A polarizing key prevents mis-mating, and the locking ramp provides positive retention once mated with the corresponding header.
This receptacle mates with SL-156 series headers that have a matching locking ramp feature. The crimp termination allows field-installable or harness-bench assembly using standard SL-156 crimp terminals (female socket). The polarizing key ensures the connector can only be inserted one way, reducing assembly errors.
