Extra-flat RAFIX 30 FS+ for high-level design requirements
RAFI’s new RAFIX 30 FS+ series control components offer all the benefits as extra-flat lenses and an even lower overall height: the new series pushbuttons rise only 3.45 mm above the front plate.
Pushbuttons for individual labeling
FLEXLAB pushbuttons from the RAFIX 22 FS series by RAFI can be individually labeled and allow mechanical engineers to reduce time for planning or making customization to operating devices. Thanks to the option of subsequently labeling the FLEXLAB pushbutton, function assignments relevant to the target application need not be taken into consideration too early, but can be carried out at a convenient later time – including by the end customer.
Directionality of microphones
The pick-up efficiency of a microphone may vary depending on the direction from which the sound comes. This characteristic can be an unavoidable consequence of the design of the microphone or a conscious design to obtain properties for specific purposes. Some microphones also have variable characteristics. This is usually illustrated graphically in diagrams showing the characteristics. In this case the microphone is located in the centre with its front directed upwards in the diagram.
Modern magnets and corrosion
Neodymium magnets, or rather NdFeB, are products produced by powder metallurgy and based on neodymium, iron and boron, which makes magnets that are impressive in relation to their strong magnetic field. They are actually the strongest permanent magnets that can be produced today.
What is not as well known is that neodymium magnets are susceptible to corrosion in their raw state. When the magnets are exposed to humidity they can corrode, which can destroy the magnet if the magnets are not treated correctly from the outset. The magnets can be surface treated to prevent corrosion.
Five technologies for obtaining linear motion with electric motors
Many applications for electric motors involve the conversion of a rotary motion to a linear motion, e.g. in actuators, XY tables, zoom or focus in optical applications etc.
This can be done in many different ways, with different advantages and disadvantages, which are suitable for different applications. In this article we look at some of the common methods of producing linear motion with electric motors.
