The modern aerospace industry requires mission-critical electrical and electronic systems to ensure safe operation. These systems include navigation and communication, engine, and flight control systems. Navigation systems help pilots find their way from one destination to another, while communication systems allow them to stay in contact with air traffic controllers and other aircraft. Engine control systems monitor and regulate engine performance, and flight-control systems keep the aircraft stable and on course.
The electricity for these systems is supplied through a network of cables and connectors. Aircraft electrical connectors are specially designed to withstand the harsh conditions found in an aircraft engine. They can withstand high temperatures, vibration, and fuel contamination. They also provide a secure connection that will
not fail under duress.
There are many different aircraft electrical connectors, each designed for a specific purpose. For military applications, connectors must meet certain Mil-Spec (Military Specification) requirements. Learn about the different types of aerospace and aircraft electrical connectors.
Aircraft Electrical Connector Types
In mission-critical applications like military and commercial aircraft, electrical connectors must be fully traceable, provide reliable performance, and meet space-
and weight-saving requirements. Here are the most common types of electrical connectors for aircraft:
- MIL-DTL-83733: This specification covers fluid- and environment-resistant, rectangular, miniature, and rack to panel electrical connectors. The connectors use rear release and removable crimp contacts, and they can handle continuous operation from 65 to 200 °C.
- MIL-PRF-46846: This Mil-Spec covers synthetic, rubber, and heat-shrinkable tubing and electrical insulation.
- MIL-I-631: This governs the general characteristics of synthetic resin insulation.
- MIL-DTL-5015: This standard regulates heavy-duty circular electrical connectors that have crimped or soldered contacts.
- MIL-I-3190: This covers flexible sleeving used for electrical insulation.
- MIL-I-7444: This standard covers flexible electrical insulation sleeving.
- MIL-T-83507: This general specification covers electrical connectors, contacts, and cables for tool kits.
- MIL-W-22759: This standard regulates single conductor copper wires insulated with a fluoropolymer and coated with nickel, silver, or tin.
- SAE AMS-DTL-23053: This covers flexible, heat-shrinkable, flame-resistant polyolefin tubing used for insulation and protection for capacitors and resistors.
- MS25274: This specification governs cap, crimp style, electrical wire end, Class I, and Type II connectors.
- MS3190: These connectors are wire barrel, contact, and crimp-type.
- MS3101: This specification covers electric plugs, cable connections, and solder contacts.
Rack & Panel Aerospace Connectors
Rack and panel connectors are specialized types of connectors commonly used in the aerospace and defense industries. They are designed for blind-mate connections, meaning that they can be connected without being able to see the other end of the connection. This is important in critical environments where visual inspection is not possible or reliable.
Rack and panel connectors come in various shapes and sizes but are typically rectangular or circular. They are also available in various pin configurations to accommodate different devices. When choosing a rack and panel connector, it is important to consider the specific needs of the application as well as the environment in which it will be used.
Connectronics carries the RMP Series in 6-, 8-, and 9-pin configurations. Applications of our rectangular multi-pin high-voltage connectors include:
- Electronic counter measures
- Airborne radar
- CRT displays
- Traveling wave tubes
- Low powered lasers
- High-voltage power supplies
- Scientific instruments
The RMP Series of rack and panel aerospace connectors from Connectronics is designed to meet various needs in the military and commercial aerospace markets. The connectors can be ordered as kits for terminating applications or can be terminated with wires of any preferred length.
