d-sub standard connectors wholesale is usually applied as signal transmission. Signal transmission is divided into two categories: simulation signal transmission and digital signal transmission. Used for signal transmission is mainly to protect the integrity of the transmitted voltage pulse signal, and the transmission speed of the data pulse is much faster than that of the simulated signal, and some data pulses in the electrical connector transmission speed is close to the range of nearly 100 billionths of a second.

When high-speed data signal transmission uses d-sub standard connectors wholesale or cable assembly interconnecting systems, the performance of the connector will vary, importantly the characteristic impedance of the resistance and the crosstalk in the interconnecting system. Cable in the process of use to control crosstalk, because the geometric shape of the resistance is not the same, it is difficult to achieve complete unity, while the size of the connector is gradually getting smaller, which is why the characteristic impedance is particularly important in the process of high-speed data signal transmission, and in the cable, the characteristic impedance is easy to control, However, the length of the cable can cause potential crosstalk, so the control of crosstalk is also important.

In order to correctly select and use d-sub standard connectors wholesale to ensure the reliability of the circuit, when selecting d-sub standard connectors wholesale terminals, the first thing to consider is the electrical parameters of the connector itself. Electrical parameters of d-sub standard connectors wholesale mainly include: rated voltage, rated current, contact resistance and shielding. Rated voltage and current need to be considered, because under the same voltage resistance index, if the use of the environment and safety requirements are different, the high operating voltage is different when used. To limit the rated current, in fact, to limit the temperature rise within the d-sub standard connectors wholesale should not exceed the specified value of the design, it is worth noting that if it is a multi-core electrical connector, to ensure that the temperature rise does not exceed the specified value of the design, the rated current must be reduced.

When selecting d-sub standard connectors wholesale terminals, mainly choose according to the fixed requirements of the outer diameter and shell of the user wire or cable, volume, weight, and whether the metal hose needs to be connected, and some will also have requirements for beauty, shape, color, etc. Select according to the actual demand.
