Novotechnik, U.S. introduces the MC-1 2800 44-Turn magnetic encoder with IO-Link output interface. Patented non-volatile technology retains turn count even when power is lost and reports correct count when power is restored. Key specifications for the MC-1 2800 include a measuring range of 15,840° (44 turns), and measured variable information of angle, turns, speed, and […]

What are magnetic rotary encoders?
Part 1 of this FAQ looked at the optical rotary encoder, a low-cost, high-resolution, easy-to-use sensor for indicating incremental shaft position (although it can be “upgraded” to indicate absolute position as well). Q: What is the basic principle of the magnetic encoder? A: The magnetic encoder uses a rotating gear made of ferrous metal, and […]
Magnetic guide sensor boosts robotic path-tracking accuracy with 1mm precision”
Naviq is introducing the MTS160, a state-of-the-art magnetic guide sensor for mobile robots, featuring patented angle measurement capabilities with 1-degree precision and position accuracy within 1mm. This unique dual functionality provides exceptional orientation and positioning precision, significantly improving the navigation capabilities of mobile robotic systems. Unlike traditional magnetic line-following sensors that only detect position along […]

Magnetometer features field shock recovery
Bosch Sensortec announces its next-generation magnetometer, the BMM350, which provides excellent performance with low current consumption to extend battery life. It enables a wide range of new use cases, including detecting head orientation for 3D audio, and pixel latency reduction in AR/VR to improve the user experience and avoid motion sickness. In indoor navigation, the […]
Magnetic sensors optimized for ADAS applications
Allegro MicroSystems, Inc. announced the launch of its A33110 and A33115 magnetic position sensors at the Sensors Converge Conference in San Jose, CA. Designed for advanced driver assistance systems (ADAS) applications that require high levels of accuracy and heterogeneous signal redundancy, Allegro’s newest sensors combine the company’s vertical Hall technology (VHT) with cutting-edge tunneling magnetoresistance (TMR) technology in […]
Teardown: Inside an industrial absolute encoder
If you go to the Wikipedia page on absolute encoders, you’ll find descriptions of these devices mentioning multiple code rings, glass or plastic discs, and configurations of sliding contacts arranged so each contact wipes against a metal disc at a different distance from a turning shaft. Actually, you’d be hard pressed to find any of […]
How can you see through walls?
It depends on what you want to “see” and how much you want to pay. To locate a stud, the old school technique of tapping a tool on the wall for acoustic differences used hearing rather than sight and it was free. Initially, battery-operated stud finders used magnets to find screws and nails and provided […]
How to optimize building and home automation designs to be more energy-efficient
By Brian Dempsey, system design engineer, Texas Instruments The numbers are a wake-up call: According to the United Nations, the buildings and construction sector accounted for 36% of the world’s energy consumption in 2018, contributing to a worrisome carbon footprint. And those percentages continue to grow. As a result, the race is on. Industrial design […]
