36-position, 5.00 mm pitch, 4-row vertical header
TE Metrimate 207121-9 is a 36-position, 4-row vertical header on 5.00 mm pitch — a dense but serviceable grid for power and signal in a single connector. The 4-wall shrouding with latch lock and mounting flange keeps the mating half aligned and locked under vibration, which matters in industrial cabinets and automotive ECU bays where the harness gets tugged during service.
The gold-plated mating contacts (30.0 µin) support repeated mating cycles in corrosive environments; tin-plated solder tails (150.0 µin) wet well in wave-solder processes. The UL94 V-0 nylon housing with black/red insulator color aids visual polarity checking on the line.
