MALVERN, PA — Vishay Intertechnology, Inc. (NYSE: VSH) introduced a compact proximity sensor designed for smart home, industrial and office devices that require longer-range detection in space-constrained hardware designs.
The new VCNL36758 sensor combines an infrared emitter, photodiode, amplifiers and a 12-bit analog-to-digital converter into a single surface-mount package measuring 5.0 mm by 2.0 mm by 1.5 mm.
According to Vishay, the device supports proximity detection at distances up to 600 millimeters while reducing package volume by 65% compared with earlier-generation products.
The sensor is intended for applications including display activation in printers and appliances, collision avoidance systems in robots and toys, occupancy-based lighting controls and parking space monitoring systems.
Vishay said the device incorporates background light cancellation technology intended to maintain sensing performance under ambient lighting conditions, while programmable interrupt functions and single-command measurement modes are designed to reduce system power consumption.
The sensor also includes crosstalk cancellation and adjustable persistence controls intended to minimize false triggering in proximity detection systems.
The VCNL36758 operates at temperatures ranging from minus 40 degrees Celsius to 85 degrees Celsius and uses a 940-nanometer infrared emitter without visible red light emission.
The company stated the sensor is offered in a lead-free, RoHS-compliant package.
