The GEC28SBSN-M89 is part of a line of rectangular connectors produced by the company Cannon. This set of connectors is necessary for assembling complex electrical circuits, making them ideal for a broad range of applications that involves designing and installing complicated electronic systems. It is typically used as a board-to-board, board-to-cable, or cable-to-cable connector.The GEC28SBSN-M89 features a gold-plated contact, which guarantees a high-performance connection even in harsh environmental conditions, and also has a robust overmold that provides additional protection against extreme temperatures and mechanical stress. This makes it suitable for applications in extreme environments such as radio and communication systems, and medical equipment, in addition to the military and aerospace sectors.The individual components used in the GEC28SBSN-M89 are designed in a particular way to ensure a reliable and secure connection between two or more circuits. It consists of a pin header with 5.08 mm pitch, a male pin terminal for the connection of wire, and a socket terminal for connecting the board and the pin header. The pin header has a robust rectangular construction, with four rows of pins spaced apart with passivation to prevent contact from oxidizing.The male pin terminal is made of 201 Bronze and contacts with the board via an stepped seal surface that prevents the terminal from moving during operation. The socket terminal is also made of 201 Bronze alloy and has two contact points which allow for a firm connection with the pin header.The working principle of the GEC28SBSN-M89 involves a mechanism where the pins of the pin header are inserted into the two contact points of the socket terminal and the contacts of the male pin terminal are inserted into the 3.00 mm contact surface. This is done by locking the male pins and socket into the frame in order to maintain the separation between the two connectors. The contact surface is then soldered in place and the connection is complete.In conclusion, the GEC28SBSN-M89 is a reliable and robust solution for connecting complex electronic circuits. It offers secure connections and excellent protection against harsh environmental conditions, making it an ideal choice for a variety of applications, such as the radio and communication systems, medical equipment, military and aerospace sectors.
