4.1 Setting up the bar code scanner
The CLV640 Bar Code Scanner consists of a laser scanner (laser diode and lens) with dy-
namic focus position and an electronic unit with an integrated decoder. The laser scanner
and electronic unit are located in a housing. The light exits and enters via a reading window
in the industrial-type housing. The bar code scanner (depending on the version) is electri-
cally connected by a cable with a connector or a revolving connector unit with two connec-
tions.
For an adaption to on-site space conditions/reading functions three housings are available:
a housing with front reading window, a housing with side reading window and a housing with
oscillating mirror. Via the integrated angle attachment/oscillating mirror, the laser beam ex-
its through the side reading window at an angle of emergence of 105°. For the oscillating
mirror this corresponds to the central position (default settings) of the laser beam perpen-
dicular to the scan direction.
