Rectangular connectors—headers, male pins—are widely used in a host of electronic applications. In this article, the focus is on the 81020-560203-RB connector, in particular, its use in engineering/electronic contexts and its working principle.

The 81020-560203-RB is a vertical header technology connector, a family of plug and socket connectors frequently used in electronic assemblies. This particular model is a breakaway type connector for wire-to-wire connection. This connector features a three row layer connection, with 8 pins, 0.1 spacing used in building electronic blocks and automotive applications.

Applications of the 81020-560203-RB connector range from power distribution to signal transmission within automotive battery pack modules, as well as non-automotive applications such as stud mount, remote panel mounted, and board-to-board connector assemblies. Due to the fact that it is a breakaway connector, it is popularly used in voice and data systems, test equipment, robotic systems, and medical electronics.

Connectors are generally used either for power or for signal applications. Power connectors are used to connect power to an electronic system, typically up to several hundred amps and can be either AC or DC. Signal connectors are used to carry signals between different electronic systems, generally from mV to several hundred volts. The 81020-560203-RB Connector is ideal for low voltage power and signal applications, and as such can easily handle an operating voltage of up to 120V.

The 81020-560203-RB has a unique design featuring an insulation displacement contact (IDC). This IDC contact is made of a flexible contact material such as phosphor bronze or copper beryllium alloys, which conforms to the shape of the wire, and makes a secure electrical connection between the wire and the connector. This design provides reliable connection between the wire and the contact, and maintains the continuity of the signal even under vibration.

The contacts in the 81020-560203-RB connector are recessed in the housing, and are connected to a pair of metal clips. These clips are controlled by two springs, and as the connector is engaged they are pushed into the insulation displacing contact area. This shape of contact also enables the contact to be occasionally twisted to ensure a secure connection and prevents contact bounce and vibration failure.

Connectors are widely used in all types of electronic systems, and the 81020-560203-RB connector is no exception. From automotive applications to consumer electronic products, this unique type of connector provides reliable performance for a variety of applications. With its easy connection and insulation displacement contact design, the 81020-560203-RB connector is an ideal choice for reliable high power connections.
