2-1971774-4

Rectangular Connectors - Housings

The 2-1971774-4 rectangular connector is a high-quality D-sub miniature connector that is ideal for a wide range of applications, from industrial machinery and business machinery, to audio/video devices and consumer electronics. Its unique design makes it well suited for applications that have limited space or require high-density mounting.

The 2-1971774-4 is an all-plastic housing for electrical or optical connectors. It is made of polycarbonate, a highly durable and strong thermoplastic material that is able to withstand environment pressures and extreme temperatures. It is also resistant to ultraviolet radiation and flame retardant, and it is shock and vibration resistant. This ruggedness provides reliability and a long service life for the application.

The 2-1971774-4 is suitable for assembly to an accessory or component, or as a stand-alone connector. It has a wide range of mounting options including direct-to-board, snap-in, peg-mounting, or screw-in; depending on the application. The 2-1971774-4 also features a variety of contact and shell options for optimal electrical or optical contact configuration.

Application Field and Working Principle

The 2-1971774-4 is a great choice for many applications, including industrial control, medical, automotive, office equipment, and transportation. It is particularly well-suited for applications that require a low-profile connector or have limited space.

The 2-1971774-4 is designed for both electrical and optical signal transmission. For electrical, the connector contacts are formed with riveted crimp contacts along with insulating hardware. The contact wires are insulated with dielectric material, which helps to protect them from oxidation and enables them to carry signal intact and reliably. The contacts are further protected by a mechanical shell, providing additional shielding.

The optical version of the 2-1971774-4 is built differently than the electrical version. The optical contacts are optical fibers that transmit data over a larger distance with less signal attenuation. The optical contacts are housed in small ferrule sleeves that are held together by a tight-fitting crimp, which makes the connection reliable and resistant to vibration and environmental factors. The optical contacts are then protected by a mechanical shell, providing additional shielding.

Regardless of the application, the 2-1971774-4 connector ensures an excellent performance with great reliability and a long operating life. Its rugged construction and reliable contact design make it one of the most trusted connectors on the market today.
