In the realm of printed circuit board (PCB) connector solutions, the 1-640456-8 model from TE Connectivity’s AMP Connectors MTA 100 series stands out as a robust, reliable choice for wire-to-board interfacing. Designed as a vertical PCB mount header, the 1-640456-8 accommodates 18 contact positions with a 2.54 mm (0.1 in) pitch, aligning with industry-standard spacing for smooth integration into a wide range of electronic assemblies. Engineered for through-hole soldering, this partially shrouded, tin-plated connector is tailored for solid interconnect performance where procurement reliability and seamless mating are critical to project success.

Main Architectural Attributes of 1-640456-8 MTA 100 Series

The 1-640456-8 MTA 100 series connector incorporates several structural elements that support its suitability for professional PCB designs. Its vertical orientation and wire-to-board system facilitate direct, space-efficient stacking, typically employed in control boards, modular units, and signal distribution panels. The single-row, 18-position configuration ensures straightforward routing and identification, minimizing design confusion during assembly and maintenance.

Polystyrene construction, paired with tin plating on contact areas, provides both mechanical stability and reliable conductivity over the lifecycle of the product. The partial shrouding adds an extra layer of protection, limiting accidental contact and enhancing physical guidance during mating. This configuration is optimal for environments demanding dependable engagement and resistance to handling errors.

Mechanical Properties and Environmental Suitability of 1-640456-8 MTA 100 Series

Mechanical reliability is a core focus of the 1-640456-8 model, facilitated by its robust header design and high-quality polyester material selection. The connector is supplied as an unshrouded unit with no special alignment features, offering flexibility in layout and minimizing manufacturing complexity.

Environmental resilience is delivered via adherence to RoHS and ELV guidelines, ensuring low hazardous material content. This compliance is crucial for build-to-market and export projects, particularly within EU jurisdictions or segments demanding green manufacturing protocols. Engineers can be confident that the component’s cadmium, lead, chromium, and other restricted substances are managed within specified limits, supporting both safety and regulatory conformity.
