High Performance Image Sensors at the Front-end of a Growing Security Market
As we all want to live, work and travel in the utmost safety, the security market has seen rapid growth and advancement in recent years. Electronics semiconductor technology is synonymous with the sector and a key enabler for many systems in place today.
Surveillance video capture and processing in order to provide security has become a huge growth market in applications such as offices and other workplaces, plus stores, shopping malls and all kinds of general public spaces. The demand for, and value of, high quality, better performing and robust imaging solutions is very strong with the obvious benefits of easier, clearer recognition of activities, locations or people being observed.
Remote video surveillance can alleviate the need for manned security, mitigates for human attention span errors and continuity issues, and can enable those tasked with providing security to provide coverage of large areas around the clock.
ISC West – the largest tradeshow in the U.S. dedicated to the security industry - takes place in Las Vegas this month. Attended by almost 30,000 security sector professionals, the event provides a focal point and place where awareness is enhanced and the benefits of the very latest technology can be shared. The collaborative, learning environment of a tradeshow supports the ongoing design of the solutions that are more advanced and beneficial to the growing number and diversity of end applications.
ON Semiconductor is at the forefront of imaging technology for security and surveillance, and the launch of its latest digital image sensor for the sector will be synchronized with ISC West. The AR0521 offers class-leading low light performance – very often a key requirement for security applications, and video performance at 5 mega pixels 60 frames per second with a 1440p mode for 16:9 video. This, when combined with a host of other processing functions and features, delivers the extraordinarily clear and sharp images, even in poor light conditions, as are increasingly demanded by customers throughout the sector.
The AR0521’s -30 to +85°C operating temperature range means users don’t need to worry about compromised performance in the environments in which it is used either indoors or outdoors. It is also designed to work effectively in any of the latest commercial ‘observation formats’ including birds-eye, long -range and speed dome systems which are widely used in retail, office and other public buildings and areas. Each of these has some unique and several overlapping requirements that can include the need for image stitching signal processing, high frame rates for high resolution, advanced line synchronization for multi-camera systems and high dynamic range.
Video surveillance is here and here to stay, and in many aspects of our day-to-day personal and working lives it is there in the background for our ultimate benefit and safety. Historically the quality, functionality and connectivity might not have been exactly what was required to make it truly effective. But now with ever more sophisticated and robust electronics supporting the front-end image sensing needs, system makers have access to just what they need.

AVX Releases New Vertical Poke-Home Connector Carefully Tooled to Compete Against Hand Soldering in 18AWG Applications
FOUNTAIN INN, S.C. (January 17, 2017) - AVX Corporation, a leading manufacturer and supplier of passive components and interconnect solutions, has released the first vertical connector capable of successfully bridging the gap between inexpensive, but wildly inconsistent hand soldering processes and expensive, but exceedingly reliable two-piece connector systems in high volume, 18AWG applications with perpendicular terminations and limited board space, including: power supplies, LED drivers, and industrial and motor controls. Carefully tooled to effectively compete against hand soldering processes, which are all but completely devoid of materials costs, the new 58-9296 Series single position, vertical poke-home connectors finally provide design engineers with a compact, cost-effective, and electrically and mechanically reliable alternative to hand soldering. Featuring a unique, stamped and formed phosphor bronze box contact that maximizes both board attachment and wire capturing strength, the new vertical poke-home connectors are 23% smaller than existing vertical connector solutions, allowing them to fit into the extremely tight spaces between larger, densely populated plated through hole (PTH) components, and have tight tolerances in critical areas to minimize the potential for ingress resulting from the secondary potting or epoxy encapsulation processes commonly employed to protect industrial electronics from water and other harsh environmental hazards.
"Our new 58-9296 Series vertical poke-home connectors deliver reliable, repeatable solutions for a wide variety of 18AWG applications with vertical terminations and limited board space at a price/performance ratio that any design engineer who's open to examining their true applied costs - which include quality, process issues, and throughput - will find attractive," said Tom Anderson, connector product manager, AVX. "It was challenging to strike the appropriate balance between cheap, but inconsistent hand soldering processes and consistent, but expensive two-piece connector solutions, but this new series successfully delivers electrical and mechanical reliability in a minimal x/y footprint at a cost that will finally allow EEs to prioritize performance while simultaneously minimizing costs."
The series' robust, single beam, phosphor bronze box contact securely captures and retains solid, 18AWG wires; exhibits excellent spring performance, high fatigue, and corrosion resistance; and reliably withstands the mechanical and environmental stresses associated with large, 18AWG wires in industrial applications, including: industrial machine controls, power supplies, motors, drives, solenoids, sensors, fans, and pumps; commercial building controls and security and fire sensors; smart grid meters, breakers, and panels; and SSL/LED drivers, fixtures, signage, and streetlights. Rated for 8A, 600VAC, and operating temperatures spanning -40°C to +130°C, the new 58-9296 Series connectors also feature lead-free, tin plating that enhances corrosion resistance and contact strength, dual solder tabs that effectively anchor the connector onto PCBs, and, instead of costly Kapton® tape, an integral molded flange with a generous vacuum pick-up point for automated SMT placement. The RoHS compliant series is also rated for three-cycle durability, allowing for up to two wire replacements over the product's lifetime, and is packaged on tape and reel.
