Product Information Dear Reader, Happy February to our readers.  If you're like most of the rest of the world you've been enjoying the winter Olympics.  It's been a thrill to see some of the world's best athletes doing what they do best.  The level of performance is extraordinary.  We may not be Olympic athletes, but seeing the results of this dedication and hard work is inspiring to all of us at BEI who work hard every day to give you our best.  See you on the podium! Be a Smarty As you can imagine, we are constantly adding new readers to our newsletter.  At the same time we realize that many of our regular readers don't use or specify encoders for every project; so a little refresher would be nice from time to time.    What better way to serve both groups than to introduce (or re-introduce) you to encoders with our ever popular "Encoders for Dummies" reference guide.   Yes, it's true.  When it comes to encoders - we wrote the book and you can have your own copy just by clicking on the picture below.  Don't be a Dummy - be a Smarty and order your copy today.  No professional library should be without one! Dig This "Basically, I have been compelled by curiosity."    "I had never passed a single school exam, and clearly never would."   "I'd rather be in a tent than in a house."    This is rather an odd collection of comments until you understand who said them. The picture on the left portrays Mary Leakey one of the foremost Archaeologists of the 20th century.  She is known for her work in the Olduvai desert in Africa where she expanded our understanding of the evolution of Hominids starting over 2 million years ago.   Though her childhood was unspectacular she was exposed at an early age to archeological excavations in the Dordogne region of France.  Young Mary was so enthralled it became her lifelong ambition to work as an archeologist.    Despite an unsuccessful attempt to educate her at a Catholic convent (she was expelled twice) she eventually managed to get an education and employment as a personal assistant to Dorothy Liddell during field excavations.  Mary's illustrations eventually were the springboard for her career; leading to her seminal work in Africa and marriage to Dr. Louis Leakey.   To read more about this remarkable woman.  Just click her picture and you can read a more complete biography.     Can You Solve This? You have to hand it to our customers because they sure do make life interesting.  We were working with a customer that needed to measure the rotation of a shaft on the input stage of a gear reduction.  No problem.  There would be some minor vibration.  No problem.  Maybe some high ambient temperatures.  No problem.  There wasn't much room for the installation.  No problem.  Oh and by the way, the gear shaft was inside the gear box and the encoder would be constantly bathed in gear oil.  Problem? Answer:  First of all we specified the ES25 with it's IP67 rating and magnetic coupling.  However, gear oils run the gamut of formulations and the major issue with them is that they can react with the seals in encoders.  We obtained a sample of the gear oil and the specifications.  We tested to make sure they we had a good match between the seal material and the oil and we were good to go.   To check out the ES25 specification sheet, just click the picture.       Runaway Runways Most designers welcome a real challenge, but few have had to step up like the one's who designed this collection of airport landing strips.  Middle of the ocean?  No problem.  Can't dig up the golf course?  We'll build around it. Share the runway with street traffic?  We'll put in a crossing gate and a stoplight.  Bring it on.   If you want to get the inside scoop on 18 of the world's wackiest airport landing strips, then click on the image above and check them out. Hope you found this month's newsletter informative and enjoyable.  Let us know if there is something we can do to help. Give us a call or send an email.
