My Old Industrial Sensor has 4 Pins

Posted by Tracy Molnar on Thu, Oct 17, 2013

…and the replacement only has 3 – can I still use it?

It’s always a good idea to double-check that a different-looking industrial sensor will work as a replacement for your currently-installed part, because looks can be deceiving.  Take for example the question above regarding the number of pins in a sensor’s connector.

Top 3 Questions About AS-Interface Accessories

Posted by Tim Cicerchi on Fri, Sep 27, 2013

AS-Interface was designed for factory automation.  One of the requirements was quick installation to a flat cable.  The flat cable allows a module to pierce directly into it.  If for some reason in the future you need to move the module or add another module, it is very easy to make additional connections to the flat cable.

Do I Need a Cordset for My Sensor?

Posted by Tracy Molnar on Fri, May 03, 2013

Different sensor connection types

Electronic sensors require connection in order to receive their power and transmit their output.  A connection diagram, included on the sensor’s datasheet and often printed on the device if room allows, labels each available connection point.

How to Calculate Fieldbus Cable Voltage Drop

Posted by Bernd Schuessler on Fri, Mar 08, 2013

When designing FOUNDATION™ fieldbus or PROFIBUS PA networks, it is extremely important to make sure that the devices on those networks have enough power to start up properly and operate normally.

The fieldbus physical layer specification IEC 61158-1 defines the min/max voltage levels for FOUNDATION fieldbus and PROFIBUS PA. The minimum voltage required for any fieldbus device is 9 V and the maximum voltage allowed on a fieldbus network is 32 V.

To calculate the voltage drop along a fieldbus cable, you must know the number of connected instruments and their current consumption, as well as the resistance of the cable, cable length, and power supply voltage. Typical fieldbus devices consume 15 mA to 20 mA. The exact number can be found on instrument data sheets. A standard “type A” fieldbus cable has a typical resistance of 44 Ohm/Km and a typical fieldbus power supply supplies 30 V.

Knowing the total current draw, supply voltage, cable resistance, and cable distance of a segment, and applying Ohm’s law, allows you to deliver maximum distance and/or voltage drop at a certain distance.

To simplify these calculations, companies like Pepperl+Fuchs have created free-of-charge segment design tools like Segment Checker.

Fiber Optic Cables for Photoelectric Sensors: The Best Thing Since Sliced Bread

Posted by Joan Kassan on Wed, Mar 06, 2013

Photoelectric sensors are used in a diverse combination of applications and industries. While most applications operate at a temperature range that falls between -13 °F and +150 °F,  many industries have applications that are located in extremely harsh environments and temperature ranges that fall well above and below these levels.

Top Ten Questions Asked About Mobile Equipment Sensor Applications

Posted by Joe Fye on Thu, Feb 28, 2013

For companies who develop and manufacture large mobile equipment vehicles, sensors are a vital part of the control package for feedback to the processor.  These sensors directly inform the processor of the status and position of the various processes throughout the vehicle.  They must perform flawlessly for the vehicle to complete the function for which it was manufactured.
