De scrip tion
The OPB715 series reflective assembly
consists of a GaAIAs LED and a
Photologic
sensor enclosed in an IR
transmissive housing. The sensor is
characterized to detect paper at 0.5"
(12.7 mm). However, the OPB715 has a
wide operating distance range and is
capable of detecting reflective objects at
longer distances. Even low reflectance
materials can be detected at shorter
distances.
The sensor's panel-mount plastic
housing shields stray light and is
terminated with 18" wire leads. The
output can be specified as either TTL
totem-pole or TLL open-collector in
buffer or inverter polarity. The LED is
current limited internally for design
convenience.
