C&K Components has upgraded its KMT0 Series of
ultra-miniature tactile switches to provide IP68-rated sealing. The
industry's only ultra-miniature tactile switch with an IP68-rated
sealing, the KMT0 Series is completely sealed and stays fully functional
under water for a minimum of 5 hours at a depth of 2 meters.
In addition, the KMT0 Series is fully resistant to the most stringent
conformal polymer coatings and features a lifespan of more than 300,000
electrical and mechanical cycles. With a footprint of only 3.0x2.6mm
with a height of 0.63mm or 0.65mm, the RoHS-compliant halogen-free
switches are suitable for handheld and portable electronic device
applications. All devices of the KTM0 Series feature a maximum power
rating of 0.5VA and a minimum/maximum voltage of 20mV to 32Vdc with a
minimum/maximum current rating of 1mA to 50mA. The operating temperature
ranges from -40 to +85°C.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
