Theory of operation
The H3275 LED Light Source is used as a backlight for an
optical sensor or camera in a web or strip guiding system. The
H3257 provides uniform LED light output through a diffusing
lens, which is captured by a sensor or camera to provide
information about the material position. The device can be
configured to emit 7.5 kHz light (pulsed) or DC light.
Factory-calibrated LED intensity levels can be easily selected
by actuating a pushbutton switch. An internal dry-contact
relay indicates the status of the light source.
