Use Photoelectric Sensors to Detect Transparent Objects

Automated manufacturing operations depend on sensor equipment to make sure each step of the process is completed reliably and effectively. For many applications, inductive sensors can do a fine job of monitoring and maintaining the automated manufacturing process. When working with glass or transparent polymers, however, you need a different type of sensor.

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.
