TE Connectivity MTA-156 Series Straight Through Hole Pin Header, 2 Contacts, 3.96 mm Pitch, 1 Row, Unshrouded 640445-2

TE Connectivity presents the 640445-2 MTA-156 Series straight through-hole pin header, designed for robust wire-to-board applications in electronics and power systems. This pin header incorporates two contacts arranged in a single row, with a 3.96 mm pitch ensuring consistent spacing and facilitating easy integration into PCB assemblies. The unshrouded layout allows for end-to-end stacking and flexible placement within compact circuit designs.

Engineered for mass termination, the MTA-156 system leverages IDC (insulation displacement contact) technology, minimizing labor and reducing assembly time. With straight through-hole orientation, it offers reliable soldered connectivity and suits high-density PCB layouts. A friction lock mechanism is integrated into the header design, ensuring firm and secure mating with complementary female connectors and reducing the risk of accidental disconnection during operation.

The header is constructed using durable polyester housing and copper alloy contacts plated with tin, ensuring both electrical and mechanical stability across varied environments. It is rated for currents up to 7A and voltages up to 600V, supporting demanding industrial, automotive, and computer applications. The product is suitable for wire sizes ranging from 26 AWG to 18 AWG and offers a solder termination suitable for quick and robust installations.

Operating effectively between -55°C and 105°C, the MTA-156 header adapts to both low- and high-temperature environments. Applications include automotive body and chassis systems, safety and security electronics, industrial control panels, desktops, notebooks, servers, and consumer electronics where reliable PCB connections are essential.

Other technical highlights include a tail pin length of 3.18 mm, mating pin length of 10.16 mm, and a straight configuration supporting wire-to-board connection. All components meet relevant standards for industrial usage, though formal approvals or certifications should be obtained where specific regulatory compliance is required.

Widely adopted for cost-efficient mass termination and secure connection, this pin header exemplifies durability and performance in critical PCB interconnect scenarios across industrial and commercial sectors.
