MS3181-20NAL Application Field and Working Principle

The MS3181-20NAL from Amphenol Corporation is a Circular Connector accessory with a threaded coupling used to secure the connector to the mating surface. It is designed to work with the Amphenol MIL-C-5015 series circular connectors that have 20 contacts and four shells.The MS3181-20NAL connector is manufactured in accordance with military specifications and is composed of several components. It features a nickel plated brass body and a nitrile rubber gasket to prevent moisture and dust from entering the connector. It also includes a pair of locking latches, a locking nut, an elastomeric seal, and an anti-vibration clamp.The application field for this part is due to its compact size, durable construction, and installation ease. Its robust design makes the MS3181-20NAL suitable for use in harsh environments where shock, vibration, and extreme temperatures are present. The connector is commonly used in military, aerospace, automotive, communication, and transportation applications.The working principle of the MS3181-20NAL is relatively simple. It is designed to attach two mating circular connectors at a given distance. When the two parts are mated and the connector nut is twisted, the elastomeric seals and locking latches ensure the connection is firmly attached. The anti-vibration clamp helps to reduce any external forces that could potentially weaken the connection.Overall, the MS3181-20NAL provides a secure and reliable connection in a variety of applications. The connector is designed for field-dependent, harsh environments, and offers a durable and compact connection that is resistant to shock, vibration, and extreme temperatures. It is an effective solution for use in military, aerospace, automotive, communication, and transportation applications.
