Overview

The 3-643814-2 is part of the TE Connectivity MTA-100 (Mass Termination Assembly) series, designed for high-density wire-to-board connections. It features a 2.54mm (0.100 inch) pitch and utilizes Insulation Displacement Contact (IDC) technology to allow for rapid, reliable termination without stripping individual wires. This specific receptacle is color-coded for use with 24 AWG discrete wire or notched ribbon cable.

Why Choose This Part

The MTA-100 system significantly reduces labor costs by eliminating the need for wire stripping and individual crimping. It features a locking ramp for secure mating and is constructed from UL94V-2 rated nylon with tin-plated copper alloy contacts for cost-effective reliability. The series is keyed to ensure correct polarization and prevent accidental misalignment during assembly.

Applications

Internal Signal Routing
Connecting sensors or switches to control boards within industrial or consumer enclosures.
Power Distribution
Low-current DC power delivery for peripheral modules in modular electronics.
Ribbon Cable Termination
Mass termination of 0.100 inch pitch ribbon cables for simplified assembly in multi-wire systems.
Prototype Interconnects
Providing secure, locking connections for internal modules that require more vibration resistance than standard friction-fit headers.

Also Consider

MTA-100 2-Pos Receptacle (22 AWG) TE Connectivity - Use this variant if your application requires the higher current capacity or mechanical strength of 22 AWG wire.
MTA-100 2-Pos Receptacle (26 AWG) TE Connectivity - Select this version when working with thinner 26 AWG signal wires to ensure a proper IDC gas-tight seal.
