What Is The Difference Between The Lemo® Type And The Coaxial Cables Used With Test And Measurement Microphones? |
|
Answer» A coaxial cable is designed to be used with an ICP® type prepolarized microphone or accelerometer. The coaxial cable houses a conductor enclosed within a shield (ground.) The CONNECTOR ends are generally BNC, SMB or 10-32 (microdot) CONNECTORS. A LEMO® cable is designed for externally polarized microphone applications. While the coaxial cables are very cost effective (typically, range ¼ to 1/10th the price of the LEMO® cables) and can be run long DISTANCES with minimal loss of signal, the LEMO® cables offer flexibility to carry multiple signals., The is necessary for 200V power supplies, mV output signals, and power for heaters, etc. For externally polarized applications, the most popular is a 7-pin LEMO® connector and cable.
