Product Description

TE Connectivity 3-640621-8 is an 8-way IDC female connector designed for cable mounting applications requiring a 2.54mm pitch and rated for 250V AC and 5A current. The connector belongs to the MTA-100 series and features a single row, shrouded nylon housing and phosphor bronze contacts plated with tin over nickel, ensuring durable electrical performance and mechanical reliability.

This IDC connector provides a right-angle orientation optimized for compact wire harness assemblies and mass termination processes. It supports fast and cost-effective assembly with insulation displacement contact technology, eliminating the need for wire stripping for 28 AWG to 22 AWG wire sizes or notched ribbon cable. Moulded ribs on the housing prevent reverse mating, enhancing assembly accuracy and consistency.

The connector operates reliably across a wide temperature range from -55°C to 105°C, suitable for demanding industrial and electronic component environments. It has no polarizing tabs, offering flexibility in mating, and uses standard 2.54mm centreline spacing.

MTA-100 IDC connectors are widely used in electronic components, power connectors, and cable assemblies for industrial, manufacturing, and electronic applications requiring robust and efficient wire-to-board and wire-to-wire connections.

This IDC connector supports quick and reliable insulation displacement termination. The shrouded nylon housing enhances durability and insulation safety. Phosphor bronze contacts with tin over nickel plating provide excellent conductivity and corrosion resistance.

Rated to handle operating temperatures from -55°C to 105°C for versatile use. The 2.54mm pitch single row layout ensures compatibility with standard wiring systems. Right-angle cable mount design facilitates convenient wire routing and space-saving assemblies.

Ideal for mass termination in industrial and electronic component manufacturing. Explore more electronic connectors and components with TE Connectivity's extensive range on EnvMart.
