81040-600C04

Rectangular Connectors - Headers, Male Pins

The 81040-600C04 is a rectangular connector with headers and male pins. It belongs to a series of rectangular connectors developed by 3M, which are widely used in various applications for signal, power, and data transmission. Generally, a rectangular connector is made of two connector halves, one containing the female receptacle and the other containing the male pins. The 81040-600C04 is renowned for providing high-reliability and stability in arduous conditions.

Application Field of 81040-600C04

The 81040-600C04 has a wide range of applications. It is mostly used in harsh environments to meet the demands for signal, power, and data transmission. Typical applications are in military/space operations, aerospace/ aviation markets, data and communication networks, high-end synthetic data systems, medical systems, industrial systems, robotics, and instrumentation.

Moreover, the 81040-600C04 is suitable for high voltage, high current, medium speed DC, low speed DC and signal transmission. It is used in transmitting high-speed signals, power transients, etc. and to meet the requirements for higher transmission speed in harsh environment.

Working Principle of 81040-600C04

The working principle of the 81040-600C04 primarily involves the electrical connector. It is composed of two halves with a female receptacle and male pins, which are machined into two separate pieces, and then joined together by a soldered or crimp connection.

The male pins are made of non-magnetic metal, such as brass, aluminum or stainless steel, which have been plated with nickel. The contact area of the male pins has a high contact pressure, which ensures reliable electrical connections. And the fact that the pins are thick enough makes them suitable for several installations with different types of mating group.

In the female receptacle, a plated contact area is provided to ensure good electrical and insulation contact between the male pins and the receptacle. The contact area is designed to deflect the current pulse from pin to pin upon contact, allowing for more stable contact and increased reliability. Moreover, the female receptacle has an electrically conductive, thermally-conductive, flame-retardant or hard polycarbonate insulation layer which provides better protection against electrical, thermal and environmental stress while providing a reliable connection.

The 81040-600C04 has an IP67 protection rating which meets the requirements for protection against dust, water, sand, oil, sealants, and more. It also has a high level of protection against shocks, vibrations, and extreme temperatures. Furthermore, the 81040-600C04 is equipped with a qualified and compliant termination per MIL-DTL-38999 to ensure secure and reliable transmission with long service life.
