The mounting flange on each end secures the housing to a panel — useful when the connector sees cable strain or the harness is pre-assembled before final installation. ## What the 3.81 mm Pitch and 20 Positions Mean for Your Fit The 0.150\" (3.81 mm) pitch sets the board footprint for the mating header — a common spacing for medium-current power connectors, wider than signal-pitch headers so the PCB traces can carry 5-8 A per circuit without necking down. 20 positions in two rows means the header footprint is about 38 mm long by 9 mm wide (plus the mounting flanges), which fits a standard industrial PSU or motor-drive board. ## Wiring Note — Order the Terminals Separately This housing ships without contacts. The housing accepts the terminal after crimping; the push-pull fastening holds the terminal in the cavity without a secondary lock. For a production harness, order the housing and terminals together so the assembly line has both halves ready. The mounting flange is the only retention feature on the housing itself — the cable strain is managed by the terminal crimp and any external cable tie, not by the housing latch.","metaTitle":"TE Connectivity 178803-8 Dynamic D-3100 Plug Housing, 20 Pos","metaDescription":"TE Dynamic D-3100 178803-8 plug housing, 20 positions, 3.81mm pitch, 2-row, panel mount.
