The MDM-9PSA-A172 connector is known as one of the most important members of the D-Sub connectors family. This connector is a hooded style sub-miniature, Metric, Circular connector series specificially designed for harsh environments. It meets the stringent requirements for operating in adverse conditions for applications in Medical, Automotive, Industrial, Metro, and Military Industries.

The MDM-9PSA-A172 sits between the MDM-xPSA-A series and the MDM-SPSA-A series, having the characteristics of both series. The major differences between the MDM-9PSA-A172 and the MDM-xPSA-A series is in two aspects. Firstly, the MDM-9PSA can take up more current than the MDM-xPSA series. Secondly, the MDM-9PSA-A172 has a higher contact retention force with lower insertion and extraction forces.

The MDM-9PSA-A172 connector can come with several insert arrangements varying between 2, 4, 6 and 9 pins. It has a maximum operating voltage of 250V rms and a 350V working insulation voltage. The connector is waterproof and resistant to vibrations, shock and compression. The material used in their construction is stainless steel housing, and a stainless steel contact within a PTFE insulating sleeve.

The MDM-9PSA-A172 connector follows the international IEC 60130-9 standard. It is designed for a wire-to-wire configuration and has a robust coupling nut which allows it to be mated and demated up to 200 times. It is an IP68 rated connector, meaning it is water and dust proof and can be submerged up to a depth of two meters.

The working principle of the MDM-9PSA-A172 connector is quite simple. It works by creating a connection using a contact between two electrical circuits. The contact is housed in a metal connector body. The body contains a number of small pins that fit into a socket on the opposite side.

When the two connectors are mated, the pins create a mechanical bond between them, creating an electrical connection. The contact has two contact points: one on each side of the socket which makes electrical contact when mated. The contact also provides a seal which prevents foreign objects from entering the socket and disrupting the connection.

The signal transmission and power cables of the MDM-9PSA-A172 are designed to resist a wide range of environmental characteristics. In addition, the shear force, tensile force and vibration shocks are also resistance to prevent damage to the connectors. This makes the MDM-9PSA series ideal for space and marine applications which require tight sealing and reliability.

The MDM-9PSA-A172 connector offers a cost-effective solution for high durability and reliability. With its water tightness, and robust mechanical design, it can be used in a wide variety of applications including marine, Military, Industrial, Aerospace, Automotive, and Medical applications.
