281699-2 Application Field and Working PrincipleThe 281699-2 series of rectangular connectors is commonly referred to as a Headers, Male Pins, or simply a Host Connector. This type of connector is most commonly employed in electronic applications such as computers, electronic monitoring systems, communications equipment, electric power transmission, and telecommunications. It is a type of “no-tool” connection. The 281699-2 header is a type of electrical connector that has two or three pins which connect with one or more hosts. With two pins, the connector is typically used in signal applications such as attaching a display or sensor. With three pins, the connector will be used as part of a terminal block or to power an LED light. The pins of the 281699-2 are generally made of brass or copper and are designed to be self-aligning when mated. The pin is then mechanically locked in place with a stamped steel clip or a nylon fastener. The pins are also precision machined with a positive tolerant cylindrical design to help ensure a reliable electrical connection. The 281699-2 connector utilizes a quick disconnect method to ensure fast connection and removal in both tested and untested environments. The contacts are also plated with a nickel-plated finish to resist corrosion and oxidation. The 281699-2 connector has a different range of sizes, ranging from 1mm to 10mm. The contact width of each pin varies based upon the application. It is also designed to mate with a variety of other connectors such as rectangular, D-subminiature, or RJ-45 connectors. The applications for these connectors are widespread and can be used for a variety of purposes, such as connecting a high-voltage power source to a circuit board or connecting a laptop to a monitor. Overall, the 281699-2 connector is an extremely versatile and durable type of connector widely used in the electronics industry. Its unique design makes it ideal for a variety of applications and it can withstand harsh environmental conditions. Its small size and ease of connection/disconnection makes it a preferred choice in many design applications.
