Board-edge wiring without the shroud
The unshrouded design means there's no polarisation key — the mating connector must align manually, which works fine in accessible, low-vibration harnesses but adds risk in blind-mate or high-shock environments.
Tin-plated contacts and UL94 V-0 housing
This is a standard tin finish — adequate for general-purpose use but not rated for high-mating-cycle or corrosive environments. The voltage rating is 250 VAC, which is typical for signal-level and low-power circuits in this pitch class.
