Vishay VCNL36758
High-sensitivity medium‑distance proximity sensor
The VCNL36758 is a compact, high‑sensitivity proximity sensor from Vishay that integrates an infrared emitter and photodiode into a single surface‑mount package. Designed for medium‑distance detection, it offers reliable performance thanks to intelligent background light cancellation and programmable interrupt thresholds, enabling efficient power management in embedded systems. Its small 5.0 × 2.0 × 1.5 mm footprint makes it well‑suited for space‑constrained designs in modern consumer and industrial electronics.
Key features
- Integrated IR emitter (940 nm) + proximity sensor in a single package
- I²C (SMBus‑compatible) interface for easy control and data readout
- High sensitivity with intelligent crosstalk and ambient light cancellation
- Programmable high/low interrupt thresholds for MCU power saving
Applications
- Collision detection in robots or toys
- Lighting control in buildings and public spaces
- Parking space detection, smart lavatory appliances
- Screen activation in home appliances
