Description

Phoenix Contact 2203903 PCB headers have a nominal cross-sectional area of 2.5 mm² and are typically light gray in color, capable of handling a maximum current of 16 A at a rated voltage of 320 V (III/2). They feature a Sn contact surface, use pin connections with four potentials arranged linearly across one row of four positions, requiring four solder pins per potential, and have a standard connector pattern alignment. The headers are designed for wave soldering mounting and incorporate snap-in locking mechanisms to secure the connectors in place, without any additional packaging components.
