  • Pin count & current: 2–4 pins; 10A / 20A according to load.

  • Thread system: PG or metric (M) to fit enclosure knockouts.

  • Material: flame-retardant PA66/PC; UV-resistant for outdoor.

  3. Connect wires by color (terminal block or screw clamp).

  4. Tighten body & cap (compression forms IP68 seal).
