Vishay Intertechnology’s New Cost-Effective Proximity Sensor Provides Sensing Distance Up to 30 cm
Device Provides Object and Collision Detection for Consumer and Industrial Applications
MALVERN, Pa., Sept. 16, 2019 (GLOBE NEWSWIRE) -- The Optoelectronics group of Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new proximity sensor that offers a sensing distance of up to 30 cm. Combining an IR emitter, photo detectors for proximity, amplifiers, and ADC circuitry into a single package, the Vishay Semiconductors features a programmable interrupt function and supports the I²C bus communication interface for efficient object and collision detection in a wide variety of consumer and industrial applications.
Ideally suited for use in smart home, industrial, office, and toy products, the device released today provides a 33% increase in proximity detection distance compared to previous-generation sensors at a lower cost than similar solutions on the market. Applications include presence detection to activate displays in printers, copiers, and home appliances; collision detection in robots and toys; vehicle occupancy detection in parking lots; and proximity detection in lavatory appliances.
The VCNL3040’s programmable interrupt function allows designers to specify high and low thresholds, which reduces the continuous communication with the microcontroller. Featuring selectable 12-bit and 16-bit outputs, the proximity sensor uses intelligent cancellation to eliminate cross-talk, while a smart persistence scheme ensures accurate sensing and faster response time. The emitter wavelength peaks at 940 nm and has no visible “red-tail.”
The device offers a supply voltage range of 2.5 V to 3.6 V, an I²C bus voltage range from 1.8 V to 3.3 V, and excellent temperature compensation from -40 °C to +85 °C. Offered in a lead-free 8-pin QFN package, the sensor is RoHS-compliant, halogen-free, and Vishay Green.
Samples and production quantities of the new VCNL3040 are available now, with lead times of eight to 12 weeks for large orders. Pricing for U.S. delivery only starts at $0.70 per piece in 5,000-piece quantities.
