TTI, Inc., is now stocking the VCNL36821S/36826S proximity sensors from Vishay.

Vishay Intertechnology, Inc. introduced two new fully integrated proximity sensors designed to increase efficiency and performance in industrial, medical and commercial applications. Featuring an IR emitter and a vertical cavity surface-emitting laser (VCSEL), respectively, the Vishay Semiconductors VCNL36821S and VCNL36826S each combine a photodiode, signal processing IC, and 12-bit ADC in a compact 2.55 mm by 2.05 mm by 1.0 mm surface-mount package.

Compared to previous-generation devices, the proximity sensors released today offer smaller packages at a lower cost, making them ideal for space-constrained battery-powered applications. With ranges to 300 mm, they also provide collision detection in vacuums, consumer and industrial robots. The VCNL36821S and VCNL36826S feature low power consumption down to 6 µA to increase efficiency in these applications.

The devices support the I2C bus communication interface for easy access to the proximity signal, while their programmable interrupt function allows designers to specify high and low thresholds to reduce the continuous communication with the microcontroller.
