E32 Special application

Features

Special application fiber sensor heads

For a wide range of special applications, the task optimised fiber heads provide best fitting sensing performance and adaption to environmental requirements.

  • Detection of special objects (liquids, transparent foils, etc.)
  • Fiber heads ideal for colour mark detection
  • Fiber heads optimised for special tasks (wafer mapping, hot reflective surface detection, etc.)

Challenging print marks

In combination with the colour/mark detection amplifier E3X-DAC-S, the recommended fibers for colour/mark detection allow the detection of standard and challenging marks even for complex designs or with small contrast.

Flat glass in all environments

Performance comparison

Usable signal and noise

Issue 1: Increasing the difference between usable signal and noise

The goal of any transparent sensor development is to increase the difference between usable signal and noise.
And the operational stability of the sensor depends on how well the following factors are achieved:
  • Compensating for dirt and water on the lens
  • Temperature compensation
  • Changing ambient light immunity
  • Electromagnetic noise immunity

Our solution:

At Omron we take several steps to increase the operational stability by maximising the difference between signal and noise:
  • In design: circuit layouts, shielding, filtering technologies and material selection ensure a minimal background noise and highest environmental influence compensation.
  • In technologies: in addition to using the retro reflective technology with standard polarisation technology, some materials e.g. PET have characteristics that additionally polarize light. This effect can be utilized further to enhance the difference between usable signal and noise.
  • In production: production technologies that allow a minimal deviation from the desired target specification values ensure that the performance of a sensor evaluated at the design-in phase does not vary during mass machine production.
  • In application: the selection of the fitting sensor in combination with choosing an appropriate mounting and parameter setting can further enhance the operational stability and/or detection accuracy.

Compensating for optical effects

Issue 2: Compensating for optical effects

As light travels through differing transparent materials (glass/PET) the following detection errors can occur:
  • Lens-effect: transparent objects with convex shapes (e.g. shower gel bottles) can perform like a lens and allow too much light to be received by the sensor. This can result in a false reading that no object is present or it can cause a so-called double-triggering (2 signals for only one object).
  • Total reflection: if the emitted light meets the surface of a transparent object at a certain angle, the light can be totally reflected instead of going through the transparent object. If the totally reflected beam hits the receiver, it can falsely result in a "no object" reading.

Our solution:

At Omron we use special coaxial optics for our higher value and application specific sensors. These special coaxial optical sensors reduce or completely eliminate the above described optical effects. Cylindrical sensors utilise the coaxial optics to prevent false signals caused by incorrect installation or turning sensors using conventional separate sender and receiver optics.

Process related requirements

Issue 3: Process related requirements

In order to select the correct transparent detection sensor taking also machine and process related issues into consideration is very important:
  • Minimal space between bottles
  • Conveying speed of the bottles/containers
  • Object size or shape (miniature objects, flat glass, etc)
  • Limited mounting space or long distances
  • Hot, wet or hygienic environments
  • Detection of container and content at the same time (e.g. vial and plug, vial and lyo cake, glass syringe with or without protective cover,…)
Application examples detection of 2 states with one sensor:
  • State 1: Transparent container + object present e.g. plug, lyo cake or syringe cover (OK state)
  • State 2: Transparent container WITHOUT object (not OK state)

Our solution:

At Omron we have a global network of application engineers. Their technical knowledge and experience will assist you and your company in making the correct product selection to fit your organisation industrial automation requirements and needs. What can we do for you?
