Piezo Cables

Piezo cable has a number of advantages in certain applications. Due to its coaxial design, the cable is self-shielded, allowing its use in a high EMI environment. The Piezo cable can be spliced to passive coax, using standard coax splice techniques. It is extremely rugged and will stand up to heavy loads. Its linear format makes it ideal for monitoring large areas. Two versions of the Piezo cable are offered, copolymer and spiral. With the copolymer version, a special version of the piezo material is extruded directly onto the inner conductor and then polarized. With the spiral wrap, strips of the PVDF film are double helically wound around the inner conductor. The copolymer is a much more expensive raw material and is available on a more limited basis than the standard PVDF.
