Description
80PCS PCB Screw 5.0MM KF128-2 KF128-3 Terminal Block Connector Kit
The 80PCS PCB Screw 5.0MM KF128-2 KF128-3 Terminal Block Connector Kit is a practical assortment of 5.0 mm pitch screw terminal blocks designed for connecting wires to printed circuit boards. The kit includes 2-pin and 3-pin KF128 series PCB terminal blocks, making it suitable for power inputs, control circuits, signal wiring, automation modules, DIY electronics and repair work.
KF128 terminal blocks are through-hole PCB connectors. They are soldered directly onto the circuit board, while the external wire is secured by a screw clamp. This provides a strong, serviceable and reusable connection without the need to solder the wire directly to the PCB.

🔌 Why Choose KF128 Terminal Blocks?
KF128 PCB screw terminal blocks are a popular and cost-effective solution for creating reliable wire connections on electronic boards. The 5.0 mm pitch provides convenient spacing for wire installation, while the screw clamp offers a firm and reusable connection. This makes them ideal for both prototype and finished electronic assemblies.
⚠️ Notes
- Do not exceed the rated voltage or current specified by the manufacturer.
- Make sure that PCB tracks, solder joints and wire sizes are suitable for the expected load.
- When used in mains-voltage circuits, proper insulation distances, electrical safety rules and certification requirements must be followed.
- In applications with vibration or thermal cycling, periodic screw-tightness inspection is recommended.
