Mounting Specifications
The 3310 has three M3 x 0.5mm threaded inserts on the bottom of the scanner for mounting with screws.
Mounting General Guidelines
•Avoid specular reflections, caused by ambient and internal light sources.
•The bar code should be slightly off perpendicular to the axis of the scanner.
•To reduce specular reflections the skew angle can vary significantly depending on the application such as: ambient illumination sources, code size and code type.
•Excessive angles should be avoided.
•Other factors, such as surface qualities, mounting distances, secondary windows and external illumination can easily impact these recommendations.
•If a secondary window is used, the window should be mounted as close to the front of scanner as possible at a 90° angle to the optical axis to avoid specular reflections.
•For secondary windows, Honeywell recommends the following:
•Optical quality glass
•>95% transmission in the nominal 650nm wavelength
•
•Avoid window thickness above 2mm
•A skew angle of 15° to 20° between the normal of the bar code's surface and the optical axis of the imager is sufficient to avoid specular reflections.
