It uses a single row of female blade socket cavities on a 10.40mm pitch — wide enough for the creepage and clearance needed in 48V and higher-voltage traction systems. The housing is molded in orange glass-filled PA66 (Nylon 6/6) and carries an IP6K9K ingress rating, meaning it withstands high-pressure, high-temperature washdown without water ingress.
What the IP6K9K Rating Means for the Harness
The IP6K9K rating means the housing seals against dust ingress and high-pressure, high-temperature water jets. The -40°C to 140°C operating range covers both cold-soak and exhaust-adjacent heat.
This is a housing-only part — contacts are not included. The female blade socket terminals that fit these cavities must be ordered separately from TE's HVA 280 terminal range, and they are crimp-terminated to the wire before insertion. If you are populating a harness, budget for both the housing and the matching crimp terminals plus the hand or auto-crimp tooling.
The closest functional peer in the evidence set is the TE 1-1703532-1, also a 2-position free-hanging housing with a 9.50mm pitch and a locking ramp fastening type. The 2103245-1 uses a 10.40mm pitch (0.9mm wider per cavity), an orange PA66 housing versus black PBT, and carries the IP6K9K rating versus a general 'Sealed' feature. The wider pitch gives more creepage for higher-voltage applications, and the PA66 material handles the 140°C upper temperature limit — the PBT in the 1-1703532-1 typically tops out around 125°C. If your application requires the full 140°C rating or the specific IP6K9K washdown standard, the 2103245-1 is the correct choice; for lower-temperature sealed harness work, the 1-1703532-1 is a cost-effective alternative.
