ELECTRONICS: C&K Components has developed a switch with life cycles to 10 million actuations. Designated the HP Series, the sealed switch features a non-contact Hall-Effect contact system and a high-energy magnet provides a linear magnetic field for the Hall device.
The Hall-effect circuit is highly sensitive and provides reliable, repetitive operation in close tolerance applications. The circuit is practically immune to environmental contaminants and can be sealed to meet IP67 specifications, making the switch ideally suited for use in harsh off-highway and industrial applications.
The HP Series switch also has the ability to have redundant, linear Hall devices. Input voltage is 5V dc, with a programmable output voltage range from 0.5 to 4.5V and one or two available outputs. Actuator travel is 0.150 inch and operating temperature ranges from -40 to 85C.
Typical pricing for the HP Series push-button switch ranges from $21 to $27 in low volumes. Lead time is from four to six 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.
