particle Yoke

Q: What is included in the Magnaflux Y-2 Yoke Kit versus the standalone unit?

A: The Y-2 Yoke Kit is a complete, "out-of-the-box" inspection solution housed in a rugged carrying case. In addition to the Y-2 AC Yoke, the kit includes #1 Gray and #8 Red Dry Magnetic Powders, a paint marker, and wiping cloth for cleanup. This kit is designed for field technicians who need a portable, organized setup for moving between job sites without carrying loose containers of consumables.

Q: What is the lift capacity of the Magnaflux Y-2 Yoke?
A: The Y-2 AC Yoke is designed to meet and exceed industry specifications. It provides a lifting power of at least 10 lbs (4.5 kg) at a 4-inch to 6-inch pole spacing, which is the standard requirement for AC yokes under ASTM E1444 and ASME Section V. To verify your yoke’s performance in the field, we recommend using a certified 10 lb. AC Test Weight.

Q: Can the Y-2 Yoke be used for both Dry and Wet Method inspections?
A: Yes. The Y-2 is highly versatile. It can be used with Dry Magnetic Powders for rough surface inspections or with Fluorescent Wet Method aerosols for high-sensitivity detection of fine surface cracks.

Q: How do I verify the magnetic field strength of the Y-2 Yoke during an inspection?

A: To ensure you are achieving proper magnetic field direction and strength on the part surface, you should use a Pie Gauge or Magnetic Field Meters. These tools are placed on the workpiece while the Y-2 is energized to provide a visual verification that the magnetic field is adequate for the specific orientation of the suspected defects.

Q: Is the Y-2 Yoke cord replaceable?
A: Yes. One of the primary design improvements of the Y-2 over the older Y-1 model is the field-replaceable power cord. If the cord becomes frayed or damaged during heavy use, you can easily swap it out without having to replace the entire unit or send it in for extensive electrical repair. In addition, the Y-2 yoke features an isolated switch housing making switch replacement simple and fast without comprimising the yoke IP rating.

Q: What is the benefit of the Y-2’s articulating legs?
A: The articulating legs allow the operator to adjust the contact footprint to fit the geometry of the part. This is essential for inspecting welds in corners, on curved pipe surfaces, or on irregularly shaped castings where a fixed-leg yoke would fail to make proper magnetic contact.
