Terminal Blocks - Headers, Plugs and Sockets

Terminal blocks are widely used in numerous industrial and residential applications. OSTH404705B is a terminal block with header and socket connections. This type of terminal block uses spring clip connection method and its features, applications and working principle are discussed below.

Features of OSTH404705B terminal block

OSTH404705B is a 22mm wide terminal block comprising of a header, socket, accommodating screw and spring clip connection. It has a 10 pole terminal block with gold plated contacts. It is capable of sustaining a current of 17 A. @ 250V AC/DC. The header of the terminal block has a straight profile and 5.7mm disconnection depth. Screw connection is possible for both header and socket and uses the common M3 screws. It meet the requirements of UL with RoHS directive.

Applications of OSTH404705B terminal block

This terminal block is mainly used in lighting, industrial automation systems, measurement and control systems, frequency converter and motor control. Its features such as the compact design, spring clip connection method and 10 pole terminal block make it suitable for use in small and medium automation systems. It is also used in industrial circuits where 10A at 250V AC/DC connections are required.

Working principle of OSTH404705B terminal block

The OSTH404705B terminal block uses a spring clip connection method. This type of connection system involves a spring clip located inside the terminal block. When the connector is inserted into the socket, it causes a pressure on the clip which results in the electrical connection between the conductor and the terminal block. The spring clip also provides additional stability to the connection, ensuring its integrity for longterm usage.

The OSTH404705B terminal block has screw connection both at the socket and header side. The screws are tightened to ensure secure connection between the terminal block and the conductor. The gold plated contacts between the terminal block and the conductor ensure efficient and low resistance electrical connection.

This type of terminal block is also designed to meet the strict requirements of European regulations such as UL and RoHS directive. The UL certification ensures that the terminal block is compatible with international standards and benchmarks. The RoHS directive ensures that the terminal block is free of hazardous materials and is safe to use in a wide range of industrial and domestic applications.

Conclusion

The OSTH404705B terminal block is a highly robust terminal block with spring clip connection, suitable for a wide range of applications. Its features such as 10 pole terminal blocks, gold plated contacts, screw connection and certification from UL and RoHS directive make it an ideal choice for industrial circuits and residential applications.
