Circular Connectors - Accessories

The MS3181-22CA is a type of circular connector, produced by a company called Mazzer Electronic. As its name suggests, it is designed for application in the fields of military and aviation, but is also used for many other applications. This article will discuss the application fields and working principle of the MS3181-22CA.

Application of MS3181-22CA

MS3181-22CA is mainly used in the fields of military and aviation, such as aerospace, missiles, tank and armoured ground vehicles and shipboard communications. It can also be applied in factory automation, robotics, test and measurement equipment, laboratory instruments, and medical equipment. The environment in which the circular connector needs to operate is between -55°C to +125°C and the voltage rating is 600V at 500mA.

Features

The MS3181-22CA comes equipped with a wide variety of features, such as a screened shell to prevent EMI/RFI, a stainless steel shell for protection from hostile environments and an epoxy seal to protect against moisture and dust ingress. It also has two keyed options for blind mating capability, two location tabs for easy insertion and removal, and two locking tabs for secure mating. The connector is also compliant with mil-spec requirements and UL/CSA certified.

Working Principle

The working principle of the MS3181-22CA can be broken down into two parts. First, the cable is inserted into the connector through the large cable insertion hole. The cable must be inserted as deeply as possible to ensure a secure connection. Next, the locking ring, which is located on the inside of the connector, is then twisted in order to lock the cable into place. This ensures a secure connection and also ensures the strain relief of the cable to the connector. Finally, the solder terminals located on the inside of the connector are then soldered into place to complete the connection.

Conclusion

The MS3181-22CA is a type of circular connector which is primarily used in the fields of military and aviation and can also be applied in factory automation, robotics, test and measurement equipment, laboratory instruments, and medical equipment. It comes with a wide range of features including a screened shell to prevent EMI/RFI, a stainless steel shell for protection from hostile environments and an epoxy seal to protect against moisture and dust ingress. The working principle of the connector is based on the insertion of the cable into the connector and then locking in place with the locking ring and finally soldering the terminal for a secure connection.
