Y-1 - Discontinued

AC Electromagnetic Yoke

Discontinued and replaced by the Y-2 Yoke

The Y-1 is an AC electromagnetic yoke and the new generation of light weight, ergonomically designed yokes that improve job performance and productivity by reducing operator arm and wrist fatigue when testing in tight, confined and overhead areas. Provides a portable means of creating AC magnetic fields for the detection of surface indications during magnetic particle testing.

Lightweight, less than five pounds, and ergonomic with a molded grip and trigger on/off switch, the Y-1 has impact and chemical-resistant construction. Includes a robust strain-relieved ten-foot cord and carrying grommet for convenience in field use.

Benefits & Features

  • Ergonomic, light-weight design
  • Soft-grip, angled body for better positioning
  • Exceeds ASTM lifting specifications
  • Steel shields for leg protection
  • Durable rugged construction
  • Oil and abrasion resistant power cord
  • Individual serial number for each yoke
