MATERIALS:PEM® self-clinching concealed-head studs and standoffs install permanently in steel or aluminum sheets as thin as .062 ionch/1.6mm to provide strong and reusable threads for mating hardware in a wide range of thin-metal assembly applications. Their concealed-head feature contributes particular design benefits by allowing the side of the sheet opposite installation to remain smooth and untouched. This feature additionally serves to satisfy applications where the sheet must remain completely sealed from air, liquid, dust, gases, or other potentially infiltrating elements.The aluminum or stainless steel studs are available in thread sizes #4-40 through #10-32 and M3 through M5 and in lengths from .250 through 1 inch and 6 through 25 mm. Stainless steel standoffs are offered in thread sizes #4-40 through 1/4-20 and M3 through M6 and in lengths from .187 through 1 inch and 4 through 25 mm.
Sheet preparation for their installation requires only a blind milled hole to the recommended minimum depth. Using a PEMSERTER® or other standard press, installation is accomplished by placing the fastener in the hole and applying sufficient squeezing force. The fastener head then locks securely in the sheet and can handle substantial loads.
These fasteners are RoHS-compliant and some stud types meet NASM63540 specifications. Detailed specifications (Bulletin CH) and free part drawings (PEM CAD Library) can be accessed at www.pemnet.com.
Truchard will be presented the award at the 2014 Golden Mousetrap Awards ceremony during the co-located events Pacific Design & Manufacturing, MD&M West, WestPack, PLASTEC West, Electronics West, ATX West, and AeroCon.
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.
