Laser and CCD Scanners
Wand scanners can satisfy most bar code reading needs. However, we also offer
Integrated Laser Wedge Readers and the Integrated CCD Wedge Reader (complete
WDP Readers built into a laser scanner and CCD scanner) as well as laser and
CCD scanners that plug directly into WDP Reader wand ports. Laser scanners add
these abilities to the WDP Reader:
Fast reading of difficult bar codes.
Reading bar codes from a distance: 1 to 21 inches with Worth Data' model
LZ200, up to 35 feet with the Symbol 3200ER, and typically 3 to 14 inches
with other laser scanners.
Reading moving objects, such as on an assembly line.
No-hands operation. Some scanners can be mounted to turn on automatically
when an object passes under them.
Reading through thick (up to five inches) glass or plastic laminates.
Reading curved surfaces, such as plastic bags of items.
Warning: These laser scanners use low-power, visible-light laser diodes. Although
momentary exposure to the beam is not known to be harmful, the user should avoid
staring directly into the beam, or shining the beam into people's eyes.
These laser scanners are triggered, 5-volt, visible-light, moving-beam scanners
which attempt to read 36 times per second. If the code misreads ten times, you
don't even know it. Non-triggered hand laser scanners are awkward at best. These
laser scanners are the world's best:
Worth Data LZx00 series
These scanners are manufactured by Worthington using the Symbol 1200 Scan
Engine family. They are very lightweight, easy to handle, rugged, and aggressive
scanners on all types of codes and densities. The scan element has a lifetime
warranty. They are tested with repeated drops at 10 ft. to concrete. The cord has a
1,000,000 bend lifetime.
The LZ200 reads at twice the distance most other lasers read -- 1 to 21" with a 4.2
cpi Code 39 bar code or about 15 inches on a 100% UPC Code. The decode is
very quick. The price is $695. The LZ200-WDP is the same laser with the
decoder built into the scanner, thus eliminating the decoder box. The lower cost
LZ100 reads from 1-14" on the same Code 39 code as above and about 10" from
a UPC code. It has a less powerful laser but it is just as reliable and decodes very
quickly like the more powerful LZ200.
These laser scanners use a low-power, visible laser diode. Although momentary
exposure to a CDRH II laser scanner is not known to be harmful, avoid staring
directly into the beam or shining the beam into other people's eyes. The required
safety label to advise the user of the laser cautions appears on these lasers as shown:
