The TE Connectivity 1-1827863-3 is a 26-position receptacle housing from the Dynamic D-1100 series, built for wire-to-board or wire-to-wire harness applications where the 2.00 mm pitch keeps the board footprint tight without crowding out the crimp termination. It's the female side of the connection — you load it with the matching crimp socket contacts and mate it to a Dynamic D-1100 header.
You need to order the Dynamic D-1100 crimp socket terminals separately (TE part number 1-1827864-x, where x varies by wire gauge and plating). The housing accepts the female socket contacts that get crimped onto 20-24 AWG wire, then inserted into the cavities until the latch lock seats. Ordering just the housing and expecting a finished connector is the most common mistake on this line.
The 26 positions are arranged in two rows with a 2.00 mm pitch between contacts and a 3.30 mm row spacing. That row spacing gives enough room for the crimp barrels to sit side-by-side without the wires crowding at the back of the housing.
Latch Lock and Polarizing Key — Field-Mating Without Guesswork
The latch lock fastening type means the housing clicks onto the header with an audible snap — no screwdriver, no secondary clip. A half-turn loose isn't a concern here; the latch holds the pair mated under the vibration you'd see on a conveyor drive or a packaging line.
