The FCC17B25PM490 is a D-Sub Connector recommended for applications such as boards interconnecting, digital signal and data, and communications equipment. It features a 25-pin configuration and is 0.198" thick. It comes with polarized shell and contacts, plastic and metal components, and an extended temperate range of -40°C to +125°C.

The D-Sub connectors are available in various sizes and contact arrangements to meet different application requirements. The FCC17B25PM490 is a type of D-Sub connector that is specifically suited for applications involving board-to-board interconnects such as for digital-signal and-data communications. It is also the preferred connector for applications that operate between the temperatures of -40°C to +125°C.

The FCC17B25PM490 is constructed with polarized shells and contacts. The contacts are composed of phosphor bronze with gold-plating. This type of contact arrangement ensures both reliable signal transmission and long-term performance. The plastic and metal components, such as the insulators, contacts, and housings are designed to meet protection classifications of IP67, to guard against dust, solids, and water-resistance. The connector is also shielded with a zinc-plated shell to minimize RF interference.

The FCC17B25PM490 design features two main parts, namely the housing, and the contact assembly. The housing is secured in place with 4 hold-down screws and the contact assembly is collapsible. This part consists of a PCB with 25 surface-mounted contact pins. When the connector is engaged to another mating part, the contact pins make contact with the corresponding contacts in the other part. This signals are transmitted through the contacts, which are coated with gold plating, to allow a low resistance and hence a high signal quality.

The FCC17B25PM490 working principle is relatively simple. Two mating parts are attached to each end of the connector. When the two parts are engaged, the contacts of the FCC17B25PM490 make contact with the opposing contacts of the mating part. This creates a connection between the two parts that allows for a transmission of digital signals, data, and power. The contacts on the FCC17B25PM490 are gold-plated for low resistance and high performance. The entire assembly is then shielded with a zinc-plated shell that minimizes RF interference.

In conclusion, the FCC17B25PM490 is a type of D-Sub Connector suitable for digital signal, data, and communications equipment; in particular board-to-board interconnects. It features a 25-pin configuration with polarized shells and contacts. The contacts are constructed with phosphor bronze and gold-plating, for reliable transmission of signals and data. It is also designed to meet protection classifications of IP67 and comes with a zinc-plated shell for minimized RF interference. Its working principle is simple: when the two mating parts are engaged, the contacts of the FCC17B25PM490 make contact with the corresponding contacts in the other part, enabling signals and data to be transmitted.
