Vishay Semiconductors VCSEL-Based Proximity Sensors

Vishay Semiconductors VCSEL-Based Proximity Sensors combine compact construction, low power consumption, and highly integrated optical functionality to enable precise distance‑sensing in consumer, industrial, and handheld applications. These devices integrate a vertical‑cavity surface‑emitting laser (VCSEL), proximity photodiodes, signal‑conditioning ICs, and an I²C interface within tiny surface‑mount packages. These features make VCSEL-based proximity sensors ideal for space‑constrained designs.

Vishay VCSEL proximity sensors emphasize stable, high‑accuracy distance measurement through features such as intelligent cancellation to reduce optical crosstalk, sunlight rejection up to high lux levels, and configurable VCSEL driving currents for optimal performance. Many models support advanced interrupt capabilities with programmable thresholds, minimizing host‑processor workload and reducing system power.

The sensors maintain reliable operation across wide temperature ranges and low‑supply‑voltage environments, with optical performance enhanced by the precise emission characteristics of 940nm VCSEL technology. Applications include AR/VR headsets, smartphones, wearables, and general-purpose object‑detection systems, offering designers a scalable portfolio of high‑performance proximity‑sensing solutions.
