TWM 220 N

Electromagnetic Yoke

Our TWM yokes are the perfect mobile crack detection units, particularly for checking ferromagnetic parts where burn marks and annealing must not occur. These durable AC electromagnetic yokes are designed to detect surface indications.

The TWM 220 N yoke can be connected directly to a 230V AC supply. When used with our adjustable pole pieces, it is ideally suited for testing uneven surfaces, tube bends, angle pieces, etc.
