M85049/74-12-2 Application Field and Working Principle

M85049/74-12-2 circular connectors, also known as MIL-DTL-38999 connector series 3, are used in applications where there is a need for up to 85 ways of power and signal contacts. These connectors provide protection against shock and vibration, resistance to overheating, and are robust and reliable. In addition, they are suitable for use in harsh environments and have excellent electrical performance.

M85049/74-12-2 circular connectors are commonly used in military, aerospace, and medical applications. The connectors are designed to withstand extreme temperatures and vibration, and they are constructed with very fine-pitch contact arrays, which allow for high-density, secure connections. They are also used in instrumentation, datacom, and test equipment.

The working principle of M85049/74-12-2 circular connectors is to ensure secure connection with a rotating and mating nut which offers the user greater flexibility compared to traditional cabling methods. The use of a rotating nut and threaded contact allows them to remain tightly-locked even when subjected to shock, vibration and other environmental stresses such as corrosion. The threaded contact allows for a secure mating whereas the rotating nut can be easily removed or tightened to produce reliable contact between the two halves of the connector.

M85049/74-12-2 circular connectors are also equipped with built-in environmental sealing. This sealing utilizes multiple levels of cuff and contact inserts that provide a positive, chemical-resistant seal against dust, fluids, and other contaminants. The sealing is also designed to prevent unintentional disconnection and to ensure that the contacts remain sealed even when subjected to shock and vibration.

M85049/74-12-2 circular connectors offer superior reliability and durability due to their ability to withstand extreme temperatures, dirt, moisture, and other harsh conditions. Additionally, the connectors are designed to provide accurate and reliable electrical performance, making them an ideal choice for distributed, complex systems and equipment with high-density connectivity requirements.
