PCB Mount Header, Right Angle, Wire-to-Board, 36 Position 1-5174912-2

Product Description

When engineering complex electronic assemblies, the integrity of signal transmission and power distribution relies entirely on the physical connections bridging the circuitry. The 36-Position Right Angle PCB Mount Header (Part Number: 1-5174912-2) serves as a foundational component for these critical junctions. Sourced directly as an authentic Tyco (TE) brand component, this header guarantees absolute genuine traceability, immediately eliminating the compliance and performance risks associated with unverified components in rigorous procurement cycles. Holding this component, one immediately notices the rigid, dense structure of the black thermoplastic housing, designed to withstand the mechanical stresses of both automated assembly and long-term operational vibration. It is not merely a connector; it is a meticulously engineered interface designed to ensure that every wire-to-board transition remains secure, stable, and electrically flawless under continuous operational strain.

Structural Integrity and Foolproof Assembly

The physical architecture of this PCB mount header is optimized for error-free installation and long-term mechanical stability. Featuring a fully shrouded design, the rigid outer walls encapsulate the delicate internal contacts, providing a robust physical barrier against accidental bending, dust ingress, and impact during handling. The right-angle, double-row configuration houses 36 distinct positions, offering an excellent balance between spatial efficiency on crowded printed circuit boards and comprehensive signal routing capabilities. Furthermore, the inclusion of built-in PCB mount alignment and mating alignment features acts as a tactile guide during the assembly process. Operators and automated insertion machines receive immediate physical feedback—a distinct mechanical seating sensation—that prevents blind mating errors, misalignments, and the costly rework associated with bent pins. The 2.5 mm [0.098 in] centerline pitch ensures adequate electrical clearance while maintaining a highly efficient footprint.

Advanced Metallurgy and Environmental Resilience

At the core of any reliable electrical interface lies its contact metallurgy. This header utilizes a sophisticated composite plating strategy in its mating areas, combining the distinct advantages of Gold (Au) and Tin (Sn). The gold plating provides an exceptionally smooth, oxidation-resistant surface that guarantees low-resistance signal pathways, which is crucial for sensitive data transmission without signal degradation. Simultaneously, the tin plating enhances solderability, ensuring that the through-hole screw termination forms a structurally sound and electrically conductive bond with the printed circuit board. Beyond the metals, the entire assembly is engineered for severe environmental conditions. Capable of operating flawlessly across a wide temperature gradient from a freezing -30°C up to a blistering 105°C (-22 to 221°F), the selected materials resist thermal expansion and contraction. This thermal stability prevents microscopic fractures in the solder joints, ensuring the connector maintains its integrity even when subjected to the harsh, fluctuating climates of vehicle engine compartments or outdoor industrial enclosures.

Production Line Compatibility and Broad Applications

Efficiency on the manufacturing floor is directly tied to how components are delivered and handled. This header is supplied in standard tube packaging, a method specifically chosen to protect the precise geometry of the tab contacts while perfectly accommodating automated pick-and-place machinery. The smooth, anti-static tubes allow the components to slide seamlessly into feeder mechanisms, dramatically increasing assembly throughput and reducing manual handling risks. Once on the board, the through-hole board mount design is fully compatible with standard wave soldering processes. Because of this rigorous quality control and adherence to stringent environmental and safety standards (such as RoHS and UL compliance), this component is heavily utilized across demanding sectors. It serves as a preferred choice for automotive electronics, including Advanced Driver Assistance Systems (ADAS) and New Energy Vehicle (NEV) battery management units, as well as high-density data center servers and complex industrial control mainboards where operational failure is simply not an option.
