ADT Product Descriptions

Summary of technical issues:

What is the quality of the wire? Is there a shield?

No metal shielding, using advanced EMI shielding conductive polymer, new materials for EMI shielding, flat cable design. This technology allows each cable to be completely covered by an electromagnetic interference shield of conductive polymers to prevent incoming or outgoing electromagnetic frequency emission, minimize interference and performance degradation, and reduce product weight.

Is the wire soft? Does it bend?

The wire is SD high-speed dedicated wire with a thickness of 1.4mm. Strong and durable, so the wire is harder. The connection between PCB board and wire can not be bent, and the middle section of other wire can be bent and folded, which does not affect the use.

How compatible is the SD extension cable?

Line length up to 80cm can support ordinary card full speed without I characters

The line length within 30cm can support UHS-I full speed, 80cm can support UHS-I half speed

The line length within 80cm can support UHS-II, UHS-III full speed, SD card will have the speed mark. As shown below

SD extension cable using SD UHS-II high-speed card speed measurement, 100% test PASS before release. As shown below

The dashed line is the speed measurement of the UHS-II high-speed card, the SD card marked value is 300MB/s, and the actual speed is about 250MB/s

Does it support hot swap?

It does not support hot swap. You need to shut down the device before installing an SD extension cable.

What specifications and models of connectors are available?

The store has a full series of SD card connectors, and the following connectors can be arranged in any combination and can be customized.
