Terminal Blocks - Barrier Blocks

The YK4121903000G Barrier Block is a type of terminal block which serves to electrically connect two points and provide connection between two electrical components, found in industrial control systems worldwide. The YK4121903000G is a multi-position barrier block that has up to five wires per terminal and up to 5 positions. This barrier block requires a flat blade screwdriver for assembly and is made of durable PVC material.

The application field of the YK4121903000G are mainly in industrial control systems, such as control panels and wiring harnesses. The terminal blocks are required in such systems due to their improved safety features, such as electrical separation and touch protection, which ensure the reliability of the system. Additionally, the YK4121903000G Barrier Block has proven to be very successful in harsh and dusty environments.

The working principle of the YK4121903000G Barrier Block involves the use of a flat blade screwdriver for assembly. The assembly consists of two parts, an upper part and a lower part. The upper part is composed of a stainless steel or copper contact with spring-loaded conductive blades. This contact is insulated from the cable or wire going through the terminal block. The lower part is made up of two insulating sheets, with slots for the wires to pass through. Between the two sheets is a copper conductor with a spring-loaded terminal.

When the upper part is inserted into the lower part, the screwdriver is used to ensure a tight connection between the two parts. The spring-loaded terminal creates a connection between the conductive blades and the copper conductor, ensuring a reliable and efficient electrical connection. When electricity passes through the terminal block, the conductive blades form a barrier between the electricity and the insulating sheets, ensuring the safety of the equipment being connected. The insulation sheets also protect against electric shock.

The YK4121903000G Barrier Block has proved to be a reliable and safe device for connecting two electrical components, especially in industrial control systems. Its easy to assemble design ensures a secure connection and the insulation sheets regulate the temperature during the operation, making it an ideal terminal block for a range of applications. Its multi-position design enables it to be used with multiple wires, making it one of the most versatile terminal blocks available.
