40-position dual-row footprint for board-to-board or cable mating
The gold layer buys you 500+ mating cycles in a production or test-fixture environment — the tin post finish (150 µinch) on the solder tail handles the wave-solder side without issue.
Push-pull fastening and through-hole solder termination
Fastening is push-pull — no latch or lock. In a low-vibration bench or rack application this is fine, but for mobile or high-shock environments you'll want to pair it with a header that has a friction-lock or use a secondary retention method. Termination is through-hole solder. The post length is 0.125" (3.18 mm) — standard for a 0.062" board with wave or selective solder.
