NKK Switches
has expanded its FR Series of 10mm surface mount DIP rotary switches
to include a shaft-actuated option. Previous versions of SMT FR Series devices
were only available with screwdriver actuation. The FR02 shaft actuated version
enables hand actuation, while still retaining the ability to be adjusted with a
flat tipped screwdriver. With a height of 3.8 mm the FR Series devices have a
low profile and allow close stacking of PC boards.
The
detent mechanism of the FR Series gives a positive action providing accurate
switch setting. Actuators are fully rotational and can be operated either
clockwise or counterclockwise. Ten-position decimal and 16-position hexadecimal
configurations are available in real or complement codes. Legends with an arrow
indicate position for trouble-free code setting whether shaft or screwdriver
actuated. Color-keyed actuators identify codes.
The cam
activated movable contact and gold contacts ensure contact reliability and
continuity. The electrical rating is 100mA @ 5V dc while switching, and 100mA @
50V dc when not switching. The operating temperature range is -25 to 85C.
These
devices are straight mount and feature gull wing terminals. Gull-winged
terminals deliver mechanical stability during soldering and simplify solder
joint inspection. The coplanarity tolerance zone is 0.15 mm maximum, the
allowable distance between all considered surfaces in two parallel planes.
FR02
devices meet the RoHs directive restricting the use of hazardous substances and
the heat resistant resin materials are UL94V-0 and allow for infrared
convection reflow soldering. Packaging for FR02 switches includes a tape-reel
of 200 pieces for shaft-actuated models or 500 pieces per tape-reel for
screwdriver actuated models. Stick tube packaging of 50 pieces is also
available.
As energy efficiency becomes more and more a concern for makers of electronics devices, researchers are coming up with new ways to harvest energy from sound vibration, footsteps, and even electromagnetic fields in the air.
The government wants to study your brain, and DARPA wants to use similar information to give robots true autonomy beyond any artificial intelligence developed to date. Sound like science fiction? It's not.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
