The 917745-1 is a 3-position header from TE's Power Double Lock series, with 2 positions loaded. The 6.50 mm pitch is unusually wide for a board-to-cable header — it sets a generous board footprint and allows higher per-contact current than a finer-pitch connector, though the exact current rating depends on the wire gauge used. Operating temperature range is -30°C to 105°C.
Partial position loading — confirm your circuit count
This header has 3 positions in the housing but only 2 positions loaded with contacts. The empty position is a keying feature — it prevents mating with a 3-circuit receptacle that expects all positions populated.
