Electro Magnetic Clamp

The CLEM-6146 Electromagnetic, or ‘EM’ Clamp is designed for use as a clamp injection device for conducted immunity tests in the frequency range of 150 kHz to 230 MHz according to IEC/EN 61000-4-6. The clamp can also be used for tests over its extended frequency range of 10 kHz to 1 GHz. The cable connected between the Equipment Under Test (EUT) port to be tested and its Auxiliary Equipment (AE) is placed into the EM Clamp. The EM Clamp provides a means by which RF energy is coupled onto the cable and decoupled from the AE path, so that the energy is directed toward the EUT. The CLEM-6146 incorporates split-core ferrites which allows the top half of the hinged enclosure to open so that the cable under test can easily be laid into position. Once closed, rotating the two knobs on the front of the clamp onequarter turn engages the locking mechanism which compresses the top and bottom halves of the ferrites together around the cable.

  • Frequency Range: 150 kHz to 230 MHz (extended range: 10 kHz to 1 GHz)
  • Designed for IEC/EN 61000-4-6
  • Extremely Efficient Coupling
  • Establishes both Capacitive and Inductive Coupling to the EUT Cable.
  • Three-Year Warranty
