Essentra Openable Ferrite Sleeve, 19 x 20.8mm, For EMI Suppression, Apertures: 1, Diameter 8.5mm

From Richco, these snap-fixing ferrite cores are designed to attach to cables in order to reduce electromagnetic interference from being induced or radiated. The ferrite is housed in a hinged nylon 66 carrier, which is simply snapped around cable and is supplied with a cable tie which can be used to prevent the ferrite sliding along cable when attached to the integral retaining lug.

• Rectangular ferrites are suitable for data cables e.g. telephone or signal lines.
• Circular ferrites are suitable for mains cables e.g. on photocopying machines, printers and other office equipment.

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.
