The SEFCX-21 is a type of terminal barrier block used in various industrial and commercial applications, most commonly as a wire-to-wire connection. The block consists of two terminal posts connected in series by two copper or tin-plated copper strips. The strips are coated with an insulation material to prevent accidental short-circuits in the line. In addition, the posts are also protected by a plastic material to prevent accidental contact with the wiring.

The electromechanical connection between the two posts is strong enough to prevent any physical movement which could lead to wire pull-outs. The block offers a secure and dependable solution for high-voltage applications. It can also be used in low-voltage applications such as electronic circuits, instrumentation, and automotive electrical systems, providing a secure connection and preventing unintended interference.

The SEFCX-21 terminal block is available in several sizes and configurations to meet the needs of different applications. The terminals are designed to accept wire sizes from 25 gauge up to 16 gauge. It is also available with optional contact plates and mounting end ferrules for additional safety and support. With its robust design and reliable performance, the SEFCX-21 terminal block is ideal for applications which require superior performance and long-term stability.

The working principle of the SEFCX-21 terminal block is based on the principle of electrical conduction. This principle states that electricity will travel from one pole to another when a voltage is applied between the two poles. The voltage is transmitted through the copper or tin-plated copper strips, and is regulated by the insulation on the strips. The electricity then passes through the terminal posts and into the connected device.

When a voltage is applied, the terminal posts are heated up due to the resistance of the terminal strip wire, and the two terminals become electrically connected. This ensures a secure and reliable connection between the wire and the connected device. The terminals will only be connected when a certain voltage is applied, which makes it impossible for the connection to accidentally short-circuit.

The SEFCX-21 terminal block is a reliable and dependable solution for electrical connections. It is ideal for a wide range of applications which require secure and stable performance. With its robust design and reliable performance, the SEFCX-21 terminal block is the perfect choice for anyone looking for a reliable, dependable, and secure connection.
