The CMAD 1614 – Common Mode Absorption Device consists of many precision cut ferrite half-toroids, which are embedded in a grey plastic housing. The unique floating toroid bearing ensures a perfect fit of the ferrite surfaces. Two quick-locks at the long side allow opening and closing of the clamp within seconds. Cable bundles or coaxial cables with a maximum diameter of 26 mm are accepted by the clamp without disassembling connectors or interrupting any circuitry. The combination of short length and large cable hole diameter offer a broad variety of applications for the CMAD 1614. Each common mode absorption device comes with an individually measured calibration certificate.
The CMAD 1614 can be used for both, coaxial cables and unshielded cable bundles, in order to suppress unwanted common mode currents (also called braid currents). Since these unwanted common mode currents are very often a reason for poor repeatability of measurements, the new CISPR 16-1-4 standard recommends the use of absorbing clamps.
