Product Description
The CYDLGF4FT is a high-quality industrial feed-through terminal block designed for secure, stable, and efficient electrical connections in control panels, automation systems, and power distribution applications.
It is engineered to provide safe wiring, low contact resistance, high mechanical strength, and long operational life, making it suitable for demanding industrial environments such as machinery control systems, PLC panels, and electrical distribution boards.
The CYDLGF series is widely used in modern panel building due to its compact modular structure, vibration resistance, and flame-retardant housing design, ensuring reliable performance in continuous industrial operation.
The “FT” variant typically represents a front-tight / fast-tight connection design, optimized for easier wiring access and faster installation in control panels.
Working Principle
The CYDLGF4FT operates as a feed-through electrical connector, allowing current or signal to pass from one side of the terminal to the other through a secure internal conductive clamp system.
When a conductor is inserted and tightened, the internal clamping mechanism ensures uniform pressure on the wire, creating a stable, low-resistance electrical connection.
This prevents loosening due to vibration, thermal expansion, or mechanical stress, ensuring safe and continuous electrical transmission in industrial environments.
