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.
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.
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.
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.
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
The company says it anticipates high-definition video for home security and other uses will be the next mature technology integrated into the IoT domain, hence the introduction of its MatrixCam devkit.
Siemens and Georgia Institute of Technology are partnering to address limitations in the current additive manufacturing design-to-production chain in an applied research project as part of the federally backed America Makes program.
Most of the new 3D printers and 3D printing technologies in this crop are breaking some boundaries, whether it's build volume-per-dollar ratios, multimaterials printing techniques, or new materials types.
