ELECTRONICS: C&K Components developed a new series of through-hole subminiature detect switches. Available with pretravel and overtravel, the KM1202 features a highly reliable contact design with a minimum electrical life of 10,000 actuations at full load.
The KM Series detect switches are available with gold- or silver-plated contacts. Maximum contact rating for the gold-plated switches is 0.4A at 20V ac or dc, while the silver-plated devices feature a contact rating of 0.25A at 125V ac or dc. Maximum contact resistance is 30mΩ at 2 to 4V dc for both the silver and gold-plated contacts, and minimum dielectric strength is 1,000Vrms. Operating temperature ranges from -30C and +85C. The RoHS compliant and compatible KM Series detect switches feature a pretravel measurement of 4.06mm. Total travel is 5.84mm.
Typical pricing for the KM Series subminiature detect switches ranges from $1.50 to $2.20 each in quantities of 2,500 pieces. Lead time is from 5 to 7 weeks.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
