Connectors with mismatched colours do not mate. Unique keying features within each header and receptacle housing prevent entry of receptacle into header when mis-mated. A positive lock feature produces an audible click when fully mated.
The absence of drain-holes in the PCB headers ensures compatibility with conformal coating (potting).
Kinked soldertails provide added header-to-PCB retention during solder reflow.
The headers are capable of 260°C wave-solder-processes and therefore ideally suited for high-temperature assembly processing.
