Introduction of 7731-127-36LF

7731-127-36LF is a header which belongs to the rectangluar connectors category. It is an IDC interface connector with scoop-proof and polarization features. It is compatible with the related cables corresponding to ribbon specifications, and also provides an easy assembly for tapping and termination of those cables.

Specifications & Features

7731-127-36LF is designed as a shielded contrast-locking header for computer applications and telecom boards. It is a type-A, double row receptacle with 1.27 mm (0.050 inch) centerline spacing between contacts, and it has 36 contacts. The header offers a variety of features, like low-profile, high-speed and low-coupling, which optimize signal integrity.The external shell is made of thermoplastic UL 94V-0, and the metal parts are gold-plated for better resistance against corrosion, abrasion and solder pot. The maximum voltage and current rating for this product is 50VDC, 0.5A. It has an operating temperature range from -55 Celsius to +125 Celsius.

Application Field & Working Principle

7731-127-36LF is mainly used to provide interference protection in hostile environments. It is well suited for small-scale and low-power applications like digital cameras, audio equipment, monitors, portable devices and others. The device is designed to reduce and prevent coupling of unwanted EMI radiation in order to maintain signal integrity.When assembled, 7731-127-36LF creates a crimp or press-fit connection into a PCB that is connected to the individual shield pins. Internally, it has one or more metalized plastic shields that provide extra protection from EMI radiation. Outside, the shielded contrast-locking header provides an effective shielding seal that dramatically reduces the amount of unwanted ambient noise and radio frequency interference entering the board.

Conclusion

7731-127-36LF is a double row, shielded contrast-locking header with 1.27mm centerline spacing that provides extra protection from EMI radiation. It is ideally best suited for applications exposed to harsh environmental conditions. This device is designed to reduce and prevent coupling of unwanted EMI radiation, which in turn contributes greatly to maintain signal integrity.
