M.2 key M SSD To PCIe 3.0/4.0x1 PCI-Express Adapter Riser Card Flexible Flat Cable for M2 NVMe Solid State Drive Extension Cable

What is the functional difference between R14SF 3.0 and R14JF 4.0?

Product Model：R14JF 4.0/R14SF 3.0

Product Name:for M.2 NVMe SSD to PCI-E X1 signal adapter cable

Cable length: 15cm,25cm If you need other length, please contact us to change the price.

Speed bandwidth: PCIe 3.0/4.0 x1 (measured PCIE4.0 read/write about 1400MB/sec, PCIE3.0 read/write about 700MB/sec)

Product function: Industrial control server equipment connection, PCIe signal high-speed transmission.

Restrictions on use: Only for professional engineers to specify the purchase.

Purchase tip: Be sure to buy 1~2 samples first to test and verify that they are correct before purchasing in bulk.

Tips: This product is compatible with many problems, incorrect assembly or improper operation will burn your equipment. Purchase is limited to professional engineers. This product is a bespoke product and is non-returnable and non-exchangeable. Please consider and confirm clearly before placing your order. This product has many restrictions on use, does not support WiFi wireless cards, does not support WWAN, and only supports NVMe M.2 key M SSD cards.

Length Note: The length of the cable refers to the length of the cable and does not include the PCB or connectors.

Product Advantages:

1. Cable advantage, support PCIe 3.0/4.0 full speed stable transfer.

2. Cable length advantage, from 3cm to 1m can accept customization.

3. No over-hole design for differential signals, no parasitic capacitance or inductance for signal attenuation interference, no CAF micro-short circuit phenomenon, durable products.

4. The product uses high quality materials, PCB workmanship is precise, copper thickness is thickened to 1oz, gold finger plating content is sufficient, gold plating sufficient conductive performance, can reduce the oxidation of rust impedance caused by the rise of the dead blue screen.

5. The wire used in the product is already very durable, and the metal solder joints are protected by PCB spacers of 3mm thickness, and locked with screws and hexagonal nuts for fastening. The product is robust and reliable, resistant to pulling and tugging, and will not have problems with broken wires and dropped nails. The wire can be bent or folded without affecting its use.

6. The PCB is shortened and fattened, the shortening will not jam the card, and the fattening and lengthening design makes the board easier to install and reduces the chance of damage.

Caution:

1. When plugging in the wires, be sure to identify the direction, do not plug in the opposite direction or plug in the wrong position to prevent burning the equipment. When plugging in, hold the socket of the device before plugging in the wires to avoid breaking the socket pins with excessive force. Bending and pulling is prohibited within 2cm of the soldering of the cable to the board.

2. The board or motherboard is an electronic device that will age and oxidise over time, so connecting the extension cable will only make it more unstable. Older equipment is not supported. Equipment older than 3 years. Please do not buy.

3. Purchased by product engineers only, for product testing purposes only, other uses, please do not purchase.

4. Support universal version of M.2 NVMe SSD, not support M.2 WiFi wireless NIC, not support M.2 SATA, not support Lenovo-compatible/HP-compatible network card.
