Enclosure Specifications The IS4800 laser scan engine series was specifically designed for integration into custom housings for OEM applications. The scan engine’s performance will be adversely affected or permanently damaged when mounted in an unsuitable enclosure. Note: THIS DEVICE DOES NOT COMPLY WITH 21 CFR 1040. USE ONLY AS COMPONENT. The limited warranty (on page 37) is void if the following considerations are not adhered to when integrating an IS4800 series scan engine int

Flex Cables Note: To ensure optimum engine stability, use the flex cables shipped with the scan engine. The host flex cable is used to carry power and data signals between the engine and the host system. The flex cable should allow for a minimal voltage drop and maintain a good ground connection between the host and the engine. In terms of grounding and voltage drop, a shorter cable is better. The 10-POS flex cable used to connect the engine to the host or the engine to the decode PCB

Beam Clearance • Keep the scan engine’s beam sweep free from obstructions. For detailed information on the exit beam angle and location, please refer to Exit Beam Specifications on page 9. • A dark matte-finish on the internal walls of the housing can be utilized to avoid internal beam reflections. Output Window Properties Note: Contact a customer service representative to coordinate the best window material required to maintain laser safety requirements for your application. An im

Output Window Coatings • Anti-Reflection An anti-reflective coating can be applied to the inside and/or outside of the window to reduce the possibility of internal beam reflections interfering with the scan performance of the engine. If an anti- reflective coating is applied, it is recommended that it be on both sides of the window providing a 0.5% maximum reflectivity on each side from 640 to 690 nanometers at the nominal window tilt angle. The coating must also meet the hardness adhe
