M85049/31-20W Application Field and Working Principle

Circular connectors - Backshells and Cable Clamps are electrical components used to connect circuits to one another. The M85049/31-20W is a solder cup backshell designed for use in military, aerospace and general industrial applications. It offers a number of features, including EMI/RFI screening, strong strain relief, and improved environmental protection. M85049/31-20W backshells are available in split and solid versions and feature a highly durable sleeve and body that provide strong strain relief. They also include an adjustable gland nut that provides the necessary tension to ensure a reliable connection. The M85049/31-20W is designed to accept wire sizes ranging from 24 to 26 AWG in MIL-C-55302/RL, MIL-C-38999/RL, and other circular connectors. The M85049/31-20W provides the user with a high degree of EMI/RFI screening as well. This is achieved by the combination of a spring-loaded ring that wraps the connector and a shielded backshell. The spring-loaded ring ensures that the connector does not come loose even under vibration or shock, allowing for reliable EMI/RFI protection. In addition, the M85049/31-20W also provides improved environmental protection. Its body is constructed from non-cellular polyolefin, providing protection against ozone, solvents, UV rays and temperature extremes. The backshell is also designed to protect against vibration, EMPs, salt and water. The M85049/31-20W offers a reliable and durable solution for military, aerospace, and industrial applications. Its combination of EMI/RFI shielding, reasonable cost, and environmental protection make it a popular choice for applications requiring reliable circular connectors.
