We are excited to present the UP-TPSEK3 J version, an advanced upgrade to the third generation UP-TPSEK. Designed for lower insertion forces, improved mechanical performance, and full compatibility with existing tools and connectors, this new terminal sets a new standard in efficiency and durability.

Key Features & Enhancements:

  • Optimized Contact Design – Ensures a lower force requirement for insertion, staying below 20N and closer to 15N, while maintaining consistent performance. This is 66% less compared to

    standard female terminals and 30% Less compared to UP TP SEK3 female terminals.

  • Improved Terminal Box Mechanics – A redesigned reaction force mechanism reduces peak insertion force and ensures a smooth, progressive engagement.
  • Validated Across Multiple Materials – Successfully tested on steel (4939J24) and brass (4939J) in natural, pre-tinned, and post-tinned finishes.
  • Enhanced Robustness During Crimping – New design is immune to small deformations occurring during the crimping process, ensuring reliability.
  • Full Compatibility – Works seamlessly with all TPSEK3 references (4935J, 4937J, 4941J, 4943J), existing stamping tools, crimping applicators, and with the existing Rast 5 RS5xxx connector family from 2 to 6 positions.
