Fea ures
Phototransistor output
Mechanical switch replacement
Printed circuit board mounting
Enhanced signal to noise ratio
Lever force options
De scrip ion
The OPB680 consists of an NPN
phototransistor and an infrared emitting
diode in a molded plastic housing. The
phototransistor has an enhanced low
current roll-off which improves contrast
ratio and immunity to background
irradiance. A lever arm actuated flag
interrupts the light beam, switching the
output between states that can readily
drive logic gates. The lever can be
actuated by a passing paper sheet
without damaging the paper edge.
The OPB680-20 has the same features
as the OPB680 with an increased lever
operating force. This feature prevents
false triggering due to incidental contact
in door sensing and other heavy duty
applications.
Customized lever arms and additional
spring torques can be designed for
specific applications.
