Cable type A09.x; part number CAC2P2FNP(1) is designed for sensor power and signal networks where the power and signal circuits are considered individual intrinsically safe circuits. The 4mm2 pair provides power to the sensor while the 1mm2 pair carries the output signal from the same sensor. The BMA cable consists of two main elements, an screened 4mm2 twisted pair and a screened 1mm2 twisted pair.
