The LEMO F Series connectors are ruggedised connectors that are designed for harsh environments. Compared with traditional MIL connectors, the LEMO F Series connectors are smaller, lighter and easier to install, with the same performance.
The handbook introduces the LEMO F Series ruggedised connectors, developed for defence, aerospace and motorsport applications where space, weight and reliability are critical. It explains the push‑pull self‑latching system, keying options and sealing solutions that enable high‑density, vibration‑resistant installations.
Technical sections provide material selections, IP protection ratings, electrical contact ratings, current‑carrying capacities and a full list of accessories and tooling required for assembly and testing. The document also includes a maximum‑current table and safety notices for proper handling.

|---|---|
| Current rating (2‑way 9.0 mm plug) | 10 A continuous |
| Current rating (3‑way 9.0 mm plug) | 8 A continuous |
| IP rating (mated) | IPG7 |
| IP rating (unmated) | IP68 |
| Maximum current (0.50 mm² conductor, Group 2) | 9 A |
It provides IPG7 protection when mated.
They are designed for up to 500 mating cycles.
Up to 10 A continuous.
