General Requirements
ESD
ESD protection has been taken into account when designing the EM20-M37. However, due to limited board space,
additional ESD protection, such as TVS protection, is not provided on the engine’s I/O interface. It is advised to take
corresponding protection measures when integrating the engine.
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-M37 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.
Ambient Environment
The following environmental requirements should be met to ensure good performance of the EM20-M37.
