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.

The Secret of IP67 Protection

Over the last year I have been discussing IP rated products with people in various positions  in the manufacturing world and I have encountered some false assumptions about IP67 protection.  I want to quickly go over what an IP67 test actually is and then go into the assumptions I’ve seen.
