The seal keeps water and dust out of the cavity when mated with the AMPSEAL 16 header — think underhood engine harnesses, exposed industrial sensors, or outdoor lighting junctions where a puddle splash is routine. The TPA is a secondary retainer that slides over the back of the terminals after they are crimped and inserted; it locks each contact in place so a pulled wire does not back the terminal out of the cavity. On a 2-position connector the TPA is fast to engage, and it eliminates the guesswork of whether every terminal seated fully. ## Mating and Termination — What It Connects To and How The free-hanging (in-line) mount means the connector floats in the harness, not bolted to a panel, so it follows the wire routing without stress on the terminals.","metaTitle":"TE AMPSEAL 16 2040278-2, 2-Pos Plug Housing, 4.50mm","metaDescription":"TE AMPSEAL 16 2040278-2 2-position plug housing, 4.50mm pitch, sealed with TPA.
