MS3106A28-21S is an automatic connector series product designed and manufactured by Amphenol. It is a circular environmental plug, which has the characteristics of small size, good waterproof performance, fast locking and anti-mechanical interruption. MS3106A28-21S is suitable for use in severe conditions. It can meet the requirements of waterproof, light, shock and vibration. The connector is widely used in field applications such as aerospace, communication, shipbuilding, military, medical, home automation, computers, remote control and other industrial control fields.

The MS3106A28-21S uses a three-piece contact system consisting of an insert with spring-loaded contacts, an insulator and a threaded housing. The insert and the insulator are combined into one unit by pre or post-welding. The mating surface of the insulator is equipped with an integral thread. When the connector is connected, the spring-loaded contact first contacts the corresponding terminal\'s mating contact point and is latched under the action of a positive stop spring. At this time, the contact has the proper contact force to ensure reliable contact.

In addition to the latch connection mechanism, the MS3106A28-21S also includes a number of other features designed to ensure reliable mating. For example, the connector is equipped with a bayonet locking mechanism. The bayonet is designed to provide additional contact force to ensure a reliable connection. It consists of a bayonet, a bayonet spring, and a key-operated contact carrier. The spring presses the bayonet back into the slot before it is locked. When the connector is rotated, the bayonet seal under the action of the bayonet spring is pushed forward and connected.

The insulation system of MS3106A28-21S mainly includes a rubber seal and a polytetrafluoroethylene (PTFE) seal. The rubber seal is used between the contact and the housing of the connector and provides a seal in the radial direction. The PTFE seal is connected between the contact and the housing, and combines with the rubber sealing system. This seal is used to prevent the migration of water vapor or contamination into the contact area.

The insert of the MS3106A28-21S connector is designed with double contact points that are 0.60 inches apart, which ensures a reliable connection and good transmission between contacts when the connector is mated. The contact arrangement of the connector ensures that a low inductance parallel short circuit is formed between the corresponding terminals of two mated connectors. In addition, the contact terminals have a maximum current rating of 12 amps.

The MS3106A28-21S is designed and manufactured with modern processes and materials, and meets the requirements of IP68 protection when mated. The locking nut and gasket system provides excellent mechanical and environmental protection. This connector is resistant to vibration, shock, temperature extremes, humidity, salt water etc.

In summary, the MS3106A28-21S connector is a high-performance, high-quality environmental connector developed to meet the increasingly stringent requirements of various application fields in the modern home automation, industrial equipment and military fields. This connector has the advantages of fast installation, waterproof performance, high contact reliability and environmental protection, and provides highly reliable connection solutions for harsh working conditions.
