Rectangular Connectors - Headers, Male Pins, 3-827745-4 Application Field and Working Principle

The 3-827745-4 is a rectangular connector with male pins, and is part of a range of connectors & interconnects from manufacturer Weidmuller. It is suitable for use in a large variety of applications, including industrial, medical, military, broadcasting, and power communication fields. It is available in polarized or non-polarized versions, as well as different sizes and various mounting styles.

The 3-827745-4 is an example of a header type of connector. It is a single-row arrangement of electrical pins, designed to be connected to printed circuit boards (PCBs) with plated through-holes. The socket end is the part that houses the male pins, while the header end is the part that is soldered onto the PCB.

Working principle

The 3-827745-4 works by coupling electrical connections between two devices. For example, it can be used to connect a PC motherboard to a PCI Express card, or an electrical harness to a panel mount. It operates on the same principle as other header type connectors, using metal pins that make contact when inserted into the mating connector socket. The pins are spring-loaded and held in place by friction or a locking mechanism. This ensures a reliable connection and proper alignment of the pins when the connector is engaged.

The 3-827745-4 header connector has an oil-resistant base insulation material and a zinc-plated steel housing. The pins are gold-plated for optimum electrical and corrosion resistance, and are spring-loaded for improved contact with the mating connector socket. The connector also features a dual locking system for secure mating when the connection is established.

Application field

The 3-827745-4 header connector is widely used in various applications such as automotive, industrial, medical, military, broadcast, and power communications. It is suitable for use in harsh environments, where the connector needs to be rugged and durable.
