Terminal blocks, also known as terminal strips, are a type of electrical connector which consists of many types, such as those with headers, plugs and sockets. This article is dedicated to discussing the application field and working principle of XW4K-04A1-V1, one of the most popular varieties in this category.XW4K-04A1-V1 is a type of plug & socket terminal block. It utilizes quick-connect terminals and PCB-mounted assemblies with a 4mm pitch in a variety of sizes. The size of its PCB mounting is 10.1 x 9.4 mm. It is widely applicable in industrial automation, automotive and control equipment in areas such as sensor, communication, power and signal. The main purpose of this connector is to be used for power, grounding, control, over-current, and over-voltage protection.The working principle of XW4K-04A1-V1 is quite simple. It utilizes quick-connect terminals to ensure a secure connection between the PCB and the external device, with reliable power and signal flow. The terminal contacts are made of phosphor bronze and are plated with tin for enhanced conductivity and maximum reliability. The terminal blocks feature screw-less assembly and quick-release mechanisms for easy and fast connection.The XW4K-04A1-V1 has an inbuilt surge protection circuit, which ensures that even if there is an unexpected surge or short circuit, it will still function properly. This means that the circuit will not get damaged, thus avoiding expensive repairs and replacing components. In addition, it is designed to endure corrosion, shock and vibration, as well as other extreme conditions.In terms of safety, XW4K-04A1-V1 has a set of advanced safety features as well. The terminals feature a positive locking mechanism that prevents unintentional release of connection during operation, ensuring that the connections remain intact and secure. Also, if a short circuit or surge happens, the safety mechanism will immediately disconnect power and signal flow to protect other parts from getting damaged.To sum up, XW4K-04A1-V1 is a versatile type of terminal block that is suitable for both industrial and automotive applications. With its secure connection and advanced safety features, it has become one of the most popular terminal blocks in its class. It is capable of enduring corrosion, shock and vibration, as well as other extreme conditions. Now, it has become indispensable to engineers and technicians in various industries.
