Clipe para núcleo de ferrite DELOCK 80945, preto, níquel/plástico/zinco, 16,5×30×14 mm, pack de 2

The DELOCK ferrite core clamp is a two-piece clamp-style suppressor designed to reduce electromagnetic interference (EMI) on round cables. Each compact unit is made from a combination of nickel, plastic and zinc and clips around a cable to absorb and dissipate high-frequency noise that can degrade signal integrity. The clamp-form factor allows simple retrofitting to existing power, data and audio/video lines without disconnecting equipment.

Advantages

This ferrite clamp provides passive EMI suppression across a broad frequency range by increasing impedance to unwanted high-frequency currents. Its snap-on design enables quick installation and removal for testing or repositioning. The mixed-material construction balances mechanical strength with effective magnetic properties, helping to stabilize signal quality in sensitive applications. Supplied as a pack of two, it allows protection of multiple cable runs or both ends of a single cable where needed.

Suitable for

• Power cables and AC adapters where conducted interference affects connected equipment
• USB, HDMI, Ethernet and other data lines to improve data transmission reliability
• Audio and video cabling to reduce hum, hiss and high-frequency artifacts
• Laboratory and measurement setups requiring reduced electromagnetic noise
• Industrial and office environments with multiple nearby electronic devices

Key specifications

• Form factor: snap-on clamp, two-piece construction for easy attachment
• Materials: nickel, plastic and zinc for mechanical durability and magnetic behavior
• External dimensions: approximately 16.5 × 30 × 14 mm per clamp
• Color: black, suitable for unobtrusive installation
• Pack contents: two identical ferrite clamps for multiple uses

How to use

Open the two-piece clamp and place the cable centrally in the clamp channel, then close until it snaps shut around the cable. For best suppression of common-mode noise, position the clamp close to the interference source or the equipment connector; multiple clamps may be used along a cable or at both ends for increased effectiveness. No tools are required for installation and the clamp can be removed or relocated without altering the cable.

Recommendations

Use the ferrite clamp on single round cables; avoid forcing over large or flat cables not matching the clamp channel. For critical signal lines, test placement by moving the clamp along the cable to identify the position that yields the greatest improvement. Do not expose the clamp to corrosive chemicals or excessive mechanical stress.
