Under the same name you find totally different products ranging from cost effective D-Sub for basic industrial applications; stamped pins, flash gold plated, through hole …) up to really expansive ones with turned pins 0.76 µm gold plating, SMT…
Circular, rectangular and other typical military and aerospace dedicated connectors are not the main topic therefore they will not be detailed here.
