Specification notes
Q1: What is the TAKEX CST-R85?
A: The CST-R85 is a high-precision passive-type color sensor that identifies color ratios and brightness through R/G/B light-receptive elements.
Q2: How small a color difference can the CST-R85 discriminate?
A: It can discriminate LED color-ratio differences down to 0.01%.
Q3: Can the CST-R85 detect both color and brightness?
A: Yes. It provides one output for color-ratio identification and a second output for brightness identification.
Q4: Can the CST-R85 detect pulse-lighting sources?
A: Yes. The CST-R85 supports pulse-lighting LED sources.
Q5: Does the CST-R85 support both NPN and PNP outputs?
A: Yes. NPN and PNP open-collector outputs are selectable, with a maximum load current of 50 mA at 30VDC.
Q6: How many reference colors can be registered?
A: The CST-R85 registers one reference color through teaching.
Q7: What teaching methods are available?
A: One-point and two-point teaching are available, together with an external no-voltage teaching input.
Q8: What response times are available?
A: Response time can be set to Auto, 50, 100, 250, or 500 ms or less. Auto mode can respond in 10 ms or less at maximum depending on target lighting conditions.
Q9: Can the CST-R85 discriminate the color of film and resin plates?
A: Yes. It can discriminate film and resin plate colors using color-ratio and brightness information.
Q10: What applications are suitable for the CST-R85?
A: It can be used with the CS-R85 for mixed-model lighting checks and lighting characteristics assessment, and for color discrimination of film and resin plates.
