Optical Sensors

Aratas Optical Sensors utilize a silicon potting structure on the LEDs that are inside the photomicrosensors. This design reduces any mechanical stress applied to the LED and strengthens the physical integrity of the LED chip. The construction also produces an LED that maintains higher brightness for a longer period of time. Aratas offers a wide range of non-amplified photomicrosensor products, giving engineers the choice of reflective or transmissive types with different configurations, mounting styles, sensing distances, and slot widths.
