Q1: Can I use the Sumitomo 6187-2171 for engine-mounted sensors?

A: This housing is highly versatile and compatible with industry-standard 1.2mm terminal systems, specifically the TE Connectivity MCON 1.2 LL (e.g., C-1452674) and the Kostal MLK 1.2-Sm series.

Q2: Does this connector require a separate wire seal (SWS)?

A: Yes, the 805-120-521 is a sealed application housing. You must use Single Wire Seals (SWS) with an appropriate diameter (typically for a 3.55mm cavity) to maintain the waterproof integrity of the connection.

Q3: What is the purpose of the TPA latch on this model?

A: The Terminal Position Assurance (TPA) is a secondary lock that ensures all female terminals are fully and correctly seated within the housing. It prevents terminal back-out under high-vibration automotive conditions.
