Sensing Minimum Gap Boxes on a Conveyor
In a manufacturing environment, a given operation, such as a box taping machine, may require or is most effective, if a minimum spacing or gap between consecutive boxes on its in-feed conveyor exists. This unique System is designed to solve that need.
Sensing Tape Presence on a Shipping Box
In the automation industry, tape is often applied automatically by a tape applicator machine to closed boxes traveling along a conveyor system. Since the tape is applied automatically and given that the tape is essential to retain the integrity of the goods within the shipper box, it is important for the manufacturer shipping the goods to ensure that the box did get tape applied, and was not missed.
Ultrasonic Sensing with a Background
In industrial automation applications, often the task of a sensor is to continually and reliably sense the presence of an object from leading- edge to trailing-edge.
Ultrasonic sensing is relatively new, or at least new to a lot of newer engineers and maintenance personnel.
Lasers are a subset of photoelectric sensing, with the distinction of having a well-collimated light beam.
Photoelectric sensing, as with many other sensors of different technology, can be applied in different modes of operation.
Inductive sensing has been used in the marketplace for a long time.
Capacitive sensing is using the dielectric effect to detect the presence of target materials.
Mechanical Limit Switch Sensing
Mechanical limit switch sensing is likely the first, and therefore the oldest method, in industry, of sensing the presence of some object.
UV sensing is an interesting subset of photoelectric sensing, but with some significant distinctions.
Sensing/Controlling Level of Powder Type Substance in Hopper or Bin
Loosely compacted powders can be challenging for sensors to detect. We found a solution!

One of the most difficult applications for a photoelectric sensor is to reliably sense the presence of a clear film or object in the retro-reflective mode
Photoelectric Through Beam with Fiber-Optics
One of the most challenging applications of photoelectric sensors with fiber-optics is to detect a small size part at a significant distance.
A customer was using a competitive, photo-eye sensor to a foil packet. The existing photo-eye was using a fiber-optic to detect when the packet came into view. When the packet was not present, the sensor’s fiber-optic was looking at black friction tape in the background. His sensor was missing packets altogether.
Sensing Registration without a Registration “Eye” Mark
Registration marks on films are used to indicate the occurrence of a printed pattern repeated on film. The challenge is that for any given color of graphics, as the film travels, other printed graphics will also pass in the sensor’s view, and the sensor won’t be able to distinguish one printed graphic from another.
Sensing Only Through a Duration of Target Passage
It is common in industrial applications to need a sensor to sense, display, and control the level in a tank. The challenge is to specify the level the sensors display, or control should correlate to.
