D-Sub Connectors

The FCC17B25PC65B is a sub miniature D-Sub connector designed by Amphenol, a major manufacturer of electronic connectors found in many industries. It is a standard 9-pin connector consisting of two rows with five pins in the top row and four pins in the bottom row. Due to its size of only 17mm x 25mm, it is one of the smallest D-Sub connectors available, making it perfect for many applications where space is limited.

Application Field

The FCC17B25PC65B is used in many industries, including aviation, medical, industrial automation, military, automotive, communication and consumer products. It is a popular choice in medical applications as it allows equipment to be designed smaller and lighter, making it ideal for portable medical imaging equipment. In industrial automation it is often used in robotic and drive control systems. In military and aerospace industries it is used in harsh environments where environmental sealing is paramount.

Working Principle

The FCC17B25PC65B works by using pins to make electrical connections which are then held in place by a housing. The performance of the connection depends on the quality of the contact, the pin material, the plating material and the type of housing used. It is usually made from brass or stainless steel which have been plated with gold, tin or silver to improve corrosion resistance and make a better connection. The contact material can be either gold or copper and the outer shells can be aluminium or thermoplastic. The assembly is then sealed to protect it from dust and other foreign contaminants.

The FCC17B25PC65B is designed to handle high speed data communication, up to 10 Gbps and up to 280 VDC. It has excellent signal integrity due to its low insertion loss, return loss and crosstalk. Additionally, the connector has a very low electrical noise and excellent protection against EMI interference.
