The TE Connectivity AMPMODU 1-104482-8 is a 40-position, dual-row receptacle housing built for the 2.54mm (0.100") pitch ecosystem — the workhorse pitch for ribbon cable, IDC, and discrete-wire harnesses across industrial controls, telecom racks, and automotive interior modules. It's a free-hanging (in-line) shell, meaning no board footprint to worry about — you terminate the wires with crimp contacts, stuff them in, and the housing becomes the connector body.
This housing ships empty. The note 'Contacts Not Included' is not a footnote — it's the main procurement action item. Without them, the housing is just a plastic shell. The crimp termination means you'll also need the correct hand tool or semi-auto applicator for the contact family. Plan the contact line item before the harness build starts.
Pitch and Row Spacing — Same Grid as Standard IDC
That means the 40-position housing mates directly with a 40-position, dual-row male header on the same pitch, no footprint mismatch. The 2-row layout keeps the connector width manageable for a 40-circuit harness: roughly 1.0" wide across the rows. If you're coming from a 30-position housing like the 1-2333134-5 (2.00mm pitch, 3.30mm row spacing), note the pitch difference — the 1-104482-8 uses the wider 2.54mm grid, which is more common for power and signal mixes in industrial gear.
