Rectangular Connectors - Housings is a type of electrical connector. The DMC-MD 40 B 56-01 is one such type, with its applications and working principle outlined below.

Application

The DMC-MD 40 B 56-01 is a rectangular connector housing. It features a low-distortion terminal-displacement system, making it suitable for home and professional audio gear as well as other audio and video equipment. It is also used in high-power systems such as power-over-Ethernet (PoE) applications or other systems requiring high current and strong electrical connections. Its design includes a high level of protection from electromagnetic interference (EMI) for applications in which radio-frequency interference (RFI) is a concern.

Working Principle

The DMC-MD 40 B 56-01 operation is based on the principle of contact displacement. The contact elements of the housing are pushed against a mating contact on the inside surface of the connector. This ensures the contacts are warmly connected in the terminal housing before being firmly secured in place. The spring force of the contact elements combined with the snap-lock design ensures that once connected, the contact elements are kept in place and are prevented from becoming loose during operation.

The contact displacement principle is also used with its assembly. During assembly, a force needs to be applied onto the contact elements to ensure the proper contact between the connector and its mating partner. This force is provided by spring-loaded arms that fit into the grooves of the housings. When the arms are fully inserted into the grooves, they are “locked”, thus providing the necessary force. The force of the spring-loaded arms helps to make sure a tight connection is formed between the housing and the contact

The DMC-MD 40 B 56-01 achieves a very high level of contact integrity as a result of its design. It has also been tested for high voltage and experiences no spark, thus making it suitable for use in a variety of environments.

Conclusion

The DMC-MD 40 B 56-01 is a rectangular connector housing that uses contact displacement and spring-loaded arms to achieve a very high level of connection fidelity. It is suitable for use in home and professional audio and video equipment, power-over-Ethernet (PoE) applications, and other high-power applications in which EMI is a concern. Its snap-lock design prevents contact elements from becoming loose during operation, and its insulation is rated for high voltage. As a result, the DMC-MD 40 B 56-01 is an ideal solution for robust and reliable electrical connections.
