The 3-176976-6: The header is physically a 3-position body, but only 2 positions are loaded with contacts. That third cavity is empty — if your BOM calls for 3 circuits, this part delivers only 2. The locking ramp (fastening type) holds the mating receptacle in place under vibration — a common requirement in industrial control cabinets and power supplies.
Through-hole termination, shrouded 4-wall, tin plating
Kinked pin, solder termination — the kink provides retention during wave solder before the solder joint solidifies. Shrouded on all four walls protects the pins from accidental shorting and guides the mating receptacle into alignment. Tin-on-tin contact finish is cost-effective for moderate mating cycles in indoor, non-corrosive environments.
Active production, ROHS3, UL94 V-0
Operating temperature range -30°C to 105°C covers most indoor industrial and commercial applications.
