MS27508E12B4P 4-Pin Circular Connector for Aircraft Avionics Wiring

SF Series Aviation Connectors Specifications and Performance Data

MS27508E12B4P Circular Connector Overview

The MS27508E12B4P circular connector is a high-performance interconnect solution designed for aircraft avionics wiring systems and other demanding aerospace applications. Built to meet stringent military specifications, this connector provides reliable electrical connections in environments where durability, stability, and safety are critical.

Key Selection Criteria for Avionics Interconnects

When evaluating circular connectors for avionics platforms, consider the following decision points:

• Pin Configuration: The 4-pin layout supports compact wiring runs where space and weight are constrained.
• Mating Gender: Available in male or female configurations to match your existing harness or panel design.
• Environmental Resistance: The aluminum alloy housing is suited for vibration and temperature variations common in aviation electronics.
• Contact Integrity: Brass contacts with gold plating support stable signal and power transmission over extended service life.

Construction and Material Performance

The connector's housing is machined from aluminum alloy, providing a favorable strength-to-weight ratio for airborne installations. The contacts are manufactured from brass and plated with gold, a combination chosen to maintain low and stable contact resistance in demanding operating environments. This construction supports secure mating and reliable electrical performance for mission-critical applications.

Suitable and Unsuitable Applications

This connector is suitable for avionics modules, flight control systems, and onboard electronic equipment where dependable signal and power transmission is required. It is an appropriate choice for manufacturers and integrators seeking dependable circular connectors for mission-critical applications.

However, it is not intended for subsea or prolonged underwater submersion, nor for applications requiring high-density pin counts beyond the 4-pin configuration. For applications with different pin counts or environmental sealing requirements, please consult our Aviation Plug Connectors range or review the SF Series Aviation Connectors Specifications and Performance Data for alternative options.
