Datasheet
The A2TPMI is available with different
standard optical cap assemblies with
and without an infrared lens or mirror.
The optics defines the view angle or
field of view (FOV) of the sensor.
The FOV is defined as the incidence
angle difference, where the sensor
shows 50% relative output signal ac-
cording to the setup shown.
