Operational Current
This section provides the operational current for the ED40 demo board + EA30 @
25° C / 77° F. The maximum operating current increases as the operating
temperature increases.
The values provided in this section are only for the sensor and aimer current on
contact 10.
Note: Power for the illumination LEDs is supplied by current through contacts
20, 21, and 22 as shown in “Imager Connector Contact Assignment” on
page 139 . The peak current for contacts 20, 21, and 22 depend on the
illumination level selected. For an idea of peak current see “” on page 132 .
