Tips for Selecting or Designing a Membrane Switch

Membrane switches are known for standing up to tough environmental conditions. Flexible and durable, the membrane switch can be customized with embossing, backlighting, sealing, and electrostatic discharge (ESD) shielding. Membrane switches can be made with either tactile or non-tactile feedback and they can be integrated with LEDs and other components. To get the switch that works for your application, follow these simple guidelines.

PCIe RAID Controller Cards

StarTech.com (Lockbourne, OH) has released two new PCI Express RAID Controller Cards (SKUs: PEXSAT34RH, PEXSAT34SFF). The new PCIe RAID cards feature Marvell™ HyperDuo SSD Auto-Tiering Technology, an embedded technology for 6Gbps SATA controllers that allows users to combine SATA SSD and HDD drives into a single volume (up to 3 SSD + 1 HDD), while built-in HyperDuo technology discreetly identifies and moves frequently accessed files to the faster SSD drive(s). While providing the improved speed and data throughput (up to 80% SSD performance), the cards still enable all data to be safely stored on a larger capacity HDD. The HyperDuo feature can be configured either at the boot level (no software required) or at the OS level through an intuitive administration GUI console in Windows.

Microcontrollers

LAPIS Semiconductor (San Jose, CA), a ROHM Group Company, recently introduced the ML610Q100 series of low-cost, low-power microcontrollers. The Mini LP Micros’ peripherals around the processing core and non-volatile memory and RAM include: GPIO, PWMs, counter/timer blocks, ADCs and comparators. The devices exhibit very low power consumption in both sleep (1uA typical) and operating modes (3.7mA typical), while executing one instruction per clock cycle at up to 8 MHz clock rates. The microcontrollers are unique in having their timing reference circuit completely integrated within the devices, meaning no external crystal or any other component is required. Some of the devices in the Mini LP Micro series have internal writable Flash RAM, which eliminates the need for external EEPROM for data storage. Their wide supply voltage range (2.7V dc to 5.5Vdc) and temperature range (-40°C to 85°C) allow the Mini LP Micros to be used in battery-powered and energy-harvesting applications located in harsh environments.

Multi-Phase Power Analyzer

Tektronix, Inc. (Beaverton, OR) recently announced its new precision multi- phase power analyzer. Featuring the industry’s first Spiral Shunt™ design (patent application submitted), the Tektronix PA4000 power analyzer gives power electronics engineers stable, precise current measurements even on highly distorted power waveforms common in many applications. The PA4000 uses two Spiral Shunts on each channel – one for current measurements up to 1 A, for precise low-current measurements, and one for current measurements up to 30A, for higher-current measurements. This state-of-the-art shunt design is then combined with unique high-speed digital signal processing algorithms, allowing the PA4000 to track power cycles accurately, even in the presence of transients and noise.

SMT Top Actuated Switch

C&K Components (Newton, MA) has developed the new PTS 530 Series ultra-low- profile top actuated SMT switch. Utilizing C&K’s unique symbol line identification system, design engineers can quickly and easily identify actuation force ratings. The marking system defines the model number and actuation force on the switch itself, which eliminates the need for designers to rely on confusing schematics. The PTS 530 Series SMT switch is only 4.5mm x 4.5mm with a 0.55mm thickness (0.65 mm for high force versions) and features a lifespan of up to 1,000,000 operations. The momentary action, top actuated SMT switch features a gullwing or J-type terminal and can be soldered via infrared reflow in accordance with the IEC61760-1 standard. The PTS 530 Series switches are available in six different varieties, dependent on actuation force. The PTS 530 Series SMT switch has a maximum voltage of 12VDC. The operating temperature range is -40°C to +85°C.

Small Form Factor Computers Go Ultra-low Power

Agrowing number of mobile, space constrained or harsh environment applications are being designed for the military, industrial automation/HMI, digital signage and medical markets that are driving the need for ever-lower power consumption. These embedded systems have been underserved by existing SFF platforms that have not been able to offer ultra-low power operation, many times below 3 Watts, in a slim profile design. OEM developers have also been challenged to find computing platforms that deliver a flexible and scalable solution in terms of performance and rugged reliability with state-of-the-art interface and graphics support that mimics the same functionality as today’s smart consumer devices.
