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.

Inductive sensors for mobile equipment
The vehicle’s design engineer is most interested in how our sensors will perform with all of the dynamic stresses the sensors will be subjected to during the life of the vehicle, so here are the top 10 questions regarding the use of sensors for position detection on mobile equipment machines.

Top 10 questions asked about mobile equipment inductive proximity sensors

  1. Will inductive proximity sensors survive outdoor temperatures?  Yes, our mobile equipment inductive proximity sensors are tested and approved for operation in the range of -40 °C to +85 °C. 
  2. Will radio frequency noise interfere with inductive proximity sensors?  Our mobile equipment sensors are designed to operate error free in fields up to 100 V/m.
  3. Can your mobile equipment sensors operate at 48 Vdc?  Our family of mobile equipment sensors are designed to operate from 10-60 Vdc.
  4. Can your mobile equipment sensors be wired in series?  Yes, as most mobile equipment applications have a 12 Vdc system, the ≤2 Vdc voltage drop of the output allows two sensors to be wired in series.  We also have relay and special low voltage drop solid-state outputs to allow four or more sensors to be wired in series.
  5. Can your mobile equipment sensors survive rain, snow, and heavy wash-downs?  With an IP68 and IP69K rating, our mobile equipment sensors are perfectly suited to perform in the heaviest rain and wash-down applications.
  6. Can a Deutsch or Packard connector be added to the Pepperl+Fuchs mobile equipment sensor?  Absolutely. The standard 18 AWG wire accommodates the connector pin size requirements for a strong and reliable connection.
  7. Can your mobile equipment sensors survive exposure to fuels, oils, and road salt to which they will be exposed throughout the course of operation?  Without question. Our mobile equipment sensors have been laboratory tested and exposed to hundreds of thousands of hours in the field to all kinds of fuels, oils, and road debris performing well year after year. 
  8. Can Pepperl+Fuchs’ mobile equipment sensors be painted?  Most certainly they can.  The inductive sensing technology sees right through non-metallic materials such as plastic and paint.  So feel free to paint the sensor to your company’s identified color scheme. 
  9. Can inductive proximity sensors be damaged by the electrical noise on the vehicle’s power system?  Yes they can. However, our mobile equipment sensors have spike and noise suppression built in to the power inputs to prevent damage from occurring and ensure continued operation.
  10. What happens if your mobile equipment sensors are wired incorrectly or shorted to ground while power is applied?  All of our mobile equipment sensors are short circuit, overload, and reverse polarity protected.
