3-647047-8

The 3-647047-8 is a rectangular connector header from the family of connectors. It is an 8-pin connector with a 0.053 inch pin spacing and a locking option. This type of connector is often used to connect two PCBs. It has a durable, reliable, and high-algorithm nature and is widely used in various industries and applications.

Features of 3-647047-8 Connector Headers

• Threaded or locking mechanism
• Panel mounting option
• Orthogonal Polarity pins on mating halves
• Staggered voltage and signal pins
• Rated current 2.5A per pin
• Rated operating temperature range: –25 °C ~ + 85 °C
• UL 94V-0 flammability rating
• Molded strain relief for improved EMI/RFI shielding

Applications of 3-647047-8 Connector Headers

The 3-647047-8 connector headers are primarily used in motor controls, power supplies, industrial control panels, automotive, telecommunication, security systems, medical equipment and other applications. Its UL 94V-0 flammability rating facilitates reliable operations in a wide range of environments. The threaded or locking mechanism ensures low contact resistance even after frequent connector mating cycles. The pins on the halves of the connector facilitate orthogonal polarizing. The staggered voltage and signal pins help to reduce coupling between adjacent signals and the molded strain relief reinforces the shield against EMI/RFI

Working Principle of 3-647047-8 Connector Headers

The 3-647047-8 connector header is designed to interconnect two pieces of PCBs, usually with ribbon cables. The connector housing has an assembly of two housings, the housing A and housing B. Housing A consists of 16 pins in total, 70% of which are the voltage pins and the rest are signal pins. It is secured by two screws, and the housing B is a shield featuring eight holes for the signal pins. Both housings are molded together by means of plastic injection molding.

In use, the connector is assembled by inserting the housing A into the panel for connection. Then the two halves are slid together and secured with the screws. The screw mechanism absorbs the shock of insertion and prevents wear and tear. The signal pins are soldered to the board in housing B, and the voltage pins soldered to the board in housing A. The orthogonal polarity pins on the two halves ensure accurate alignment of the two connectors.
