A 21-pin ZIF connector on the SE4750 connects the engine and the host device via a 55 mm flex (available from
Motorola). For information about this connector, see
Figure 4-3 on page 4-5
A Visible Laser Diode and associated optics (aiming element) generate an aiming pattern, and dual, high output
LEDs provide illumination for the imager under virtually any lighting condition. The aiming subsystem, illumination
system, and frame rate are under dynamic software control.
The primary component of the SE4750 imager is a 1/3" format CMOS 1280 H x 960 V monochrome digital image
sensor. The CMOS sensor converts photons to a digital representation (8 bits per pixel) of the image present on
the sensor.
