Does My Application Require a NAMUR Output Sensor?

Posted by Andrew Hund on Fri, Aug 25, 2017

NAMUR sensors solve the same applications that standard inductive and capacitive sensors or rotary encoders would—but they are safe to use in hazardous areas. NAMUR output sensors are ideal for applications where the presence of a volatile gas, vapor, dust, or fiber creates a possible hazard.


To prevent an explosion in hazardous areas, these sensors protect the circuit by operating at 8.2 V and less than 5 mA. These levels prevent the device from storing sufficient energy to initiate an explosion. NAMUR sensors are connected to an isolating amplifier, which limits the current and voltage to the sensor and amplifies the signal upon return.

Did You Know That Most Sensors Are IO-Link Sensors?

Posted by Tim Cicerchi on Fri, Oct 21, 2016

Many of the sensors you use have IO-Link capability built in. But you might not know it, because they can still be used like standard sensors. For instance, all Pepperl+Fuchs IO-Link sensors boot up first in digital IO mode; they will only switch to IO-Link mode when an IO-Link master actively communicates with them.

Anti-Swing Software and Inductive Sensors Raise Your Mobile Equipment to a Higher Level

Posted by Patricia Stafford on Thu, Jul 07, 2016

Controlling the motion of cranes, hoists, and other mobile equipment while avoiding accidents is a vital part of ensuring their safe and efficient operation. Vertical lift applications can be trickier and pose greater risks than working with horizontal conveyor belts, which tend to be more steady and predictable.

Is Environmental Heat Getting the Better of Your Optical Sensors?

Posted by Tom Anderson on Thu, Sep 24, 2015

Ed. Note: This guest blog post is by Tom Anderson, General Manager of PSI Technics, LTD. and is cowritten with Ann Zecha of WordSpark, LLC.

Radiant heat from manufacturing processes in high-temperature environments can present a challenge for optical sensors used in automated production facilities. Excessive heat in melting, pouring, or similarly demanding industrial applications that exceeds a sensor’s temperature specifications can degrade the measurement quality, damage sensor diodes, and cause unwanted disruption to production. Usage statistics show that for every 18 °F (10 °C) increase in temperature, the diode lifespan of optical sensors is reduced by up to 50%.

Boosting Productivity with the Help of Laser Barcode Scanners

Posted by Tim Cicerchi on Thu, Jun 25, 2015

Laser barcode scanners have been used in material handling applications for decades.  It is an integral part of routing boxes down a conveyor line.  The production of products such as liquid soaps, lotions, and shampoo will use barcode readers also.  They are used in two places.  First, to read the pallets of raw material bottles at the beginning of the production line, then secondly, at the end of the line after barcodes are applied to the bottles.  The barcode readers have to read at very high read rates of over 200 bottles per minute.

How Do Inductive Sensors Respond to Stainless Steel?

Posted by Tracy Molnar on Thu, May 22, 2014

Inductive sensors are designed for the detection of metal targets at close range and are a popular choice for use as proximity switches in factory automation applications.  Carbon steel is the typical target material for these sensors, but in some industries, stainless steel is more common.  There are also certain cases when either both types of steel must be detected by the same sensor, or one sensor is needed to be able to distinguish between the two.
