Mounting Specifications
The 3330 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
• Anti-reflective coating on both sides
• 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.
