Product details

Board Fit and Routing: 3.81mm Pitch, 4-Row Header

The 3-178216-2: This 12-position, 4-row header from TE's Dynamic D-3400 series uses a 0.150" (3.81mm) mating pitch with a 0.200" (5.08mm) row spacing. The 4-wall shrouded housing protects the tab contacts during handling and prevents bent pins during blind mating.

Suitable for general-purpose and industrial applications inside an enclosure where flame rating is required. Voltage rating is 250V. The connector style supports board-to-board or cable connections — confirm the mating receptacle part number for your specific harness or board stack.
