MTA-100 IDC Plug, 3 Circuits, Tin Contacts
The TE Connectivity MTA-100 3-647000-3 is a 3-position IDC plug with male pins on a 0.100" (2.54mm) pitch, part of the MTA-100 series designed for discrete or ribbon cable terminations. This red housing accepts 22 AWG wire and terminates via insulation displacement, giving a gas-tight connection without stripping. Typical use is in internal harnesses, panel wiring, or board-to-wire links where a compact, one-row IDC connector fits the bill.
Termination and Wire Handling
This plug terminates with an IDC (insulation displacement) slot — you push the 22 AWG wire into the slot and the contact cuts through the insulation, no stripping or crimping needed. The closed-end design means the wire stops at the back of the slot, giving a consistent strip length. It works with discrete wire or ribbon cable, so it's a straight pick for a harness builder who wants one termination method across a few circuits.
Mounting and Mating
Free-hanging (in-line) mount with a right-angle orientation — the plug sits parallel to the board or panel face, useful in tight enclosures where a straight plug would hit the cover. Single-row layout keeps the footprint narrow.
