Hamamatsu Photonics has created an x-ray image sensor for real-time non-destructive testing and digital radiography. C16401SK-51 has 1,272 x 1,104 pixels, a photo-sensitive area of 140 x 122.8mm, and uses cmos sensing with a GOS (gadolinium oxysulfide) scintillator. “This combination ensures optimal performance and reliability, even when used with x-ray tube voltages of up to 160kV, making it suitable for ...

Innodisk’s EV2U-SGR1 Camera Module revolutionizes smart parking management by offering high-quality image capturing for smart parking meters. This allows the advantage for smart parking meters to replace traditional manual enforcement methods, providing a convenient solution with features like automatic license plate recognition and real-time monitoring. This not only optimizes space usage and enhances efficiency but also relieves the burden of ...

Texas Instruments is planning a pair of precision current monitors that can measure ±50A over -4 to 110V. They are the standard INA791B (right) and the PWM residue rejecting INA790B (below). “High-precision measurements are enabled by matching the shunt resistor value and the current-sensing amplifier gain across temperature,” according to TI. “Enhanced PWM rejection reduces the effect of common-mode transients ...

A single IC can measure pH, nitrate, phosphate and potassium levels in water, according to the Fraunhofer Institute for Photonic Microsystems, which has developed a way to monolithically combine multiple ion-sensitive field-effect transistors (isfets) “Due to their resistance to breakage, isfets are already widely used in pH measurement technology, especially in food production,” according to the organisation. “Fraunhofer IPMS has ...

Standex Electronics has created a series of mini magnetic field sensing reed switches, optimised to control up to 10W, 200V or 500mA. Called MK33, they are bare glass surface-mount reed switches with a footprint only 2.2mm wide and only 2.3mm high. Construction is with a short length of 1mm diameter wire welded transversely across the ends for pre-solder-flow stability. “Mechanically, ...

Marktech had revealed the latest in its line of sensors which combine many LEDs of different wavelengths with a photodiode. MTMD142345PDT38 has five LEDs at 1.04, 1.2, 1.3, 1.46 and 1.55μm, plus an InGaAs photodiode sensitive across 600 – 1,750nm, all individually addressable and hermetically sealed into a TO-5 metal can. This short-wave infra-red (SWIR) combinations is “ideal for infrared ...

Melexis has created a magnetic sensor with functional safety for steer-by-wire systems. “For innovations like steer-by-wire systems, position sensors are a critical component that must exhibit exceptional reliability, functional safety and accuracy,” it said. “The requirements for sensors in electric vehicles are heightened, necessitating excellent EMC robustness and stray field immunity. Simultaneously, solutions must be easy to integrate.” MLX90427 as ...

Baumer has created a capacitance-based level detector for water-based liquids. “Capacitive sensing technology offers advantages, especially on applications involving aggressive liquids, food or sensitive pharmaceutical fluids used in closed containers, or where direct contact with foreign particles must be avoided,” claimed the company. “However, in some applications microfilms or residues will adhere to the inside of the walls of tanks ...

Kaman Precision Products has range of mm-scale displacement sensors that work at temperatures up to 538°C and pressures up to 5,000psi. In use, they mount into a hole in one flat surface, and measure the distance to a nearby conductive flat surface parallel to the first. There are three basic types: KD-1925 1.27mm range 0.76μm resolution 5000psi max KD-1950 3.81mm ...

The latest figures from European Components Distribution (DMASS) show a decline in Q1 of 23.3% with semiconductor revenue dropping by 26.5%. DMASS Europe’s chairman, Hermann Reiter, was keen to stress there is no cause for alarm, saying that this market consolidation was long overdue. “Everyone should have prepared to weather a few quarters of weak bookings and billings,” he said, ...
