AutomationDirect now offers Datalogic print mark contrast sensors with 6-12mm sensing distances. Designed to detect the difference in the wavelength of the reflected light between a target mark and background, the contrast sensors use RGB light emission with automatic selection, and feature teach-in sensitivity adjustment, and selectable light on/dark on outputs.
The S8 Series compact contrast sensors feature horizontal spot orientation, a 25 kHz switching frequency, NPN or PNP logic output, 12-30 VDC operating voltage, and are available with IP67-rated plastic or IP69K-rated 316L stainless steel housings. The S8-series sensors, are fitted with a 4-pin M8 quick-disconnect or have an attached 150mm cable with M12 quick-disconnect.
New TL Series contrast sensors feature vertical or horizontal spot orientation, 10-30 VDC operating voltages, aluminum housings, and NPN/PNP or PNP logic outputs. TL-series sensors are fitted with a 5-pin M12 quick-disconnect with adjustable exit angle; models are available with 0-5VDC analog outputs and 15, 20, or 50 kHz switching frequencies. The TL series are IP67-rated contrast sensors.
In this HOW TO video, I will demonstrate how to setup background and targets with the Datalogic contrast sensors that we sell here at AutomationDirect. Here I am setting up different contrast colors on a photo video color sheet as target and background. In previous videos we used a color wheel and set the target and background as 2 colors or 2 contrast colors. Here we setup the target and background with many different combinations of colors as targets and backgrounds including close color combinations. We also wire up a simple 22 millimeter push button to demonstrate the remote input capability. Instead of using the set push button on the sensor, the white wire is wired to a push button with positive voltage. When the push button is pressed, the sensor detection functions can be set. This sensor also has a key lock function but does not have a key lock graphic on the sensor or a key lock LED like the TL46 models. This key lock function locks or is activated when the remote wire is connected to positive voltage DC for at least one second. In order to deactivate the key lock, the sensor must be turned off and re-powered with the remote wire NOT connected or connected to ground. I hope you found this video useful and follow us to our other How to videos on the Datalogic Contrast Sensors. Thanks and have a great day.
