Tool Identification in Metalworking

Guest contributor: Martin Kurzblog, Fan of Industrial Automation With the start of industry 3.0 (the computer based automation of production) the users of machine tools began to avoid routine work like manually entering tool data into the HMI.  Computerized Numerical Controlled CNC machine tools gained more and more market share in metalworking applications.  These machines are quite often equipped with

How hot is hot? The basics of Infrared Temperature Sensors

Guest Contributor:  Jack Moermond, Balluff Detecting hot objects in industrial applications can be quite challenging. There are a number of technologies available for these applications depending on the temperatures involved and the accuracy required. In this blog we are going to focus on infrared temperature sensors. Every object with a temperature above absolute zero (-273.15°C or

IO-Link Hydraulic Cylinder Position Feedback

Guest contributor: Scott Rosenberger, Balluff Ready for a better mousetrap?  Read on….. Some time ago on Sensortech, we discussed considerations for choosing the right in-cylinder position feedback sensor.  In that article, we said: “…….Analog 0-10 Vdc or 4-20 mA interfaces probably make up 70-80% of all in-cylinder feedback in use…..” And while that 70-80% analog figure

Basic Color Sensor Overview

Guest contributor:  Jack Moermond, Balluff In the past, color sensors emitted light using red, green and blue LEDs. The sensors were then able to distinguish colors using the RGB components of the reflected light back to the sensor’s receiver. As technology has progressed true color sensors have been developed that not only can compare colors

3 Smart Applications for Process Visualization

Guest contributor: Shishir Rege, Balluff Stack lights used in today’s industrial automation haven’t changed their form or purpose for ages: to visually show the state (not status) of the work-cell. Since the introduction of SmartLight, I have seen customers give new meaning to the term “process visualization”. Almost every month I hear about yet another

Reliable Part Exit/Part-Out Detection

Guest contributor: Dave Bird, Balluff Walk into any die shop in the US and nine out of ten times, we discover diffuse reflective sensors being used to detect a large part or a small part exiting a die. Many people have success using this methodology, but lubrication-covered tumbling parts can create challenges for diffuse-reflective photoelectric

3 Tips for Reducing Downtime

Guest contributor:  Janet Czubek, Balluff:  Whether it’s through preventative maintenance or during planned machine downtime, reducing downtime is a common goal for manufacturers. Difficult environments create challenges for not just machines, but also the components like sensors or cables. Below are three tips to help protect these components and reduce your downtime. Cables don’t last forever.

Demand the best from your RFID partner

Guest contributor, Wolfgang Kratzenberg, Balluff That seems like a no-brainer statement, but often I find myself talking to customers who are frustrated with their current vendor for a myriad of reasons. An RFID project can require a pretty decent chunk of capital investment so when something doesn’t go as planned people start looking for answers immediately. This

Three Things to Know About IO-Link

Guest contributor: Pat Millott, Balluff IO-Link has become synonymous with the term “distributed modular I/O”. We know it is universal, smart, and easy, but what exactly is IO-Link? In a nutshell, by utilizing a standard sensor cable, the IO-Link slave device speaks point to point with an IO-Link master. The IO-Link master then combines the

A Simple Out Feed Solution for Progressive Stamping

Guest contributor: Dave Bird, Balluff Applications where sensor contact is unavoidable are some of the most challenging to solve. Metal forming processes involving over travel can also damage or even destroy a sensor causing failure and expensive unplanned downtime. Manufacturers often try to remedy this with in-house manufactured spring loaded out-feed mechanisms but those are
