MS27505 MIL-DTL-38999 Square Flange Receptacle Connector

Overview of the MS27505 Connector

The MS27505 connector is a high-performance circular receptacle designed according to the MIL-DTL-38999 standard, one of the most widely used military connector specifications in the world. Known for its rugged construction and reliable electrical performance, this connector is commonly used in industries where durability and stability are critical.

As a square flange receptacle, the MS27505 connector is designed for secure panel mounting. It provides a stable electrical interface between equipment and cable assemblies, ensuring reliable signal or power transmission even in harsh operating conditions.

Thanks to its compact structure and high reliability, the MS27505 connector is widely applied in aerospace systems, military equipment, industrial control systems, and transportation electronics.

Aluminum Alloy Shell for Strength and Durability

The MS27505 connector features a high-strength aluminum alloy shell, which provides excellent mechanical performance while keeping the overall weight relatively low. Aluminum alloy is widely used in circular military connectors due to its combination of strength, corrosion resistance, and lightweight characteristics.

The housing is typically treated with protective coatings that enhance resistance to oxidation and environmental exposure. This helps the connector maintain long-term performance in demanding environments such as high humidity, vibration, or temperature fluctuations.

Because of this durable construction, the connector can withstand frequent mating cycles and mechanical stress, making it suitable for applications that require long service life and consistent reliability.

Square Flange Panel Mount Design

One of the defining features of the MS27505 connector is its square flange receptacle design. The connector is installed through a panel using a four-hole flange mounting structure, which ensures stable positioning and strong mechanical support.

This mounting style provides several advantages:

1.Secure attachment to equipment panels

2.Improved resistance to vibration

33.Easy installation and maintenance

4.Reliable alignment with mating connectors

The square flange design also helps maintain proper contact alignment, which contributes to consistent electrical performance and reduces the risk of connection issues during operation.
