Product Description
The CDB4/1Y is a high-quality industrial feed-through terminal block designed for safe, reliable, and efficient electrical wiring in control panels, automation systems, and power distribution applications.
It is engineered for secure electrical connectivity, low contact resistance, and long operational life, making it ideal for demanding industrial environments such as PLC control panels, machine automation systems, and electrical distribution boards.
The CDB series is widely used in modern panel building due to its compact modular design, vibration resistance, and strong insulation properties, ensuring stable performance in continuous industrial operation.
The “Y” variant typically represents a yellow color-coded identification type, commonly used for special circuits, safety lines, or signal identification in electrical panels.
Working Principle
The CDB4/1Y operates as a feed-through terminal block, allowing electrical current or signals to pass from one side of the terminal to the other through an internal conductive clamp system.
When a conductor is inserted and tightened, the internal metal clamp applies uniform pressure on the wire, ensuring a stable, low-resistance electrical connection.
This prevents loosening due to vibration, heat expansion, or mechanical stress, ensuring safe and continuous electrical performance in industrial systems.
