With these kind of applications in mind, Melexis engineers designed an improved MLX91209CA high-speed linear Hall IC that achieves a response time of […]
Improvements in Hall Effect Sensors
In addition to its high current sensing products (100A – 3000A) that offer ease of integration, high accuracy and compact size, Raztec has introduced new Hall effect sensors that provide lower current measurements (measuring down in the mA range), different levels of pre-calibration and high-voltage isolation. Designed for operating temperatures from -40 to 125°C, RAZV-2 […]
OMEGA Introduces Miniature Length Sensor ZMD Series
Omega introduces its new series of miniature length sensors that are compact in size and easy to use. The ZMD series features a built-in spring- loaded torsion arm that provides a simple-to-adjust torsion load, allowing the unit to be mounted in almost any orientation, including upside-down. Using a 6″ circumference wheel, the ZMD can be […]
Two New Sensors for Hygienic and Washdown Environments
Banner Engineering announces the QM26 and the QMH26 photoelectric sensors, designed specifically for food and beverage and pharmaceutical industries. Influenced by the 2011 Food Safety Modernization Act (FSMA), the European Hygienic Engineering and Design Group (EHEDG) and food safety initiatives among private businesses, Banner wanted to ensure the sensors provided reliable performance in manufacturing and […]
TURCK’s High-Speed Inductive Linear Position Sensor
TURCK introduced a further developed LI inductive linear position sensor. A new electronics architecture increases the effective output rate of the sensor from 1 to 5 kHz. In conjunction with the short signal run time (130 µs) and the highly resolved SSi output, the inductive linear position sensors can achieve the performance of potentiometers but […]
Digital Output DC Current Sensor Avoids Sampling and A/D Converter Circuitry
Typical current sensing techniques that use a Hall Effect sensor or a resistive shunt deliver an analog output that requires additional circuitry for use in digital control circuits. Micro Oscillator Inc. has introduced an isolated high-side DC current sensor that provides a uni-directional current sensing system with a frequency output. The pulsed output of the […]
Split-Core Coils Sensor Suitable For Use In Class 1 Power Devices
LEM has introduced the first of its AC current sensor families based on Perfect Loop Technology. After calibration, the new RT series achieves absolute accuracy of better than 0,65% – including position error – making them the first split-core Rogowski coils to be suitable for use in Class 1 power devices. An imperfect coil structure […]
Mini Voltage/Current Detection Optocouplers
Avago Technologies announced two new miniature voltage/current threshold detection optocouplers for use in a wide range of industrial control applications. The ACPL-K370/K376 optocouplers are designed to detect AC/DC sources and convert the voltage to a logic interface across an optical coupling barrier to provide safe isolation in electronically noisy environments found in industrial applications. These […]
