Color Detection Sensor


Micro Epsilon colorSENSOR OT-3-LD Fixed Lens Color Sensor with Integrated Controller, 50 mm-800 mm Object Distance & 23 to 50 mm Light Spot Diameter

SKU: colorSENSOR OT-3-LD Category:

The colorSENSOR OT sensors are ideal for color determination from a large distance according to the True Color method. The OT series consists of sensor types with different working distances and spot sizes. The sensor housing of the OT3 color sensors includes the detector, the evaluation unit and the illumination so that no external controller is required. A key on the sensor housing enables to teach in 31 colors/color groups. Using the separate configuration software, the sensor can be adjusted to the current measuring situation. If the sensor recognizes one of the taught colors, the color group is output via the corresponding digital switching outputs. The OT sensor is also suitable for detecting the color of self-luminous objects. For this purpose, the internal illumination can optionally be deactivated via the software.
