D-Sub connectors have established a long legacy as useful and reliable electrical connectors. The DEMG9SNA197 is among the leading products from this series. This section explains its application field and working principle.

Specifications

The DEMG9SNA197 boasts a wide range of specifications. Its current rating for a single contact is 7.5 Amps, and for the entire insert is 30 Amps. It is ranked NEMA type 12 and 13, with a voltage rating of 600 Volts. With a 7/8-27 UNEF-2A thread, it is highly resistant to physical impacts. It also meets the UL, CSA, IEC, and VDE performance requirements.

Application Field

The DEMG9SNA197 finds application in a variety of industries. Its thread type and current rating make it a good choice for electrical wiring in harsh environments, and its resistance to physical impacts makes it useful in a number of industrial setups. It is often used in aerospace, automotive, telecommunications, and video production.

Working Principle

The DEMG9SNA197 is designed to connect two electrical conductors. It consists of a male and female connector. The male connector has pins which plug into the female connector’s sockets. The electrical flow is possible due to the connection of the conductors. The sockets grip securely onto the pins, resulting in an electrical connection. This connection is highly resistant to shock and vibration.

Construction

The DEMG9SNA197 is constructed with materials such as plastic, metal, and copper. The pins are constructed from copper with gold plating to ensure good electrical contact. The sockets are plastic with gold contact points to ensure a good connection. The threaded portion of the connector is made from metal, typically aluminum or brass, for enhanced durability. Finally, the hardware is made from corrosion-resistant stainless steel to further ensure the connector’s durability.

Installation

The DEMG9SNA197 connectors make electrical connection a straightforward process. The pins are inserted into the female connector, and the connector is tightened down with the threaded portion. Once the connectors are tight, a test of the current flow can be conducted to make sure the connection is good.

Conclusion

The DEMG9SNA197 offers an excellent combination of high current and voltage ratings, and resistance to physical impacts. It is used in a variety of industrial settings, where it provides reliable connections without the need for frequent replacement. Its easy installation and strong construction has resulted in it becoming one of the most popular D-Sub connectors available.
