Board-fit and routing context
The SM05B-SURS-TF: The 4-wall shrouded housing protects the contacts from accidental shorting during handling and guides the mating receptacle into alignment, reducing pin stubbing.
Current and voltage ceiling
Rated 0.2A per contact with a 0.5A peak — this is a signal-level interconnect, not a power path. The 30V rating confirms it belongs in low-voltage logic or sensor circuits, not bus distribution. The tin-on-tin contact finish (mating and post) is adequate for occasional mating cycles in a controlled environment; if the application demands frequent disconnect or corrosive exposure, the gold-plated sibling SM05B-SURS-TF(LF)(SN) is the better choice.
