Rectangular connectors, headers, and male pins are essential components of any electrical or electronic system. The 350220-2 is a digi-key manufactured rectangular connector that has universal appeal for its ruggedness and affordability. This article will explain the 350220-2 applications field, as well as its working principle.

Overview

The 350220-2 connector is a type of 0.2 inch spaced board-to-board rectangular connector that fits onto printed circuit boards on either side. It is right-angle, so that two mated boards can be side by side in same orientation. It is a 2 row, 22 position connector with a plug and jack configuration. Each of the connector’s contact are gold plated to provide good electrical contact. The plastic polyester housing is UL approved. The contact is rated for 1amp, and is also rated at up to 250 volts.

Application Field

This type of rectangular connector is most often used in consumer electronics such as phones, televisions, and game consoles. The 350220-2 is also used in industrial equipment such as remote data acquisition (DAQ) systems and test equipment. This connector also finds applications in automotive systems, such relays, cold start systems, wipers, and air conditioners among others.

Working Principle

The goal of the 350220-2 is to join the printed circuit board on one side of the connection with the printed circuit board on the opposing side. The 350220-2 is designed to join two 3.3mm/ 0.13 inchsquare printed circuit boards. To begin assembling a 350220-2 connector, the contact pins must be inserted to the plug, one by one, and then the connector must be mated properly. The wire side is connected to its even spaced mating area on the plug.

The 350220-2 connector contains a total of 44 contact points. The plug has 22 contact points, and the jack has 22 contact points to which the plug contacts will connect. When the connector is forced into the mating area, the opposing contact points will mate, and then the currents will flow from one circuit board to the other. This ensures a reliable and local interconnection.

Conclusion

The 350220-2 connector is a universal board-to-board connector, that can be used in a variety of applications, from consumer electronics to industrial and automotive electronics. The contacts are gold plated, and rated for 250 volts and 1 amp. The connector consists of two 0.2 inch spaced mated boards on either side, both with 22 contact points each. The contact pins must be inserted one by one into the plug. Once mated, the contact points of the plug and jack make a secure, reliable connection.
