The LX-100 series – a combined LED contrast and colour sensor – can be used both as a high-speed contrast sensor to quickly and reliably detect printer’s marks, for example, and as a high-precision colour sensor.
The LX-100 series – a combined LED contrast and colour sensor – can be used both as a high-speed contrast sensor to quickly and reliably detect printer’s marks, for example, and as a high-precision colour sensor.
In contrast sensing mode, the sensor automatically selects the optimum emitting LED during teach-in (static or dynamic teach-in method) from the transmitting light source (red, green and blue LEDs). With a response time of just 45µs, this sensor is perfect for high processing speeds like those required in printing presses, for example. In colour mode, an integrated microprocessor with a 12-bit A/D converter digitally processes the signals of the colour to be detected in red, green and blue primary colour components. This ensures that even the most minute colour differences or merest of tints can be accurately distinguished.
