General Purpose (Digital Output) Sensors
Description
42FB General Purpose DIN Fiber Optic Sensors are useful in
general purpose or high speed applications. Standard 250s
versions offer extended sensing ranges. High-speed 30s
versions offer a shorter sensing range, but extremely fast
response times for high speed parts counting and assembly
applications.
Each sensor can be directly DIN rail mounted. A separate
mounting bracket is also included for stand alone mounting.
Over 50 compatible standard plastic and small diameter glass
fiber optic cables are available, please refer to the
Allen-Bradley Sensors Catalog.

Indicators
The red output indicator is ON when the detected light level is
above a margin of 1.0. The green stability indicator is ON
when the sensing application is stable, when the detected
light level is below a margin of 0.7 or above a margin of 1.2.

Analog Output Sensors
Description
42FB Analog Output Sensors provide a DC voltage output
that is proportional to the amount of transmitted or reflected
light detected. This sensor has a fast response time and good
temperature linearity as described in the Specifications
below.
Each sensor can be directly DIN rail mounted. A separate
mounting bracket is also included for stand alone mounting.
Over 50 compatible standard plastic and small diameter glass
fiber optic cables are available, please refer to the
Allen-Bradley Sensors catalog.

Indicator
The red output indicator is ON when light is detected. The
intensity (brightness) of the indictor increases as more light is
detected.
