High-Performance VLD Bar Code Scanners
(Cat. Nos. 2755-LD4, -LD8)
Read Ranges
2755-LD4 Read Ranges ¬
Minimum Element Width
The high-performance scanners (cat. nos. 2755-LD4, -LD8)
use a visible-laser diode (VLD) for non-contact scanning
applications.
Equipped with either a NEMA Type 1 or Type 4 connector,
their environmentally sealed enclosure is suitable for a
variety of applications. Each scanner has a permanently
attached 3 m (10 ft) cable for connecting to a decoder and a
0.29 m (11.5 in) package detector cable. Extension cables
increase the scanner-to-decoder distance to 7.6 or 15.2 m
(25 or 50 ft).
Features
• Visible-laser-diode scanners
• NEMA Types 1 or 4 connectors
• External package detect connection
• 4 read ranges (2755-LD4); 3 read ranges (2755-LD8)
• 200 scans per second (2755-LD4); 500 scans per second
(2755-LD8)
Compatibility
The high-performance scanners are compatible with the
Enhanced Decoders:
• Single-Head Decoders (cat. nos. 2755-DS1A, -DS4A)
• Dual-Head Decoders (cat. nos. 2755-DD1A, -DD4A)
The High-Performance VLD Bar Code Scanners carry the
following caution:

À Read ranges are based on 4 character, Code 39 labels with a wide to narrow band ratio
of 2.6 to 1 and a print contrast ratio of 0.75 or better. Read ranges will vary with bar
code symbol quality.
Á The glare that results from the laser striking reflective objects (conduit, metal
conveyors) may affect performance of the scanners when used at long ranges. To
minimize this effect, mask the area behind the symbol with a non-glossy material (flat
black paint) or reduce the scan line to avoid reflective objects. Reducing the scan line
will affect reading distances of the scanner.
