Rectangular connectors, also known as headers or pins, are used in dozens of applications. One of the most versatile is the 281699-4, which is designed for medium amperage and has male pins. Male pins are designed to plug into female sockets. Therefore, the socket can be mounted on the board and the header can be used to connect multiple wires that may run through the same board.

281699-4 connectors are typically used in several applications. For example, they are typically used in automation components, such as sensors, actuators, and programmable logic controllers. They are also commonly used in communications and networking equipment, such as switches, routers, and base stations. Furthermore, these connectors can be used for power supplies and electrical equipment, including medical equipment and motors. Moreover, they may be used in automotive applications, such as starting and navigation systems.

The working principle of the 281699-4 connector is based on contact technology. The pins help to prevent current leakage, ensure correct contact between two surfaces, and create a solid connection without soldering. In addition, they reduce EMI and RFI interference.

These connectors are available in a variety of sizes, and they can be customized to meet customer needs. They are composed of three main components: body, contacts, and insulation. The body supports the contacts in the form of pins or blades that are inserted into an appropriate hole. The contacts are made of a corrosion-resistant material, such as stainless steel. The insulation is usually composed of a plastic material, such as PBT, which prevents contact between different pins and provides protection from environmental conditions and mechanical damage. The thickness of the insulation is proportional to the size of the connector and the electrical load it can carry.

Moreover, the 281699-4 connector provides a secure, reliable, and cost-effective connection. It is resistant to shock, vibration and abrasion, and it has a low insertion force, which makes it suitable for automated assembly. It is also RoHS compliant and UL listed.

In conclusion, the 281699-4 is a versatile rectangular connector for medium amperage applications. It is composed of body, contacts, and insulation, and is capable of providing a secure and reliable connection. It is available in various sizes, and can also be customized to meet customer needs. Furthermore, it is resistant to shock, vibration and abrasion, and has a low insertion force. Finally, it is RoHS compliant and UL approved, making it the ideal connector for many commercial, automotive, and industrial applications.
