New Yorker Electronics Stocks Vishay’s New Fully Integrated Proximity Sensors

New Yorker Electronics has introduced two fully integrated proximity sensors from Vishay Optoelectronics. These sensors, designed to increase efficiency and performance in consumer and industrial applications, feature an IR emitter and a vertical cavity surface-emitting laser (VCSEL), respectively.

VishayThe 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. The smaller packages at lower cost are ideal for space-constrained battery-powered applications.

The proximity sensors released by New Yorker Electronics are geared toward space-constrained battery-powered applications. One important application is detecting whether or not users are wearing ear pods or virtual reality / augmented reality (VR / AR) headsets. With ranges to 300mm, they also provide collision detection in toys and consumer/industrial robots. The VCNL36821S and VCNL36826S feature low power consumption down to 6µA 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. The proximity sensors use intelligent cancellation to eliminate cross-talk, while a smart persistence scheme ensures accurate sensing and faster response time. The IRED and VCSEL wavelengths peak at 940nm and have no visible “red-tail.”

The VCNL36821S and VCNL36826S offer excellent temperature compensation from -40 °C to +85 °C, and have a Moisture Sensitivity Level (MSL) of 3 — in accordance with J-STD-020 — for a floor life of 168 hours. The sensors are RoHS-compliant, halogen-free, and Vishay Green.

Samples and production quantities of the new VCNL36821S and VCNL36826S are available now, with lead times of eight to 12 weeks for large orders.

New Yorker Electronics is a franchise distributor for Vishay Dale and carries its complete line of discrete semiconductors (diodes, MOSFETs and infrared optoelectronics) and passive electronic components (resistors, inductors and capacitors).
