DBMM25PK87

D-Sub Connectors refer to the series of IEC-61076-2-101 and IEC-61076-2-106 international standards, and they are widely used in the data transmission and power supply field. They are convenient for connection due to their multiple pins and various interface types. One of the standard type of D-Sub Connector is DBMM25PK87.

Application Field of DBMM25PK87

The DBMM25PK87 is an M series 25 pin female D-Subminiature Connector with a non-keyed pin in a threaded backshell. It is mainly used in the fields like communication, electric automotive, medical equipment, telemeter, national defense and aerospace, and so on. It can be used to connect the internal signal wires in the circuit, or as a power supply interface for the equipment, or act as a connector for certain fitted equipments.

Working Principle of DBMM25PK87

The DBMM25PK87 uses a metal shell with a threaded backshell as the connector sheath, and the shell is solid, strong, waterproof, and features a good heat dissipation performance. Then it applies a spring lever as a locking component to the back cover, and when the cover needs to be assemble or disassemble, it can only be operated through the spring lever. Individually, the contacts can be inserted and removed from the shell with the push-pull structure, so that the contact can be replaced and the wiring is finished.

The contact of the connector is made of pre-plated high-strength pin gold-plated steel. They can provide a good contact with a good wear-resistance performance, and can withstand the external environment, and thus achieve the electrical performance required. The contact tail is fixed mediately by elastomeric bearing, so that the contact in the shell is in good position and contact the shell firmly. The contact connecting parts are designed with quick fit pins in order to achieve a convenient and fast installation.

Finally, the DBMM25PK87 connector has a variety of contact materials, such as claddagh, copper alloy and beryllium copper. They run in accordance with the standards of IEC-61076-2-101 and IEC-61076-2-106, and they feature low contact resistance and good reliability due to their Electrolytic surface plating. In addition, they also possess excellent solder and tin properties for welding processes.
