Product Details
Split Ferrite Rings
These split ferrite cores reduce the electromagnetic interference from being induced in or radiated from data and power cables. High attenuation ratings are achieved with the housing design and the special process steps during the ferrite manufacture. The special snap lock makes the ferrite sleeve suitable for use with a variety of cable diameters and once the split ferrite is locked it cannot be opened accidentally.The outer housing is designed to protect the halves of the core from breakage and ensures simple assembly on to cables that are already installed or which have been fitted with connectors. Fixing to the cable with glue or cable tie is optional. Typical applications for these split ferrite cores include data or power lines used in computer technology, terminals, industrial controllers, medical engineering and office machines.
Ferrite Sleeves Accessories
Wurth Elektronik offer accessories that are specially designed for their ferrite sleeves.
The safety key can be used to unlock and lock the ferrite sleeve. The use of key technology ensures that the ferrite sleeves are reusable and that only authorised parties can unlock the snap ferrites.
STAR-CLIP from are designed for use with STAR-TEC and STAR-FIX snap ferrite sleeves. Constructed from UL94-V0 plastic, these clips require prefixing on to the ferrite sleeve.
