STAR-RING Snap Ferrite with Security Lock
STAR-RING snap ferrite sleeves from Wurth Elektronik feature a prefixing cable system that ensures a quick and easy cable assembly process. A security lock prevents unauthorised removal of the snap ferrite from the cable. The use of this key technology allows STAR-RING ferrite sleeves to be reusable, ideal for cables with difficult access or for test and measurement purposes. Suitable applications include external and internal computer power and data cables
Please note, the STAR-TEC key (74721) is sold separately. Refer to 815-0021 to order the key.

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.
