MS27473 10-Pin MIL-DTL-38999 Series II Circular Connector

MS27473 Military Connector

Product Overview

The MS27473 10-Pin Circular Connector is a high-reliability electrical connector designed for demanding aerospace, military, and industrial applications. Built in accordance with the MIL-DTL-38999 Series II specification, this connector provides stable electrical performance and excellent durability in harsh operating environments.

With its compact circular design and high-density contact configuration, the MS27473 connector ensures efficient signal and power transmission. It is widely used in mission-critical systems where reliability, environmental protection, and mechanical strength are essential.

MIL-DTL-38999 Series II Standard

The MS27473 connector is part of the MIL-DTL-38999 Series II family, a well-known military connector standard developed for high-performance electronic systems. Connectors manufactured under this specification are engineered to withstand strong vibration, extreme temperature variations, mechanical stress, and harsh environmental conditions.

The Series II design features a bayonet locking mechanism, which ensures a secure connection and prevents accidental disconnection during operation. This makes the MS27473 connector ideal for equipment that requires stable electrical connections in demanding environments.

Durable Construction

One of the key advantages of the MS27473 circular connector is its rugged construction. The connector is built with an aluminum alloy shell that provides strong protection against corrosion, vibration, and mechanical shock.

In addition, the connector design helps protect internal contacts from dust, moisture, and other environmental contaminants. This ensures long-term reliability and reduces maintenance requirements for critical equipment. Because of its durable design, the MS27473 connector is widely used in systems that must operate continuously under challenging conditions.

Reliable Electrical Performance

The 10-pin configuration allows the connector to support multiple electrical connections within a compact interface. Precision-machined contacts, brass plated with gold, ensure consistent conductivity and help minimize signal loss.

Stable electrical performance is essential for modern electronic systems, particularly those used in aerospace avionics, military communications, and control systems. The circular connector design also allows for reliable mating cycles, ensuring dependable performance even after repeated connections and disconnections. These characteristics make the MS27473 connector a trusted solution for engineers designing high-reliability systems.

Typical Applications

Due to its compliance with military standards and robust design, the MS27473 circular connector is used in a wide range of demanding industries. Common applications include:

• Aerospace avionics systems
• Military communication equipment
• Radar and navigation systems
• Defense electronic devices
• Industrial automation and control systems

In these applications, reliable electrical connectivity is critical to ensure system stability and operational safety.

Selection Considerations

When selecting the MS27473 10-pin connector for your system, verify the shell size, contact arrangement, and keying orientation against your mating requirements. Confirm whether you need a plug or receptacle, and whether the application calls for a cable-mounted or panel-mounted configuration. The bayonet locking mechanism provides secure mating, but ensure the mating connector follows the same MIL-DTL-38999 Series II interface to guarantee proper fit and electrical continuity.
