PSC LM520 Details
Compact, Complete Scanning System
Scanner is a compact, decoded, single- line scanner for fixed-
position or embedded applications, such as conveyor, library, document tracking,
chemical and blood analyzers, vending machines, POS terminals, and other attended
or unattended scanning applications.
The LM520 is a complete scanning system, ready to plug in and scan. The LM520
presents a fast, easy and low- cost way to incorporate scanning into any application
where you need to read a barcode.
High Performance, Reliable Scan Module
The LM520 is designed around LM520 Plus scan module. Consistent,
reliable scanning performance is achieved with its retroreflective optical design,
which uses a frictionless, electromagnetic dithering mirror to direct laser
light to its target. This design is highly reliable and consumes less power
than competitive models.
Advanced RapidStart™ circuitry creates the fastest start- of-scan in
the industry, giving snappy performance and a reduction in misreads at start
up An impressive read range, from 2.0 to 36.0 inches (5.1 to 91.4 cm) and excellent
pitch and skew angles makes this scanner suitable for many tightly specified
barcode reading applications.
Rugged Aluminum Enclosure
Measuring only 1.35 x 2.00 x 2.53 inches (3.4 x 5.1 x 6.4 cm) and weighing only
5.4 oz. (153 g), the compact LM520 fits in almost any fixed-position or embedded
application. And the LM520 's rugged extruded aluminum enclosure protects the
scanner from mechanical shock, and seals it from dust and moisture.
Convenient Integration Features
System integration is made easy with the LM520 's unique mounting design. Six
mounting grooves, in the scanner's sealed enclosure, enable mounting on any
one of four sides. A mounting kit, containing special mounting studs and lock
nuts, come with every scanner.
To assure reliable integration, the LM520 uses an industry standard
RS232C interface, which allows the scanner to be mounted up to 50 feet (15.2
m) from the host system. Good read/no read result switches make integration
with other automation control equipment a snap. These convenient design features
help reduce implementation time and the costs associated with developing complicated
Four separate Triggering Modes
Four separate triggering modes can be used to scan a barcode:
- An external switch, such as an output line from a Programmable Logic Connector
- Software commands from the host system
- The LM520 can be set to scan continuously
- The LM520 also uses a unique PSC motion detection technique called LaserSense™
to only scan when an object is passed in front of the scanner.
The various modes are selected via host commands or simple barcode programming
