Board Fit and Pinout Match
Gold on the mating face means the contact interface resists fretting corrosion in environments with temperature cycling or vibration.
As an unshrouded header, it mates with any KK254-series crimp receptacle housing (e.g., 50-57 series) or a standard 0.100" pitch IDC socket.
Current and Environmental Limits
The glass-filled nylon housing handles the temperature range typical of these sectors. Per-contact current rating for the KK254 series with gold contacts is typically 2.5-3 A at 25°C ambient — derate above that. The unshrouded design means no polarisation keying; verify the mating half orientation before assembly.
