Vishay Intertechnology’s VCNL36758 proximity sensor debuts in a 5 mm x 2 mm x 1.5 mm surface-mount package. Integrating an IR emitter, photodiode, amplifiers, and a 12-bit ADC in one device, the component exhibits low power consumption and medium distance proximity detection up to 600 mm.
The sensor’s IR emitter drive is via an integral current sink with a selectable register, allowing designers to optimize detection range and power consumption. Also, a programmable interrupt function allows them to specify high and low thresholds, reducing continuous communication with the microcontroller and lowering system power consumption. Operating over a temperature range from -40°C to +85°C, the VCNL36758’s emitter wavelength peaks at 940 nm with no visible red-tail.
Samples and production quantities are available now, with lead times of 16 weeks. Pricing for US delivery starts at $0.80 each. For greater gleanings, procure and peruse the VCNL36758 datasheet.
