Product details

Board-to-wire header with friction lock

The 3-644861-1 is the 11-position member of TE's MTA-100 shrouded header line, designed for board-to-wire applications with a friction lock that holds the mating receptacle in place. Its single-row contacts are on a 0.100" (2.54mm) pitch, rated 250VAC, and use tin-plated mating surfaces for cost-effective signal duty.

Position count and series fit

Within the MTA-100 series, the 3-644861-1 carries 11 positions in a single row at 0.100" (2.54mm) pitch — the friction lock and 4-wall shrouding are shared across the series, so the position count is the selection variable.
