Implement Hassle Free Tool Changes

The Problem

From conversations with many of our customers, I have found that there are two key problems encountered when working with tool change-outs:

  1. Tool Identification:  “How do I know I have the right tool in there for the right job at the right time?”
  2. Cables & Connectors:  “How do I remember every time to disconnect them before the tooling is removed?  We spend thousands each year repairing dies with the cordsets torn out.”

Flush or Non-Flush – What’s the Difference?

In a previous blog Flush or Non-Flush, Looks Can Be Deceiving, Jeff mentions the two common housing designs of inductive sensors, flush and non-flush. So what does this mean to you when you are applying an inductive or even a capacitive sensor?

Flush-style sensors actually have a shield that restricts the magnetic field so that it only radiates out of the face of the sensor. Flush-style, or shielded sensors, can be mounted flush in a metal bracket or even in your machine without the metal causing the sensor to false trigger. When mounting two shielded inductive proximity sensors next to each other, you should typically leave one diameter of the sensor between adjacent sensors. The shielded-style of sensor will typically have approximately one-half of the sensing distance that a non-shielded version will have. For example, a 12mm shielded inductive sensor will have a sensing distance 2mm whereas a non-shielded version will have a sensing distance of 4mm. Although shielded style sensors have a shorter sensing range they can be buried in a machine or a bracket that will offer protection against damage.

Visit Automation Tradeshows for Free!

I am experiencing the future of tradeshows; a networking & educational conference without the travel, the expense, and the suit!  I can sit at my desk and make contact with future vendors and customers.  The online database GlobalSpec hosts multiple times per year industry specific virtual tradeshow events.  There are presentations and exhibitors.  A place to sit and drink virtual coffee with your peers and of course the token giveaway raffles.

Today I am working the Balluff booth in the Sensors and Switches Virtual show.  It is a collection of companies and attendees from many different industries.  I really enjoy these events because we can contact quickly with potential customers and potential vendors right from the comfort of our conference room and at a much reduced cost. Here you can see our hard working staff chatting with customers.

Check out the Balluff booth at the  Sensors & Switches Virtual Tradeshow, it will be available to visit for 90 days from today.

3 Common Applications for Discrete Output Inductive Proximity Sensors

Written by: Jeff Himes

Discrete (off/on) output inductive proximity sensors are used in a multitude of markets and industries.  The number of inductive sensors sold each year is in the millions.  With that many pieces being sold each year, one has to ask – how are all of these sensors being used?  Their uses break down into 3 common applications.

The 3 most common applications for discrete inductive proximity sensors are:

1.) Machine position verification

2.) Part position verification

3.) Part feature verification

The Killer Application for Capacitive Sensors

Written by: Bjoern Schaefer

Capacitive sensors certainly serve a niche within the group of proximity sensors.  This niche makes people overlook the most striking feature this technology provides us – remote detection of any liquid through glass or plastic walls.  On the first look that does not sound too exciting and I agree, as long as you have not been tasked to specify a sensor to accomplish this very job.

Shedding the Light on Diffuse Mode Photoelectric Sensors

Share/Bookmark

Photoelectric sensors have solved numerous industrial applications over the years. There are basically three different sensing modes. The first is diffuse or reflex mode, next is retro reflective, which requires a reflector, and the third is through beam, transmitted or opposed. These field devices provide an excellent means of detecting target at a distance without contacting the object. All of the sensing modes are based on the sensor’s ability to detect a change in light reaching the sensor’s receiver. In this posting, we will review the diffuse or reflex photoelectric sensor.

8 Selection Criteria to Remember When Choosing an Inductive Sensor

Written by: Jeff Himes

Selecting the correct inductive proximity sensor for an application can be an intimidating process.   There are literally thousands of models available from various vendors so having a good starting point to narrow down the field is essential.

At this point is will be assumed that an Inductive Proximity Sensor is the type of sensor being selected.  If you are at the beginning of your selection process, please read and earlier blog post pertaining to your initial sensor selection.
