2 A Per Contact — Signal-Duty Ceiling, Not Power
The 2 A limit keeps the temperature rise inside the UL94 V-0 thermoplastic housing within safe margins. For a typical digital I/O or low-current analog signal, the current draw per pin is well under 500 mA, so the derating headroom is generous.
Through-Hole Termination — Board Retention Without Adhesive
The 0.335" overall contact length includes a 0.157" mating pin — enough to engage a standard receptacle without bottoming out.
