D-Sub Connectors

D-sub connectors or D-subminiature connectors are a type of electrical connector used for a variety of signals and are popular for general use due to their compact size. They are frequently used in computer applications for cable and port management. The specific connector model to be covered in this article is the FCC17B25PE4E0.

Application Field

The FCC17B25PE4E0 is a 15-pin D-sub connector with the following application fields:

• Industrial and Commercial Data Communications
• Computer and Peripheral Control
• POS/PCI/ISA/EIA-485/MSA

The device has mounting holes for PCB or panel assembly and is rated for a maximum operating temperature of 125°C and a contact resistance rating of 30 milliohms.

Working Principle

The inner workings of the FCC17B25PE4E0 are divided into two sections - the body and the contacts. The body consists of an insulated thermoplastic shell that houses the contacts, which are comprised of strips of metal bent into channels. The channels are arranged into sets of two - one for the signal line and one for the ground line - which creates a very stable and reliable interface between two electrical components.

When it comes to installation, the FCC17B25PE4E0 is a plug-and-socket type device that uses crimp-style termination. This means that the contact pins are crimped directly onto the conductor wires, eliminating the need for soldering. This feature makes it a very popular choice for industrial and commercial applications where reliability and versatility are essential.

The FCC17B25PE4E0 can be used to transfer data signals, power, or a combination of both. It is designed to handle up to 2.5A (maximum) current in each direction and is rated for 300V (maximum) voltage. It also has a rated insulation voltage of up to 1kV (rms) and a dielectric strength rating of 3kV (rms).

Conclusion

In summary, the FCC17B25PE4E0 is an incredibly solid and versatile 15-pin D-sub connector that offers many features for easy and reliable installation. With its crimp-style terminating and high current and voltage rating, it is well-suited to a variety of industrial and commercial applications.
