The Nextronics 302 Series screw‑type connector is designed for flexible PCB mounting with a 3.5 mm (0.138 in) center‑to‑center spacing and a recommended 1.20 mm (0.047 in) PCB hole. Standard configurations are 2‑ and 3‑way blocks, but any number of contacts can be combined by plugging them together.
The connector features a nylon housing (UL 94 V‑0) with optional brass, tin‑plated metal housing, stainless‑steel wire guard, and zinc‑plated M2 screws. Electrical ratings include 7 A current, 15 mΩ max contact resistance, 5000 MΩ insulation resistance at 500 VAC, and a 1500 VAC withstanding voltage. Mechanical specs list a 6.0 kg drawing force, 3.5 kg·cm max torque, and an operating temperature range of –55 °C to +105 °C.
