SPECTRO-2 has 2 contrast sensors, allowing it to calculate other parameters.
The sensors of the COAST Series (COlor And STructure) are hybrid sensors that comprises two sensors that only are synchronized by the LED ring light but otherwise operate independently of each other. Both sensors can be connected to a PLC or to a PC.
SI-COLO3 and SI-COLO4 series sensors operate by using 3-color-range method.
Devices of SPECTRO-3 series are designed to detect “true-color” (human color reception). Sensors can be used in AC or DC modes, with internal or external light source.
