What is a Color Mark Sensor?

We are Color Mark Sensors | TL50 Sensors Suppliers in Mumbai, India. The Mark Sensor, also known as a contrast sensor, is an advanced optical sensor whose design is planned for detecting the difference in contrast between a mark, including a printed registration mark, and the background. These sensors find their main applications in packaging, food processing, cosmetics, and pharmaceuticals, among other industries, where high-precision detection of marks or labels on moving items may be of paramount consideration.

Color Mark Sensor

Types of Mark Sensors:

  • Photoelectric Sensors: Use a light source and a receiver to detect changes in light caused by the mark.
  • Contrast Sensors: Designed to detect subtle differences in colour or brightness between the mark and its background.

TL50 Series

The TL50 Series Mark Sensor is a prime example of this type of sensor. The TL50 Series Mark Sensor uses technology called RGB LED emission which provides very high resolution to detect the minutest of colour or grayscale differences between a mark and its surrounding background. Let's take a complete look at what the TL50 mark sensor is, its functionality, and its industrial significance. Advanced optical TL50 Contrast Sensors are designed to perform in high-performance colour and grayscale contrast detection applications. The sensors provide affordable solutions without compromising the detection capability, which makes them highly effective in industries related to packaging, food, cosmetics, and pharmaceuticals.

How Does the TL50 Series Mark Sensor Work?

The TL50 Series uses RGB LED emission that automatically selects the optimal light colour depending on the mark it detects and the contrast with its background, whether it be red, green, or blue. In other words, this feature offers the highest possible quality in detection accuracy.

Installation and Setup

Mount the sensor in the application area. Set sensing points by adjusting positions and pressing the teach button to save the desired distances. The sensor comes pre-configured for Normally Open (NO) digital output and positive slope analogue output. Configurations can be changed by holding the teach button for 8 to 12 seconds.

Working Features of TL50 sensor:

  • Contrast Detection: The sensor detects the difference between a mark and its background according to reflectivity. Integrated RGB LEDs automatically adjust to the optimal colour wavelength, which allows for subtle contrasts that no other sensor can provide.
  • Threshold Auto-AdjustmentThis sensor is equipped with two push buttons, MARK and BKGD, respectively, from which it can easily pick up signals from both mark and background. It will automatically set a switching threshold level to differentiate between the two, thus optimizing detection.
  • High Resolution with SpeedContrasting the high resolution offered, the TL50 sensor provides very fast response times down to 33 µs, with a switching frequency of 15 kHz, making it suitable for high-speed applications where even minor time delays can affect production lines.

Key Features of TL50 Series Mark Sensor

  • RGB LED Emission: The sensor provides red, green, and blue LEDs that detect contrast either between colours or shades. It makes the above sensor versatile on a variety of materials, even those with a transparent or glossy finish.
  • Durable Plastic Housing: The sensor head is manufactured in sturdy ABS plastic, therefore rugged and reliable for long-term industrial use. The housing also contains standard dimensions and fixing holes to grant compatibility with existing systems and to easily install it.
  • Easy Sensor Setting: The two push buttons MARK and BKGD make user-friendly the calibration phase of the sensor. This way, the operators can rapidly set the sensor to match the required setting with high precision.
  • Fast Response Time and High Switching Frequency: With a response time of 33 µs and a switching frequency of 15 kHz, the TL50 matches fast-paced production lines with real-time marking or labelling detection.
  • Automation of Light/Dark Selection: It automatically selects if the mark will be lighter or darker than the background to further simplify its operation and maintain accuracy in dynamic environments.
