TE Connectivity 3-Way IDC Connector Female Cable Mount 2.54mm Pitch 5A 250V ac MTA-100 Series 3-643815-3

TE Connectivity model 3-643815-3 is a 3-way IDC (Insulation Displacement Connector) female connector designed for cable mounting with a 2.54mm pitch and rated for 5A current at 250V AC. This connector belongs to the MTA-100 series, known for its ease of wire assembly, eliminating the need for stripping insulation thanks to its dual beam slotted IDC contacts. The housing is shrouded and made from durable nylon material, providing protection from accidental electrical contact and mechanical damage. Contacts are constructed from copper with a tin over nickel plating to prevent corrosion and ensure reliable conductivity.

The connector is designed with a right-angle orientation to support compact cable routing in constrained spaces typical in electronic assemblies. It operates reliably within a temperature range from -55°C to 105°C, making it suitable for demanding industrial environments. The friction lock mechanism and moulded ribs prevent reverse mating, ensuring secure and precise connector alignment.

Applications of this connector include automotive body and chassis systems, driver information systems, safety and security modules, desktop PCs, notebook computers, servers, storage devices, and workstations. The connector is stackable end-to-end, facilitating efficient mass termination in wire-to-wire or wire-to-board connections. This model supports wire sizes from 28 AWG to 22 AWG and can be quickly assembled using production hand tooling.

This IDC Connector enables one-step wire assembly without stripping insulation. Features a shrouded nylon housing to prevent accidental contact. Right-angle female connector orientation for space-efficient wiring. Copper contacts with tin over nickel plating resist corrosion.

Operates over a wide temperature range from -55°C to +105°C. End-to-end stackable with friction lock for secure connections. Suitable for automotive, computing, and consumer electronics systems. Part of the MTA-100 series 2.54mm pitch connector system.

This product is ideal for industrial, automotive, electronics manufacturing, and telecommunications applications requiring reliable and quick assembly of cable harnesses with durable, corrosion-resistant connectors.
