Board-to-Wire Header for 0.156" Pitch Harnesses
The 1-640383-9 is a 19-position, single-row, unshrouded header from TE's MTA-156 series. Its 0.156" (3.96mm) pitch mates with the corresponding MTA-156 IDC or crimp receptacle to form a board-to-cable/wire connection. The UL94 V-0 glass-filled thermoplastic housing provides flame retardance for equipment inside an enclosure.
19 Circuits — an Uncommon Count for Single-Row Headers
Nineteen positions in a single row is a less common circuit count than 20 or 18. The 0.156" pitch means the board footprint is 19 × 3.96 mm = 75.24 mm wide, plus the keep-out for the unshrouded pins.
