What this 7-pin right-angle header does in a board-to-cable link
The 3.50mm pitch gives you more room between traces than a 2.54mm header, which helps when routing higher-current circuits on the PCB.
Pitch, orientation and board footprint
The 3.50mm pitch is the first dimension you check for board layout: it sets the pad spacing and the minimum trace width between pads. At this pitch, the header can carry more current per circuit than a 2.54mm header because the wider spacing reduces mutual heating and allows larger PCB traces. This saves z-height inside the enclosure and is the natural choice for board-edge connectors where the harness routes along the panel wall. The post length is 0.126" (3.20mm) — a standard through-hole length that fits most 1.6mm PCBs with room for the solder fillet on the opposite side.
Temperature range, flame rating and housing material
The LCP housing holds its dimensional stability across this range — important for maintaining contact alignment in the mated pair. UL94 V-0 flame rating means the housing material stops burning within 10 seconds after the flame is removed, with no burning drips. This is a requirement for connectors inside enclosed equipment where fire spread must be contained to the source.
