STAR-FIX LFS Split Ferrite Cores with Safety Lock

Wurth Elektronik STAR-FIX Snap Ferrites feature patented flexible cable fixing and the prefixing cable clamping system allows for easy assembly. The use of key technology ensures that STAR-FIX ferrite sleeves are reusable, making them ideal for cables with difficult access and test and measurement purposes.

Please note, the safety key (74271) is sold separately. Refer to 815-0021 to order the key.

These snap ferrite sleeves are suitable for suppression in the low frequency range between 300 kHz to 30 MHz. A typical application would be within the lighting industry, for suppression of electronic ballasts(neon tubes).

Patented technology

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.

Note

For cable diameter 4.5 → 8mm ( 736-1920 ) and 8.5 → 12.5 mm ( 736-1923 ). Weight 29g ( 736-1920 ) and 73g ( 736-1923 ).
