Monitoring vital signs such as pulse or oxygen saturation in the blood via smartphones and smartwatches has been available for several years. The corresponding UV channel of the ambient light sensor TSL2585 from ams OSRAM detects the amount of UV-A radiation in natural sunlight. This enables the user to be warned of excessive UV-A radiation. Thanks […]
Cryogenic test and eval kit accommodates oxygen-based FPA
Sunseeker Engineering has introduced a cryogenic test and evaluation kit for the Oxygen RD0092 digital readout IC (DROIC) that enables focal plane array (FPA) developers to expedite their FPA development and evaluation process. “The purpose of the kit is to bring-up and optimize the performance of an Oxygen-based infrared image sensor as efficiently as possible […]
Right-angle edge surface mount tact switch provides life expectancy of 600K cycles
The TL4115 tact series is a right-angle edge surface mount design and provides life expectancy of 600,000 cycle in a 4.50mm x 2.20mm x 2.60mm footprint. This switch series features a soft round actuator and provides 160gf or 220gf operating force options.

Multi-range pressure sensor for sleep apnea devices
Superior Sensor Technology introduced a new dual low-pressure sensor product series for continuous PAP (CPAP), bi-level PAP (BiPAP) and automatic PAP (APAP) products used for sleep apnea and other breathing sleep disorders. The CP Series is the industry’s first dual, multi-range pressure sensor that integrates a differential pressure sensor and a gage pressure sensor into one solution. […]
Principles, selection and design with piezoelectric actuators
By Patrik Kalbermatten, Senior Manager – Distribution Promotion Product Management Magnetic, Sensor & Actuator at KEMET Electronics Corporation a YAGEO company Piezoelectric actuators that exploit the inverse piezoelectric effect to produce a displacement in response to an applied voltage can offer an alternative to familiar electromagnetic devices such as motors and solenoids. They offer advantages […]
Switches: The complete guide
From DIP, rotary DIP, and slide switches to tactile, rocker, push button, and toggle switches, there is a nearly limitless range of mechanical switches differing in size, shape, interfaces, and features. Although a relatively basic component in electronic design, each switch type has its benefits, drawbacks, and ideal use cases. Because all switches serve a […]
Differential pressure transmitters are quickly configurable, require no calibration
Superior Sensor Technology today announced the HS Series, an advanced family of differential pressure transmitter (DPT) subsystems that offer engineers a flexible, accurate and easily configurable DPT design solution for HVAC and industrial air handling systems. The HS Series is a DPT subsystem which includes the already popular performance features of the HV Series with additional […]
Analyzing different proximity sensor technologies
Utilized as a no-touch method to provide either precise distance measurement to an object or simple “there/not there” logic, proximity sensors span a wide range of technologies, each offering their own set of operating principles, advantages, and drawbacks. Some of the most commonly found technologies in portable or small embedded systems include ultrasonic, photoelectric, laser […]
Thin film haptic actuators create high-fidelity in a localized way
While piezoelectric haptic solutions are found in many applications, they are often large and heavy, thus shaking the entire device. KEMET’s new piezoelectric polymer film haptic actuators are thin (150 µm), flexible and conformable devices made from a proprietary, patent-protected paper-thin material, an electro-active polymer film, that enables piezoelectric effects to mimic the sense of […]
An overview of absolute encoder communication protocols
Depending on the application, a controller or variable-speed electric-motor drive may need to measure any combination of rotor speed, position, and direction. Absolute encoders are a popular motion control choice with their ability to determine rotor position immediately at power on, while also being able to keep track of position during sudden power losses. With […]
