A-120 Standard Photoelectric Sensors
Distance-setting Models with a Long 2-m
Sensing Distance Incorporate a Teaching
Function
Sensitivity adjustment without being influenced by back-
ground objects is possible by simply pressing a button. Useful
for teaching without a sensing object.
Easy Optimum Sensing Distance Adjust-
ments
Teaching with and without a sensing object ensures highly ac-
curate detection without influence from the background.
Zone Setting Function
Effective for detecting glossy objects, which were difficult to
detect with conventional sensors. (D-ON)
Select either transistor (NPN/PNP select-
able) or relay output. Three connection
methods (plus a model with a timer func-
tion). Select either a DC power supply or a
variable power
supply: 24 V to 240 VAC or 12 to 240 VDC).

Since the Sensor can have a threshold value not
only in front of the background but also beyond the
background, it is possible to detect objects such as
mirror-surface objects that do not return light from
the object surface.
Teach with only the
background (conveyer).
