0.100" pitch, 4-position single-row header with friction lock
The shrouded-1 wall guides the mating housing into alignment, and the friction lock provides retention without a secondary latch — adequate for low-vibration environments where the cable is not subject to constant flexing. For a connector that mates once at assembly and stays mated, tin is the practical choice.
The through-hole solder termination (contact length - post 0.135") suits wave-solder assembly.
Mating half and wire gauge flexibility
This header mates with any MTA-100 4-position receptacle housing (e.g., TE 3-647609-4's receptacle counterpart). For typical 22-24 AWG, expect 3-5 A per circuit in still air.
