Overview
The DF-G1 is an easy-to-use, DIN-rail-mountable fiber optic sensor. It provides high-performance sensing in low-contrast applications.
The sensor’s compact housing has dual digital displays (Red/Green) and a bright output LED for easy programming and status monitor-
ing during operation. The sensor features a single discrete output, either NPN or PNP, by model.
The DF-G1 features increased temperature compensation compared with previous fiber optic sensors. An accessory clamp is available to
secure a bank of connected sensors together on a DIN rail (see
on page 27).

Top Panel Interface
Opening the dust cover provides access to the top panel interface. The top panel interface consists of the RUN/PRG/ADJ mode switch,
LO/DO switch, +/SET/- rocker button, dual red/green digital displays, and output LED.
RUN/PRG/ADJ Mode Switch
The RUN/PRG/ADJ mode switch puts the sensor in RUN, PRG (Program), or ADJ (Adjust) mode. RUN mode allows the
sensor to operate normally and prevents unintentional programming changes via the +/SET/- button. PRG mode allows
the sensor to be programmed through the display driven programming menu (see
on page 3 ). ADJ
mode allows the user to perform Expert TEACH/SET methods and Manual Adjust (see
LO/DO Switch
The LO/DO switch is used to select Light Operate or Dark Operate mode. In Light Operate mode, the output is ON when
the sensing condition is above the threshold (for Window SET, the output is ON when the sensing condition is inside the
window). In Dark Operate mode, the output is ON when the sensing condition is below the threshold (for Window SET,
the output is ON when the sensing condition is outside the window).
+/SET/- Rocker Button
The +/SET/- rocker button is a 3-way button. The +/- positions are engaged by rocking the button left/right. The SET
position is engaged by clicking down the button while the rocker is in the middle position. All three button positions are
used during PRG mode to navigate the display driven programming menu. During ADJ mode, SET is used to perform
TEACH/SET methods and +/- are used to manually adjust the threshold(s). The rocker button is disabled during RUN
mode, except when using Window SET, see
on page 12 .
Red/Green Digital Displays
During RUN and ADJ mode, the Red display shows the signal level and the Green display shows the threshold. During
PRG mode, both displays are used to navigate the display driven programming menu.
Output LED
The output LED provides a visible indication when the output is activated.
Run Mode
Run mode allows the sensor to operate normally and prevents unintentional programming changes. The +/SET/- rocker button is disabled
during RUN mode, except when using Window SET, see
