New from Omron is the E3S-DB, a transparent-object sensor specifically designed for the food and beverage industry which is said to offer better detection of objects such as glass bottles, PET bottles, transparent trays or packaging film.
To enable high-precision detection and positioning on conveyors where the smallest of gaps between bottles exists, the device is also available in narrow-beam models with a convergent beam that has a focused spot size of just 2mm at a distance of 200mm.
The E3S-DB sensors apply a technique known as P-Opaquing, which offers increased detection stability through special polarising filters for PET objects. A further advanced feature also automatically compensates for light-level changes caused by ambient conditions or contamination. Additional features include an optical system that enables sensing with low hysteresis and high dynamic range – it can, for example, detect just 3% light-intensity attenuation at a distance of up to 4m. Its advanced optical system also increases stability performance by completely cutting off even the smallest amounts of stray light that might
interfere with glass bottle detection.
Of additional benefit, setting up the instrument is quick and easy thanks to Omron’s ‘Smart Teach’ function; and information about the operational threshold of the sensor is always clearly visible. The operator can also easily copy the setting from one sensor to another.
