Omron F3C-AA42 DATASHEET

Distance settable Photoelectric Sensor for conveying applications

F3C-AA42-@@

• Background influences are eliminated
by a unique optical system for setting
the detection distance

• Small black-/white-error

• Sensing distance mechanically adjust­able:
BGS setting distance: 150 - 900 mm
Detecting distance: 0 - 750 mm

• Small housing-case specially de­signed for conveyer-application (only
8 mm of thickness on the top of the
housing)

• Minimal blind-zone through additional
receiver

• Sensitivity adjustment for near side
detector

• Integrated jamming control unit
(Only F3C-AA42-3J)
