IntroductionED655/6DS terminal blocks are a kind of Wire to Board connectors in the terminal block family. Their application field and working principle are dominating, which make them a suitable choice for many electrical connections. This article will discuss and explain the features, application fields and working principles of ED655/6DS terminal blocks. FeaturesED655/6DS terminal blocks are equipped with a range of features, making it a great option for electrical connections. It has a current capability of 8A and voltage capability of 250V. It has a pitch of 4.2mm and a tracking of 1.3mm. The area of contact is 0.3mm2 for standard models and 0.3mm2 for optional versions. The contact material is nickel-plated brass, to ensure electrical continuity after repeated connections. The insulation cover is made up of polyamide which has a flammability rating of UL 94 V-2. It has several colors and lengths to suit different applications.Application FieldThe application field for ED655/6DS terminal blocks is sizable due to its features and characteristics. Mainly, it is suitable for most electrical wiring in industrial environments, due to the fast and secure connections that it provides. Common applications include residential wiring, automotive wiring, computer peripherals, electronics circuitry, etc. In harsh environments the strong insulation cover helps to prevent moisture and dust from entering and causing electrical break downs. Working PrincipleThe working principle of ED655/6DS terminal blocks is relatively simple when compared to other wire to board connectors. It has two separate contacts for each wire, one contact for the solid core wire and the other one for the stranded core wire. They are connected both to the base of the terminal block and each other for a secure electrical connection. The gap between the contacts ensures electrical isolation for each wire. The thumbscrews of the terminal block help to secure the wires by tightening against the contact. This compresses the contact to ensure better electrical continuity and reduce resistance.ConclusionsOverall, ED655/6DS terminal blocks have numerous features which make them a great option for electrical connections in a wide range of applications. Its features and working principles are simple yet effective, providing fast and secure connections. Thus, ED655/6DS terminal blocks are one of the most popular choices in the Wire to Board connector family.
