We have released slightly updated (irs05b) versions of our 38Â kHz IR proximity sensors and discontinued the previous (irs05a) versions. The main changes are to the locations of the IR emitter and receiver, which have been moved away from the edge of the board. This results in better shielding from the PCB itself, which improves performance. Also, the front edge is now routed rather than scored to provide a cleaner edge that also slightly improves the sensor performance and consistency.
Like the originals, these new sensors are available in high-brightness and low-brightness versions with typical sensing ranges up to around 24″ (60 cm) and 12″ (30 cm), respectively. The new versions have the same dimensions and pinouts as the originals, so they can be used as drop-in replacements for any applications that are not dependent on the original component locations.

Lithium-ion Battery Market - Shadowing the Growth of EVs
The lithium-ion battery market will grow over 2x between 2017 and 2027 – where will this spurt in growth come from? Unsurprisingly, consumer electronics will be at the forefront; however, it will witness massive uptake by the automobile industry that will catalyze revenue streams. As EV penetration grows rapidly, and the automotive industry looks to reduce its dependence on fossils, lithium-ion battery manufacturers will unlock access to opportunities that were unthinkable of a decade ago.
Growth will also be complemented by the growing focus on renewables. As government and private initiatives on harnessing solar and wind energy gain traction, the lithium-ion industry will play a central role. However, amidst the euphoria in the industry, the traditional challenges associated with supply/demand are also likely to crop up. Also, while a majority of the lithium-ion batteries manufactured currently satisfy the 'cycle stability' parameter, creating next-gen batteries that do not falter in terms of 'overall age' remains a challenge. Overall, these are exciting times to be in the lithium-ion battery landscape, as the highly-touted EV revolution grows stronger by the day.
