General Requirements
ESD
ESD protection has been taken into account when designing the EM20 and the engine is shipped in ESD
safe packaging. Always exercise care when handling the engine outside its package. Be sure grounding
wrist straps and properly grounded work areas are used.
Dust and Dirt
The EM20 must be sufficiently enclosed to prevent dust particles from gathering on the lens and circuit
board. Dust and other external contaminants will eventually degrade the engine
’s performance.
Thermal Considerations
Electronic components in the EM20 will generate heat during the course of their operation. Operating the
EM20 in continuous mode for an extended period may cause temperatures to rise on CIS and decoder
chip. Overheating can degrade image quality and affect scanning performance. Given that, the following
precautions should be taken into consideration when integrating the EM20.

Reserve sufficient space for good air circulation in the design.

Avoid wrapping the EM20 with thermal insulation materials such as rubber.
