Industrial Secure Digital (SD/SDHC) Memory

Delkin industrial rugged secure digital

While Secure Digital has been a reliable, commercial storage format since 1999, Delkin Devices takes SD to the next level with rugged, industrial-grade cards that excel in extreme environments. Delkin industrial SD and SDHC cards are built with single-level cell (SLC) flash, delivering industrial temperature ranges, greater endurance and faster data transfer.

Selection of Delkin’s industrial SD card for embedded memory results in faster time to market and lower sustaining engineering costs over the life of the product.  This is accomplished through reduced initial design time to integrate this widely accepted form factor and Delkin’s controlled bill of materials, which ensures a consistent solution and guaranteed performance over time.
Delkin Devices SLC SD cards are available in Commercial (0 to 70°C) and Industrial (-40 to 85°C) product grades, in capacities from 128MB to 8GB.  Delkin also offers SD and SDHC cards with multi-level cell (MLC) NAND flash, as an economical solution for applications in less demanding operating environments.  Delkin SD Cards are built to order and are configurable with custom labels, laser etched serial numbers, CID product name and special packaging. 

Delkin Devices manufactures rugged industrial grade Secure Digital with industrial temperature components, and enhanced shock and vibration performance. Control of each memory card's performance is assured by a configurable part number and a locked down BoM, minimizing the prospect of unscheduled field inspections and product replacement.
