Rectangular Connectors, also known as Headers, Male Pins, are a form of connector used most commonly to connect PCBs, or Printed Circuit Boards, with other electronics. The connector type is often written out in ‘Gender Form’ with the first letter signifying whether the connector is Male (pin) or Female (receptacle) and the last letter signifying the connector type with “P” for Pin and “R” for Receptacle. The specific model number, in this case 850-80-018-40-251101, describes the type and size of the connector.

Broadly, rectangular connectors are divided into two major categories, board-to-board (often abbreviated as B2B) and cable-to-board (C2B). Board-to-board connectors are designed to be soldered onto two PCBs (or in some cases, just one), and are used to connect the two together. Cable-to-board connectors are designed to be mounted onto a PCB and then connected to a cable to receive signals from or send signals to other electronics.

The particular 850-80-018-40-251101 rectangular connector belongs to the cable-to-board category. It contains an 8-position pin header, where each position contains a 40 Amp, 8 AWG female receptacle. The total size of the connector is 1.26” x 0.2” with a pin spacing of 1/10” and a pitch of 0.03”. It is designed for heavy duty tasks such as manufacturing and industrial automation.

The working principle of rectangular connectors is quite simple. When connecting two boards, the male pins on one board are inserted into the female receptacles on the other board. This creates a snug fit between the two boards, which then transfers electrical signals from one to the other. Similarly, when connecting a board with a cable, the male pins on the board are inserted into the female receptacles on the cable, securing the connection.

In summary, the 850-80-018-40-251101 rectangular connector belongs to the cable-to-board category and is designed to be soldered onto a PCB. This particular connector contains 8-position pin headers with a pin spacing of 1/10” and a pitch of 0.03”. When connected, the male pins of the board (or one of the boards) is inserted into the female receptacles of the other component, thus forming a secure electrical connection.
