De scrip tion
The OPB690 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
transistor output between states that can
readily drive logic gates.
This switch is designed to easily snap
mount into a 0.037" 0.001" (0.94 mm)
thick material with a rectangular opening
of 0.320" 0.003" x 0.472" (8.13 mm x
11.99 mm) minimum. Insertion into the
punched side of metal is recommended.
Customized lever arms and spring
torques can be designed for specific
applications.
