Phoenix Contact 5452500 The PCB header features a nominal cross-sectional area of 2.5 mm² and has a black color. It's designed to handle a maximum current of 12 A at a rated voltage of 320 V. The headers have a standard contact surface made of Sn (tin) and utilize pin contacts, with ten potentials across one row of ten positions. These headers are mounted using wave soldering techniques and follow a linear pinning layout. Each solder pin is approximately 3.9 mm long, with a single solder pin per potential. They come in a BASICLINE 2.5 pin connector pattern and are secured by screw locking mechanisms with threaded flanges, packaged in cardboard.
