ED40 Decode Board Integration Guide 123
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.
