Balluff’s newest ceramic caps extend sensor life and minimize downtime by providing a layer of needed protection to the face of sensors in harsh conditions. The caps, which can be added easily before or after installation, protect flush mount sensors from high temperatures, weld spatter, abrasives, and impact. Often made of aluminum and magnesium/aluminum alloys, […]

Kaman Measuring launches digital differential impedance transducer
The Measuring Division of Kaman Precision Products Inc. has released a new eddy current measurement system, the Digital Differential Impedance Transducer (DDIT). The DDIT is designed to provide a digital interface for high speed eddy current measurement systems, with resolution in the micro-inch range, at bandwidths as high as 60 kilohertz (kHz). It is ideal […]
Extended range of ac powered proximity sensors
New V3 series AC powered inductive proximity sensors from AutomationDirect are available in 8, 12, 18 and 30mm sizes. Extended sensing distances for these new sensors range from 2mm shielded and 4mm unshielded for 8mm sensors to 12mm shielded and 18mm unshielded for 30mm sensors. These sensors operate on 20-250 VAC/VDC input voltage with N.O. […]
How can touch-free sensing protect public health?
Many communicable diseases, such as viruses and bacterial infections, are transmitted by direct contact with a person who has the disease or with something that person touched. Avoiding contact is an obvious way to prevent spreading diseases. Touch-free sensors allow many frequently accessed functions in restrooms, such as automatic hands-free urinal and toilet flush, hands-free […]
What types of sensors are used in robots? Part 2 of 2
In addition to the sensors identified in Part 1 of this blog, there are several others required for different types of robots. Chemical, light and color sensors enable the robot to evaluate, adjust and detect problems with its environment. For humanoid robots that can walk, run or even dance (like Dobi, made by Chinese company […]
What types of sensors are used in robots? Part 1 of 2
Fully functional human robots, such as those being developed by Boston Dynamics, need numerous sensors to simulate a variety of human and beyond human capabilities. For the human part, the sensors provide the ability to see, hear, touch and move. In general, industrial robots employ sensors for a variety of activities. Some sensors provide environmental […]
What position is this thing in?
Associated questions could include: Has it moved? In what type of motion? How close is it? While accelerometers, gyroscopes and magnetometers provide inertial measurement units (IMUs) for position sensing in smart phones and other portable products, many other sensing technologies have been used to determine position, long before the smart phone. In industrial applications, more […]
Extra-Short M12 Inductive Proximity Sensors
Carlo Gavazzi is pleased to announce an addition to the popular ICB Series family of inductive proximity sensors, with the launch of the ICB12S Extra-Short Inductive Proximity Sensors. With a thread length of only 23mm, and housing lengths as short as 25mm, these ultra-compact M12 sensors are an ideal solution where space is limited and […]
Measuring Rotor-Stator Gap
Designed as a maintenance tool for measuring rotor-stator gap in large scale power generation applications, the GMS-750RS rotor-stator gap measuring system from the Measuring Division of Kaman Precision Products, Inc., uses the company’s proven eddy current sensor technology. Incorporated into an easy to calibrate turnkey instrument, the sensing tool provides accurate and repeatable gap measurements […]
Demonstrating Sonar on a Chip
At the MEMS & Sensors Group Executive Conference in Scottsdale, AZ, Dave Horsley, Co-Founder and CTO at Chirp Microsystems demonstrates the capabilities of his company’s sonar on a chip (an ultrasound transceiver and microprocessor in a single 8-pin LGA package). The chip uses time of flight measurements for accurately detecting gesture recognition and proximity while […]
