- CONTEC 4GB SD Card SD-4GB-A
With its compact size, it corresponds to 100BASE-TX in eight all port. 2-way power connector and reverse wiring protection within
This SD card is a SLC (Single Level Cell) type NAND flash memory suitable for industrial applications.
4GB SD Card
Model:
SD-4GB-A
Maker:
CONTEC Co., Ltd.
Features
- Conforming to the SD Memory Card standard.
- Containing no rotating or moving part as in hard disk drives, thus best suited for applications which require high environmental resistance (to temperature, humidity, vibration, shock) and for continuous operation for extended periods of time.
- Never making any sound such as motor rotation sound or access noise during seeking, thus best suited for applications which require complete silence.
- Featuring greater reliability, writing sequences, and increased number of rewriting with SLC (Single Level Cell), NAND type flash memory, it is more suited than MLC (Multi Level Cell) for industrial applications.
- Power consumption is reduced by eliminating a rotating or moving part.
