Recently, however, our distribution partner Contrinex released a new type of photoelectric sensor that offers an elegantly simple solution to this problem.

The new TRU-C23 photoelectric sensors use polarized UV light instead of visible light to detect the presence of transparent objects on assembly and packaging lines. Although transparent glass and plastics don’t absorb much visible light, they do absorb a great deal of polarized UV light. By using this quirk of the electromagnetic spectrum to their advantage, the engineers at Contrinex were able to create a photoelectric sensor that is perfectly suited for detecting transparent objects when partnered with the specially-designed reflector.

These sensors also offer an impressive operating range of about 1000 mm, as well as an industry standard IO-Link Interface. Their housings are also compatible with any of the sensors in the C23 series.

Locon also offers a solution in our Universal Heavy Duty Photoelectrics.  These sensors function reliably particularly in environments that present the challenge of dust or moisture accumulating on the lens.  There are special modifications we can suggest to meet the demands of specific application requirements.

In this case, we recommend the C23 series of photoelectric sensors from Contrinex.

Instead of relying on inductive properties, these sensors use ultraviolet light to detect nearby objects. The sensor contains both an LED that emits polarized UV light and a specialized reflector that bounces UV light back at the emitter.

Because transparent materials absorb large amounts of polarized UV light, photoelectric sensors are ideal for this type of application. When transparent objects pass between the emitter and reflector, the UV beam is broken and the sensor is triggered. Using photoelectric sensors to detect transparent objects will ensure that you avoid costly counting errors and equipment malfunctions.

These sensors are frequently used in food processing plants to detect transparent bottles and other containers. They come in a number of different configurations to suit transparent materials of varying sizes and thicknesses. The C23 Transparent Standard sensors have a maximum operating range of up 2500 mm. Other smaller C23 sensor options have operating ranges of about 1000 mm. At just 30 X 20 X 10 mm, the sensor housings are also small enough to be installed in tight, restricted spaces.
