terminal blocks, also known as barrier blocks, are electronic component used to physically connect two or more electrical wires or cables together. The CDM-21, also commonly referred to as the barrier block, is a popular termination block solution commonly used to simplify wiring and reduce costs.The CDM-21 terminal block consists of two housing parts secured together by two metal screws. A terminal bridge is pre-inserted during production and is designed to carry current through the connection. The contacts can accept both signal level and power cables.The CDM-21 terminal blocks are constructed of the toughest materials available and have one of the highest temperature ratings of any barrier block available. Each CDM-21 contains two wings allowing multiple unit connection while keeping the integrity of the wiring. This allows for excellent scalability and cost-effectiveness for any application.The CDM-21’s working principle is simple but offers a variety of different features such as terminal to busbar connection, wiring continuity, and easy installation. These features enable the CDM-21 to act as a bridge between one or more cables and on the other side to the end device.The terminal blocks allow connection of multiple cables, providing a secure, safe and reliable environment for power to be transferred. In addition, the CDM-21 terminal blocks can easily accept two or more wires at once, providing flexibility for a wide range of applications. The barrel of the block itself is made to make electrical connections, or to allow for proper insulation of the wire.In conclusion, CDM-21 terminal blocks offer a reliable solution for connecting cables in a variety of applications. This terminal block is constructed from a special ABS thermoplastic, providing maximum durability and superior electrical insulation. It includes two wings that allow multiple units to be connected together while allowing for maximum scalability. The contact and operation system is designed to provide electrical continuity between the cables, making it easy to install and maintain. Finally, the barrel is made to accept all sizes of wire, allowing for maximum versatility.
