Sensors sort the good from bad

The expanded Mini range of registration sensors from German sensing specialist Sick Reliable is said to provide high-speed contrast, colour and luminescence detection on packaging.

Additions to the Sick range are the KTM Prime Inox sensor for hygienic environments, in both hot and cold processing applications; the CSM colour sensor, for detection, checking and sorting of objects according to colour; and LUTM luminescence detection sensor, used to detect fluorescent marks.

The LUTM is used for detecting non-visible registration and print marks and for label and packaging security applications.

Each new sensor is said to have excellent switching frequency and delivers high machine productivity for a wide range of matt and glossy packaging materials.

“Each Sick Mini packs a mighty punch into a small sensor to be able to detect contrast, colour or luminescence reliably in even the most difficult circumstances,” says David Hannaby, Sick’s product manager for presence detection.

“The three-colour LED [light emitting diode] and smart ASIC [application-sensitive integrated circuit] onboard intelligence ensure that markings and colours will register despite being low contrast.”
