With 11 Gauss max sensitivity, Honeywell’s Standard Power Series Sensor ICs allow larger air gaps between the sensor IC and the magnet or decreasing the total design cost by using smaller, less expensive magnets. The magnetoresistive (MR) sensors have a solid-state, non-contact, no-glass design that makes them durable and reliable and operate over a temperature […]

Universal Input Reference Design Provides Accuracy and Flexibility for Industrial Sensors
Industrial automation engineers can now achieve highly accurate measurements for their system designs with the MAXREFDES67# analog front end (AFE) universal input Micro PLC reference design from Maxim Integrated Products, Inc. (NASDAQ: MXIM). As high-resolution systems move to higher bit counts, they become more sensitive to noise, making such systems difficult to build and maintain […]
Tactical-Grade MEMS Inertial Sensor
With the 3DM-GQ4-4, LORD MicroStrain integrates a triaxial accelerometer, gyroscope, magnetometer, temperature sensors, and a pressure altimeter into a tactical-grade all-in-one navigation solution with integrated GNSS. With these sensors, the Inertial Measurement Unit (IMU) can directly measure acceleration, angular rate, and atmospheric pressure. When processed through a sophisticated estimation filter algorithm, the IMU achieves high […]
280 MPH Electric Car Employs Smart Position Sensors
What does it take to create an electric vehicle that would be competitive at the Le Mans 24-hour race? Finland-based Toroidion Oy engineers are building an electric concept 1MW powered supercar that is expected to reach 280 mph. To achieve the performance they want, precise sensors are on their bill of materials. To get that […]
Measure Hydraulic Valve Position without Pressure-Induced Variations
Based on the high pressure ranges at which they operate, measuring the position of the hydraulic valve can be challenging. A properly designed linear variable differential transformer (LVDT) sensor can solve this problem. That is exactly what German manufacturer INELTA did. Mounted inside the existing hydraulic valve assemblies, the LVDT’s electromagnetic coupling measures the core […]
Round, elliptical and rectangular trackpad modules
Azoteq, a manufacturer in capacitive proximity and touch solutions, announced the release to market of eight ready to use trackpad modules. The trackpad modules come in a range of shapes and sizes to enable rapid integration into existing or new products. The round and elliptical trackpads are aimed at Bluetooth headset applications. Swipe and tap gestures are […]
Inductive Linear Position Sensors Address Existing Hydraulic Cylinder Designs
The MHP-7 in-cylinder position sensor product line from Alliance Sensors Group, a div of H.G. Schaevitz LLC, were designed for installation into the rear endcap of hydraulic cylinders for operation at pressures up to 5000psig. Available in a compact 1-inch hex aluminum or stainless steel housing and ranges from 25 to 600 mm (1 to […]
MLU Technology for Sensor Products
In this Frank Talk about Sensors, Randy Frank talks to Dr. Lj Ristic from Crocus Technology about the use of the Magnetic Logic Unit (MLU) technology for Sensors. For more information about Crocus Technology’s use of Magnetic Logic Unit technology, click here.
Fiber Optic Sensing Improves Medical Measurements and More
Unlike strain gages, thermocouples, liquid level and other sensors that only measure critical points, distributed fiber optic sensing (FOS) can provide a profile between the critical points. Sensuron’s FOS systems take advantage of this capability in 200 µm diameter, 3-dimensional positioning, pressure and temperature sensors. In a surgical instrument, a thin, flexible, high-density fiber optic […]
Integrated Fluxgate Sensor Operates on 3.3V
Among other integrated capabilities, Texas Instruments DRV421 magnetic sensing IC operates from 3.3V supply to simplify interfacing to ADCs on low-power microcontrollers. Target applications include magnetic closed-loop current sensing in motor controls, renewable energy, battery chargers and power monitoring. The 4-mm-by-4-mm quad flat no-lead (QFN) packaged IC contains a fully integrated fluxgate sensor and compensation […]
