So what are the key points to pay attention to when choosing a D-SUB high current connector? Here we will explain to everyone.

1. Current requirements.

Firstly, it is necessary to understand the carrying current and voltage requirements of the high current D-SUB connector contacts. The current carrying capacity of a connector is usually determined by the size of the wire and the contacts, and the rated voltage is determined by the contact spacing and insulation material. Therefore, it is necessary to ensure that the contacts meet the size of the supporting conductor to avoid overheating.

2. Data table.

It is very important to understand how connector manufacturers specify the rated current and working voltage of their products. The level and data can refer to the manufacturer's standards, but the usage standards of different manufacturers vary greatly. Therefore, when checking the current rating, the first thing to observe is the temperature rise specification of the connector, which indicates the heat dissipation value of the high current D-SUB connector at a specific current value.

3. Termination type.

Due to the various termination types of connectors, the use of welded contacts helps to prevent dust and moisture from entering. The other is crimping, which is convenient for on-site maintenance, such as compressing terminals, making wire wound connections, direct connections, loop connections, eye shaped connections, etc. In addition, the type of termination required for the connector depends on the size, type, voltage, and current of the cable.

4. Mechanical and environmental performance.

Due to the influence of various application environments such as moisture, temperature, vibration, and impact on the use of connectors, it is necessary to be very cautious when selecting high current D-SUB connectors, clarify the mechanical, environmental performance, and housing type of the high current D-SUB connectors, ensure reliable connectivity, and avoid the influence of adverse factors such as short circuits.

5. Cost status.

Due to the fact that the price of high current D-SUB connectors is mainly determined by the hardware itself, as well as the manpower and materials required for assembly and maintenance. Therefore, do not seek small gains. Choosing an inexpensive high current D-SUB connector must be determined based on multiple factors such as cost.
