40-position SMD header for board-to-cable harnesses
The 4-292229-0: This is a 40-position, dual-row shrouded header from TE's Mini CT series, designed for board-to-cable/wire applications. The 1.50 mm pitch sets the PCB footprint and the per-contact current ceiling — with tin-plated contacts, the current rating varies by wire gauge, so the limiting factor is the terminal crimp and wire size, not the header itself. The detent lock provides a positive latching feel when mated with the corresponding Mini CT receptacle, holding the connection against vibration in equipment cabinets or portable gear. A board guide on the housing assists alignment during SMD placement, reducing tombstoning risk.
Pitch, pinout, and mating half
The shrouded 4-wall design protects the male pins during handling and guides the receptacle into alignment — no keying, so the mated pair is orientation-sensitive only to the housing shape. Contact mating length is 0.114 inches (2.90 mm), and the SMD tails are tin-plated for solderability. The 2.90 mm mating length provides enough wipe for reliable contact in moderate-vibration environments, though the tin-on-tin interface limits mating cycles compared to gold-plated alternatives.
