The 39870-0509 terminal block is an important component of Headers, Plugs and Sockets. It is designed for use in applications requiring electrical and mechanical connection, such as industrial and digital control systems. It has a modular design and is compatible with standard DIN rail types.

The 39870-0509 terminal block provides a positive, secure electrical connection when used with the appropriate accessories, such as screwdrives, flat head screws, and nuts. It is also available in a wide variety of sizes for applications requiring the same base pattern. The contacts have been silver plated for low electrical contact resistance.

The working principle of the terminal block is quite simple. When a contact is inserted into the socket, a spring-loaded contact pin slides into the contact and makes the electrical connection. If the contact is removed, the contact pin slides out, thus breaking the connection. This is called a “make before break” connection and ensures that no electrical current is lost during installation.

The 39870-0509 terminal block also offers a reliable ground connection. It is designed with a spring-loaded ground screw, which can be tightened or loosened by tightening or loosening the nuts on either side of the ground screw. This ensures that the ground connection always remains secure.

The terminal block also features an internal corrosion protection system. The contacts are sealed to the board to prevent moisture ingress and corrosion. This ensures long-term reliability and makes it suitable for industrial applications with harsh environmental conditions.

The 39870-0509 terminal block is also easy to install and use. It requires no wiring or soldering and can be installed quickly and easily with minimal training. The contacts are also interchangeable, so additional contacts can be added or removed as needed.

In conclusion, the 39870-0509 terminal block is an important component of Headers, Plugs and Sockets. It offers reliable electrical and mechanical connection with reliable ground connection and corrosion protection. It is easy to install and use, and is suitable for a wide variety of industrial applications.
