MIL-DTL-5015 Connector: Solutions for Harsh Environment and Industrial Applications

The MIL-DTL-5015 connector is a heavy-duty circular electrical connector with soldered or removable crimp contacts. In addition to being used for power distribution, they can also be used for digital and analog signals.

The MIL-DTL-5015 size connector has a rated operating temperature range of -55°C to 200°C, depending on the connector grade. One disadvantage of the MIL-DTL-5015 connector is that it uses a single keyway, unlike connectors designed according to MIL-DTL-38999. This means connectors can only take polarization by plug-in rotation to prevent misalignment with similar-sized connectors in applications with many plugs and sockets.

MIL-DTL-5015 connectors are available in pin counts ranging from 1 to 104, and the connector’s threaded housing promotes mechanical connections. The specification covers circular electrical connectors with soldered or removable crimp contacts (both front and rear release) used in electronic, power, and control circuits. It can have metal MIL-DTL-5015 or commercial-grade nylon bodies. Male or female contacts can be used in the plug or receptacle-type connector bodies (housings).

Characteristics

• Agency approval: MIL-DTL-5015 (formerly MIL-C-5015).
• Wide Temperature Range: These connectors can operate over a temperature range of -67°F to +257°F (-55°C to +125°C).
• Environment: These connectors can operate under the full range of operating conditions specified in MIL-DTL-5015, and we recommend their use under vibration, moisture, pressure, and temperature extremes.

• Wide variety of contacts: Machined contacts are available in silver or gold plating sizes from 16 to 0. Solder, crimp, PC, and thermocouple contacts are available.

Multiple Matching Options

MS3106 Straight plug

The decisive feature of the MS3106 plug is the coupling ring for mating the socket. The plug has an integrated watertight wire-sealed backshell and cable clamps for strain relief. When disconnecting, it should be sealed with a protective cover to ensure high reliability. It consists of the plug itself, the socket, the plug stopper, and the socket stopper. It can support many different connection polarities and quantities and is easy to insert and remove.

MS3108 Right Angle Plug

The MS3108 plug is a 90-degree plug with a 90-degree backshell for easy cable management. The back shell has a waterproof wire seal and a cable clamp for strain relief. Unlike straight plugs, the 90-degree plug has an L- or T-shaped plug section for vertical and horizontal connections, providing greater flexibility. The MS3108 plug features a ring connector design that ensures stable connectivity and shock resistance. The plug also features a variety of error-proof designs to ensure correct polarity connections and prevent incorrect circuit connections, improving the reliability and safety of the connection. Due to its excellent performance and flexibility, the MS3108 plug has been widely used in connection solutions for various highly reliable electronic devices.

MS3100 Wall Mounting Receptacle

The MS3100 wall mount receptacle comprises the wall mount receptacle itself, the plug, the plug pegboard, and the receptacle pegboard. The MS3100 wall outlet is durable enough to withstand harsh operating environments such as high voltages and temperatures while allowing quick installation and removal. It has excellent shock resistance and connection stability. People use ring connector design to ensure connection performance and stability. Unlike other outlets, the MS3100 wall outlet can easily adapt to vertical floor applications, which is important for scenarios requiring special placement.The MS3100 receptacle provides a flange for panel mounting. It has an integrated watertight cord-sealed backshell and cable clips for strain relief.

MS3102 Box Mounting Receptacle

The MS3102 box mounting receptacle has a flange for panel mounting. Its small rear profile design makes it suitable for installation in tight spaces or without rear housing. Unlike other receptacles, the MS3102 box mount receptacle requires pre-installation in the opening of the equipment case. This makes it ideal for scenarios requiring a fixed connection in a machine or equipment case. It has excellent durability and rust and corrosion resistance. The receptacle is also vibration, slip, and water resistant, ensuring stable and safe receptacle function. MS3102 receptacles are typically designed with ring connectors to support various connection polarities, quantities, and sizes.

MS3101 Cable Connecting Receptacle

The MS3101 is a cable mounting receptacle that connects cables directly to the device. It can support many different connection types and quantities. The MS3101 cable mounting receptacle is easy to install and remove, making it particularly suitable for temporary or frequently changed connection scenarios. It is water and corrosion-resistant and can be used in harsh environments, such as high temperature, low temperature, humidity, and corrosion. The plug can also be designed with a ring connector, ensuring the connection’s stability and reliability.
