VCNT2030 Reflective Optical Sensor with VCSEL and Transistor Output

Vishay's reflective optical sensors are ideal for industrial, computer, consumer, and mobility applications. Saving greater than 40% of PCB space compared to previous-generation solutions while delivering improved performance with a higher current transfer ratio (CTR), increased sensing distance, and lower power consumption, Vishay's VCNT2030 features a vertical-cavity surface-emitting laser (VCSEL) and a silicon phototransistor in a miniature 1.85 mm x 1.2 mm x 0.6 mm surface-mount package. The VCSEL’s narrow emission angle enhances internal crosstalk suppression and improves proximity performance, even behind cover glass. The VCNT2030 offers a remarkable sensing distance of 15 mm, which is three times greater than the closest competitor. Its low 8 mA driving current significantly reduces power consumption, maintaining the same performance level as 20 mA infrared emitters. The sensor features a detection range of 0.3 mm to 6 mm (well-suited for precise sensing applications) and a typical CTR of 31% which is over 100% higher than previous solutions.
