AutomationDirect has extended
its industrial sensors to include the PEW series of stainless steel dc proximity sensors. The shielded 8 mm sensors are flush-mountable
and feature a 2 mm sensing range. Available with either M8 or M12 quick
disconnects, they are equipped with LED status indicators visible at wide
angles, and have PNP outputs. Also added are the LF40 series rectangular
inductive dc proximity sensors. Two shielded and two unshielded models are
available with 20 or 35 mm sensing ranges. The rectangular plastic PNP sensors
provide either normally-open or normally-open/normally-closed complementary
outputs. LF40 series sensor prices start at $39.
An envelope is a common packaging item, usually made of thin flat material. It is designed to contain a flat object, such as a letter or card.
Traditional envelopes are made from sheets of paper cut to one of three shapes: a rhombus, a short-arm cross, or a kite. These shapes allow for the creation of the envelope structure by folding the sheet sides around a central rectangular area. In this manner, a rectangle-faced enclosure is formed with an arrangement of four flaps on the reverse side.
A few weeks ago, Ford Motor Co. quietly announced that it was rolling out a new wrinkle to the powerful safety feature called stability control, adding even more lifesaving potential to a technology that has already been very successful.
It won't be too much longer and hardware design, as we used to know it, will be remembered alongside the slide rule and the Karnaugh map. You will need to move beyond those familiar bits and bytes into the new world of software centric design.
People who want to take advantage of solar energy in their homes no longer need to install a bolt-on solar-panel system atop their houses -- they can integrate solar-energy-harvesting shingles directing into an existing or new roof instead.
