AV500 2D CAMERA
Applications
The AV500 cameras are specifically designed for industrial applications requiring high
reading performance such as:
• Low aspect ratio barcodes
• Codes covered by plastic film
• Codes located within a large depth of field
• Codes within a wide field of view
• High resolution codes positioned at far distances from the barcode reader
• Fast moving objects
The AV500 is designed for multi ‐ head arrays, single side or multi side tunnels and hybrid
configurations. It can also be used as a stand alone unit.
Stand Alone Presentation Scanning
Manual Presentation Scanning
In Manual Material Handling or Parcel Scanning applications, manual presentation scan ‐
ning is often the preferred method for item identification. Maximum productivity and
operational efficiency is maintained, while the stationary overhead reader continuously
scans the working area, the operator can easily and quickly handle objects of various
dimensions and weights. Since no point
‐ and ‐ shot is required for scanning, no extra tools
or infrastructure is necessary in the working area; no extra operations for part identifi ‐
cation other than passing the object through the scanning zone. No training is required
for users. The large coverage area and fast acquisition rate – by AV500 – permits rapidly
handling objects in sequence with great tolerance. White illumination and continuous
high power mode enable top performance with the maximum comfort for operators.
Single or Multi-Unit Tunnels and Arrays
Many AV500 reading system applications will read over a moving conveyor and use a
network of multiple devices.
• Optical Encoder Wheel (Tachometer): Used underneath a conventional conveyor.
The encoder generates a pulse per specified distance (mm [in]) of conveyor travel.
• Internal Tach: This is a software ‐ generated pulse mimicking an encoder/tachome ‐
ter.
