Treotham will distribute a range of print mark sensors designed to recognise print marks, stamps, and labels at high speeds.
From Wenglor, the WM03 series of sensors use a white LED light with a long service life, and produce a small light spot.
Only one sensor is required to recognise all brightness and colour combinations between the print mark and the background, and it can differentiate up to 100 grey levels.
The print mark sensors detect up to 20 grey levels and can be adjusted to suit any application using several teach-in modes.
The deactivation of the output can be put forward by using the connectible time delay function.
The WP02 and WP04 series are characterised by a small spot of light and high contrast resolution.
The high switching frequency and various teaching modes are adjustable to any application, and the threshold can be manually adjusted.
