Lightweight electromagnetic yoke
JAYMI Yoke
Description
The JAYMI is the next generation of yoke from Johnson & Allen – Developed to be light weight but powerful, efficient and robust. Previously customers have had to compromise on either weight, durability or power when choosing a yoke. Overcoming these limitations was the design philosophy behind the JAYMI.
The core is housed within an ergonomic injection moulded shell made from an abrasion and chemical resistant plastic and the yoke incorporates a number of rubber gaskets to retard fluid ingress. The energising micro switch is trigger mounted with a rubber membrane making it easy to press and giving a user friendly action to it.
Available in 230V and 110V versions.

*Note: The tangential extraneous magnetic field will vary depending on whether the yoke is energized in free space (unloaded) or when in contact with a part (loaded). Material properties and pole spacing will also alter the magnetic field. For this reason operators should not rely on field measurements alone as a performance check and should verify the lifting strength of the yoke with a 4.5kg test weight and use a QQI shim or flux indicator strip for evaluation before undertaking inspection.
