Micro-Epsilon Group Color Sensor for High Offset Distances colorSENSOR OT-3-LD-500-50

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. Using a modulated white light LED, a white light spot is projected via the integrated lens onto the measuring object to be tested. Part of the light that is back scattered from the measuring object is directed onto a perceptive True Color detector element via the center of the lens, separated into long-, medium- and short-wave light components. Subsequently, it is transformed into L*a*b* color values. 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. The True Color sensors of the OT3 series are designed for measuring tasks where a large distance from the measuring object must be maintained.
