CDN 500 Coupling Clamp

The CDN 500 coupling clamp is manufactured exactly according to the drawings and specifications of ISO 7637-3 for capacitive coupling of transients on cables and cable harnesses. The CDN 500 coupling clamp with a characteristic impedance of 50 Ω is connected to the generator via a coaxial cable and terminated on the far side with a 50 Ω load resistor. A suitable terminating load is available as an accessory under type number INA 5030, which also provides a measurement output via a 40 dB attenuator. The coupling terminal is suitable for ribbon cables and round cables up to 40 mm diameter. The effective coupling capacitance depends on the cross section and material of the cable used; a typical value is approximately 100 pF.
