Right-angle wire-to-board header for power distribution
The 178495-1 is a 2-position, single-row header from TE's Universal Power series, designed for board-to-cable/wire applications. The 0.156" (3.96 mm) pitch is a common spacing for power connectors, giving you room to route thicker wire gauges without crowding the PCB. Right-angle through-hole termination keeps the mating axis parallel to the board, useful when the enclosure height is tight or the cable exits along the board edge. The shrouded 4-wall design protects the tab contacts from damage during handling and guides the mating receptacle into alignment, reducing the chance of bent pins.
Locking ramp and board lock for secure assembly
This is a practical safeguard in equipment that sees vibration or cable tugging—the connection stays put without relying on the friction fit alone. Board locks on the mounting posts anchor the header to the PCB during wave soldering, preventing the part from floating or skewing. After soldering, they add mechanical retention against the shear force from the cable harness.
Temperature range and plating for industrial environments
The tin-on-tin contact finish (both mating and post sides) is cost-effective for moderate mating-cycle duty. Current rating is listed as varying by wire gauge, which is standard for a tab-type header: the actual ampacity depends on the crimp terminal and the wire size used in the mating half.
