An MS connector is a connector that conforms to the MIL-DTL-5015 standard, which is one of the many MIL (Military Standard = MS) connectors that exist among connectors that are used to connect electric wires or between electric wires and electrical appliances.
This is because MIL-DTL-5015 was the first connector standard established in the history of the U.S. military, and therefore the most widely used military connector standard in the industrial world.
MS connectors are used in industrial equipment applications, but they can also prevent wire breakage and momentary disconnection due to vibration and shock, as well as short circuits caused by condensation and high humidity.
They also prevent shorts due to condensation or high humidity. In addition, signal and power wiring can be combined in a single connector, enabling space-saving equipment layouts with high-density multi-cores (up to 128 cores).
On top of that, they are so robust that they will not break even if dropped or bumped a little, and so highly reliable that they can continue to be used without worry even in places where maintenance is extremely difficult.
For this reason, MS connectors are used in a wide variety of fields, including measuring equipment, semiconductor facilities, industrial robots, construction machinery, plants, power plants, mass transit vehicles such as railroads, space equipment applications, outdoor communication equipment, and more.
MS connectors are the original U.S. military MIL standard connectors.
Although designed more than 70 years ago, MS connectors are still widely used in today's high-tech industrial equipment in the 21st century.
The main features and advantages include threaded mating, a sturdy metal housing, a wide array of insert arrangements covering signal to power, and compatibility with a wide range of wire sizes, but the greatest advantage is the worldwide popularity of MS connectors themselves.
MS connectors are said to be the most widespread circular connectors in the world.
Therefore, it is said that even for unidentified industrial equipment imported and exported from abroad, as long as MS connectors are used for the interface, there is almost no need to have trouble obtaining mating connectors.
