Long Range
Retro-reflective Sensor VTR24F1H
PRODUCT DESCRIPTION
This retro-reflective sensor combines an
infrared emitting diode and a unique
photodarlington output to provide high
sensi tivi ty while rejecting ambient light. It has
a very long sensing range (up to 4 inches)
co mpared to ordinary retro s.
The output of this sensor i s 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.
FEATURES
• Low Cost
• Small Package Size
• L ong Sensing Rang e ( up to 4
inches)
• Detects Low/Diffuse Reflectance
