Introduction

M85049/88-21N03 is a circular connector that is used in conjunction with backshells and cable clamps to assist in connecting and disconnecting wiring harnesses from electronic components. The connector is a male to female, 2-pin part made of aluminum and features a screw lock and an internal lip seal. It is designed for use in high intensity environments such as aerospace applications where extreme reliability and resistance to harsh environments are essential.

Application Field

The M85049/88-21N03 connector is most commonly used in aerospace applications where vibration, shock, and extreme temperatures are present. It is also suitable for manufacturing, automotive, and medical applications where reliable and secure connections are required. The connector can also be used in high temperature and high vacuum environments. It is also suitable for applications in rugged outdoor conditions.

Construction

The M85049/88-21N03 connector is constructed of aluminum. The body of the connector is designed with an internal lip seal which further protect against dust and moisture build-up. The contacts are made of brass and the screw lock is aluminum. The connector is further protected by a black zinc die cast cover.

Working Principle

The M85049/88-21N03 connector works by sliding the backshell onto the wiring harness. The screw lock is then tightened to secure the connection. Once the connector is secure, the internal lip seal provides additional protection against dust and moisture build-up. After the connector is in place, it provides a secure connection that is able to withstand vibration, shock, and extreme temperature fluctuations. It is also able to handle electrical loads up to 6 amps.

Conclusion

The M85049/88-21N03 connector is a circular connector that is designed for use in high intensity environments such as aerospace applications. It is constructed of aluminum and features a screw lock and internal lip seal. The connector is designed to provide a secure connection that is able to withstand vibration, shock, and extreme temperature fluctuations. It is also able to handle electrical loads up to 6 amps. The connector can be used in conjunction with backshells and cable clamps to provide reliable and secure connections in a variety of applications.
