What Are The Differences Between Rectangular Heavy-duty Connectors And Circular Heavy-duty Connectors?

What's the difference between rectangular heavy duty electrical connectors and circular heavy duty power connectors?

The two heavy duty connector 24 pin units can be identified by their appearance: one is square, and the other is circular or rectangular. The fundamental difference lies not in this, but in the usage environment of 16 pin heavy duty connector. For example, the same 100-pin aviation socket, the round 24 pin heavy duty connector is larger in size and occupies more space. The rectangular 4 pin heavy duty connector arrangement has a high density, uniform distribution, small size, and light weight. Another common application is that the socket is fixed to the panel, and the contact parts of the 6 pin heavy duty connector can be directly soldered to the printed circuit board, which is convenient and aesthetically pleasing. The PCB is connected parallel or perpendicularly to the corresponding socket, generally used for wiring connections in small instruments and equipment. Other aspects such as sealing, shielding, waterproofing, and filtering can be addressed; the customer decides based on their specific needs.
