Vishay – Light Barrier

Vishay_July2014_pg13CVishay-logo
Using Vishay’s fixed gain IR receivers to receive the light and infrared emitters to emit the light, a light barrier system can be added to any application. With a fixed gain, the detection threshold and resulting detection distance are fixed. Once the design of the optical parameters is determined, the sensor will have stable, repeatable performance under all lighting conditions.
