Recently, Vishay Intertechnology, Inc. announced that the Optoelectronics Division has released a new high-sensitivity proximity and ambient light sensor with a detection range of up to 1 meter. 
---VCNL4100. The Vishay Semiconductors VCNL4100 combines high-power infrared emitters, proximity and ambient light photodetectors, signal processing ICs and 8-bit/16-bit ADCs in FiltronTM technology and a small 8mm x 3mm x 1.8mm surface mount package. . This three-in-one sensor With interrupt function, support I2C bus communication interface, can be used for smart home, industrial and office equipment.
The VCNL4100's detection range is five times higher than that of previous generation devices and can be used in printers, copiers and household appliances to activate displays when objects are detected; anti-collision of toys and robots, lighting control in offices, corridors and public buildings, Activate the toilet kit and check the occupancy of the parking space in the parking lot. sensor Integrating the circuitry required for these applications into a single device requires no additional gratings and does not require the IR emitters and photodiodes to remain aligned. The small form factor of the device helps save space and gives engineers more flexibility in designing sensors Placement and placement.
Ambient light and proximity sensor for the VCNL4100 Working in a parallel structure, each sensor There is a programmable interrupt function that reduces power consumption through high and low thresholds. The device's Filtron technology achieves ambient light spectral sensitivity close to the human eye and has a good ability to eliminate background light.
The VCNL4100's built-in ambient photodiode has a detection range from 0.01lx to 5.2klx, allowing the device to operate in applications with black or high transparency lenses. Sensor with 16-bit ADC It is not affected by the flicker of fluorescent lamps and has good temperature compensation in the range of -40 °C to +85 °C. 8-bit proximity sensor for the VCNL4100 Smart cancellation technology eliminates crosstalk, while clever continuous design ensures accurate detection and faster response times. The transmitter has a peak wavelength of 940 nm and no visible "red tail".
The device's supply voltage is 2.5V to 3.6V, and the I2C bus voltage is from 1.8V to 3.6V. sensor It is available in a lead-free 10-pin molded package that is RoHS and Vishay green and halogen free.
Samples and production quantities of the new VCNL4100 are available now, with lead times of eight to twelve weeks for larger orders.
A high-speed slip ring is an electromechanical device that allows electrical current to pass between a stationary and a rotating assembly. It is typically used in applications where the speed requirement exceeds that which is achievable with a standard slip ring. High-speed slip rings are available in a variety of sizes and configurations to meet the needs of most applications. They are commonly used in military, aerospace, and medical applications where speed and reliability are critical.
The speed is required to be at least tens of thousands of revolutions per minute, the structure of the Conductive Slip Ring directly determines the contact of high speed, as well as the size of impedance. High-speed slip ring materials have high wear resistance, high life characteristics, and multi-contact contact can ensure signal transmission and power reliability, with the development of science and technology, high-speed slip rings will be more and more widely used.
If you need to transfer large amounts of data or power between two stationary objects, a high-speed conductive slip ring is what you need. Traditional slip rings only offer a few thousand revolutions per minute (RPM), which is more than enough for most applications, but can be limiting in some circumstances. Some applications, like those found in the medical or military field, require speeds of tens of thousands of RPM in order to function properly. That's where our high-speed conductive slip ring comes in. With speeds up to a certain range, it can handle even the most demanding applications.
