Long Range
Retro-reflective Sensor
VTR24F1
PRODUCT DESCRIPTION
FEATURES
•
•
•
Low Cost
This retro-reflective sensor combines an
infrared emitting diode and unique
photodarlington output to provide high
sensitivity while rejecting ambient light. It has
a very long sensing range (up to 4 inches)
compared to ordinary retros.

•
Detects Low/Diffuse Reflectance
Surfaces
The output of this sensor is activated when a
reflective surface is brought into its field of
view.
The sensor housing is molded polycarbonate
with a slotted flange for easy mounting.
