Fermacavo in ferrite DELOCK 80948, nero, nichel/plastica/zinco, 36 × 23,5 × 22,2 mm, confezione da 2

The DELOCK 80948 ferrite core clamp is designed to reduce electromagnetic interference (EMI) on round cables. Supplied as a pack of 2, each clamp features a clip-on design that closes around the cable to absorb and dissipate high-frequency noise. Constructed from nickel, plastic and zinc with a black finish and measuring 36 × 23.5 × 22.2 mm, the clamp helps improve signal integrity for audio, data and power lines where reduced interference is required.

Advantages

The clip-on ferrite core clamp provides an easy, non-invasive method to suppress high-frequency interference without cutting or modifying cables. Its compact dimensions and lightweight construction allow placement close to connectors or along cable runs, while the mixed-material build combines mechanical stability with effective EMI attenuation. Supplied as a pair, the product allows treatment of two cables or two points on the same cable as needed.

Suitable for

• Reducing EMI on audio cables to preserve sound quality
• Improving data signal integrity on USB, Ethernet or serial lines
• Suppressing interference on power leads to sensitive electronic equipment
• Industrial, office and home environments requiring electromagnetic noise reduction

Key specifications

• Material: nickel, plastic, zinc
• Colour: black finish
• Dimensions: 36 × 23.5 × 22.2 mm (per clamp)
• Design: clip-on ferrite core clamp for round cables
• Package contents: pack of 2 clamps

How to use

Open the clip-on ferrite clamp and place it around the cable at the point where interference reduction is required, then close the clamp until it snaps into place. For stronger suppression, position the clamp close to the connector or repeat placement at multiple points along the cable. The product does not require tools or permanent modification of the cable and can be repositioned as needed.

Recommendations

Place the ferrite clamp as close as possible to the device or connector where noise is introduced or where signal integrity is most important. Use one clamp per cable for moderate suppression or multiple clamps spaced along the cable for increased attenuation. Avoid mounting on flat ribbon cables not intended for round-core clamps.
