BARCODE-READING REVOLUTION

摘要

The Keyence BL-1300 ultracompact digital barcode reader from Keyence Corp. (Woodcliff Lake, NJ; www.keyence. com) is said to be the first model in its class to use parallel digital processing technology. Noise reduction and compensation functions, only possible with digital processing, overcome the reading performance difficulties of conventional analog circuits. Constructed with diecast magnesium bodies, the IP-65-rated readers are resistant to dirt and harsh environments, and can be easily mounted virtually anywhere.
