The first part of this article introduced the inductive proximity sensor. This second and final part looks at some more specifics of this sensor. Q: Are there different architectures and implementations? A: Yes, there are three basic types: 1) the magnetic elements alone are in the sensor. This separates the electronics from the sensing coils […]

What are inductive proximity sensors? Part 1
Non-contact sensing of a nearby object’s linear or rotary position in an electrically and mechanically harsh environment is a common system requirement. There are several ways to meet this objective, including sensors based on the Hall effect, the magnetorestrictive effect, and magnetic coupling. One widely used approach is inductive proximity sensing, which is effective, accurate, […]
Understanding the MIL-STD-1553B bus
by Duane Teachout, Product Manager, Cinch Connectivity Solutions Despite being over 50 years old, the MIL-STD-1553B bus is still widely used, which is probably because it is really good at its job. If you’re new to the standard, read on to learn more about its features, the terminology used and how to get the most […]
SFP, SFP-DD, QSFP, QSFP-DD & OSFP Pluggable interconnects – a 2021 update
The 21-year-old Pluggable interconnect family is now being used for new accelerator, AV, camera, machine vision, medical, memory, NVM, and proprietary interface links. New market segment expansion seems likely to continue with link shipments rising and healthy unit forecasting. New higher speed 106G and 112G per lane pluggable products will be coming out this year, […]
What are system integration issues with FPGAs?
FPGAs are complex devices and are being used in more and more systems. The complexity of FPGAs is both a strength and a weakness. It’s a strength because of the many system performance benefits and capabilities they bring for designers to leverage. It’s a weakness because of the complexities of successfully integrating high pin-count FPGAs […]
12 GHz: Will it enlarge the 5G pie?
A swath of 500 MHz that could add spectrum to 5G looks like low-hanging fruit, but it’s not without opposition. New sharing technology could solve the problem.
How does using FPGAs impact the design process?
Using field programmable gate arrays (FPGAs) can significantly increase the complexity of the design process. As seen in the previous FAQ on the application considerations when selecting FPGAs, these devices can bring improved performance to complex functions and improve overall system performance. This FAQ will consider the design process for FPGAs while the next and […]
Understanding decibels and decibel measurements
Decibels, (derived from bels, old units which, like unwieldy farads, are rarely used) are convenient and user-friendly terms for expressing the ratio between two amounts of power on a logarithmic scale or the amount of change, amplification or attenuation, over time of a single amount of power. In power and sound ratios, the factor is […]
What are the application considerations when selecting FPGAs?
Field programmable gate arrays (FPGAs) are powerful and flexible devices. They combine the performance of custom designs with reprogrammability, even after the system is in the field. As a result, FPGAs are increasingly used in various systems, from the Mars rover to fighter jets and from communications and automotive systems to a growing variety of […]
Tips on designing smart home devices – Part 2
In Part 1, we covered the design criteria to consider when creating a new smart home device and some of the smart home protocols. Here, we continue with additional device-design considerations. How can I determine which cloud platform to use? Today, multiple cloud platforms are available. It depends on which smartphone or handheld device you […]
