Photo IC Photointerrupter
Voltage regulator
Model No: LBP-122
Description
The LBP-122 series are slotted optical switches designed for multipurpose non contact sensing. They
consist of a GaAs LED and a silicon optical IC. Sensor packaged in an injection molded housing and
facing each other across a 5mm(.197inch) gap.
Features
