They make it simple to disconnect and reconnect wires to the board and are utilized in PCB designs where space is an issue. In contrast to larger terminal blocks (e.g., 5.08mm pitch), they can manage lower current and voltage levels. The terminal block connector's model or series number is 15EDGKN. The model number's "EDG" frequently denotes that it is a pluggable connector in the European style. The distance between the centers of one pin and the next pin is known as the pin pitch, and it is 3.81mm. A typical pitch for signal or low-power applications is 3.81 mm. Seven-pin: This indicates that there are four pins or places for wires to be connected on the connector. Included in the kit: 1
