Housing Design Considerations

Housing Structure

The housing for the Engine should be wide enough not to put any pressure on the Engine. There should be

sufficient space for the flexible cable and stress release of the cable should also be considered.

Scan Window

A scan window is needed to protect camera lens, aiming light, and illumination lights. This scan window

design should follow:

Hous » ing must not block or shade illumination LED’s, aiming light, and camera lens.

Use high trans » parent and scratch resistant material,such as both side hard coated material. Please refer to fol-

lowing specifications:

Evaluation after 1 minute

dipPing

The gap and angle between housing window and illumination LED (highest point) must ensure that »

the illumination light should not be reflected into lens by window glass.

The window must be perpendicular to the surface of the front plate of the EM3000. »

Temperature

Electrical and other components generate heat. Especially under continuous operation, the temperature of the

Engine will be high. The methods below are for heat concerns:

A radiator on top of the engine is recommended

Do not surround or wrap the Engine by rubber or any material that obstruct the heat dissipation.
