FTE-109-02-G-DH

FTE-109-02-G-DH is one of the most commonly used rectangular connectors in the market. Its application field is mostly for bridging connections between water, gas, air, and electricity. It is usually used to provide reliable connection for automotive, civil engineering and electronics applications where fitting quality and strength are needed.

FTE-109-02-G-DH is composed of two main components: the header and the male pin. The header is a plastic molding which contains multiple sockets in a line. This plastic molding is designed with either insulation or low-profile contact design, allowing for easy installation in tight space-limited applications. The male pin, as the name implies, is a cylindrical metal pin with a flat top that fits into the header perfectly.

FTE-109-02-G-DH\'s working principle is quite simple. When connected, the flat top of the male pin is inserted into the corresponding socket of the header. Then the header is tightened to offer a strong connection. The male pin is somewhat stuck inside the header due its design feature, therefore providing a secure fit. This is because its two contact points -- the metal pin and the socket -- form a reliable interlocking connection, thus preventing male pin flexing.

In summary, FTE-109-02-G-DH is one of the most efficient and widely used rectangular connectors in the market today. Due to its easy installation and strong interlocking connection, it is suitable for a variety of automotive, civil engineering and electronics applications. Its working principle is also quite simple and effective, making it rely on two contact points to form a secure connection.
