Product Description

A screw terminal block allows for the repeated connection of wires and strands to a circuit board without having to solder the cable itself. Each contact has a screw that securely clamps the stripped wire in place.

The 2.54 mm pitch corresponds to the standard spacing of perforated panels and breadboards, allowing the blocks to be soldered in or plugged in directly. No adjustment of the holes is necessary. For larger connections, multiple blocks can be connected in series without the need for additional wiring.

These terminal blocks are used wherever cables need to be frequently disconnected and reconnected—for example, with motors, sensors, or power supply lines in homemade circuits. Since there is no fixed signal assignment, each contact can be freely used for any signals, power lines, or data lines.

The connection pins are soldered into the circuit board using a soldering iron. The green plastic housing securely holds the metal contacts and ensures sufficient spacing between the terminals.

Safety Notice

This product is intended exclusively for building prototypes and for testing and development purposes and is not suitable for use in household electrical circuits. When soldering the connection pins, standard soldering safety rules must be followed. If you have any questions, consult a qualified electrician before use.
