Key Benefits

Precise color and contrast detection for challenging applications

The QCM50 sensor precisely verifies slight variations in target color at all distances within the sensing range (from 18 mm to 150 mm, depending on the model). The white LED allows the QCM50 to detect a wide variety of targets—including dark, multicolored, and reflective surfaces—that are challenging to traditional sensors.  Color sensitivity is adjustable to meet the application’s tolerance requirements.

The versatile color sensor is available in:

  • Long-range models (up to 150 mm),
  • Small spot models (4 x 4 mm spot at 40 mm) for very small targets like registration marks or specific colors on a varied background, and 
  • An anti-glare model to reliably differentiate reflective surfaces such as packaging tape or foil. 

Reliable Performance in Harsh Environments

The QCM50 sensor features a rugged metal housing rated IP67 and IP69 for reliable, low-maintenance operation in harsh, washdown conditions.

Intuitive configuration and monitoring

The QCM50 is easy to program and troubleshoot using the onboard buttons and large integrated backlit display, which provides more intuitive, visual confirmation of sensor settings compared to traditional alphanumeric displays. The sensor can also be configured and monitored remotely via IO-Link. With IO-Link, users can visualize Red, Green, and Blue and total light intensity values of each target, for extremely fine color differentiation.

The QCM50 sensor can be configured using two different modes: color mode and best fit mode.  In color mode, the sensor is configured to validate a taught color within a specified tolerance.  In best fit mode, the sensor intelligently matches the target to the closest taught color, for applications where the sensor should always provide an output indicating the closest color match, regardless of small color variations.

Faster changeover with fewer devices

Depending on the model, the QCM50 color sensor can store up to 12 different colors in onboard memory to verify a diverse spectrum of product colors with a single device, saving hardware and maintenance costs. Once configured, the QCM50 sensor automatically matches all colors simultaneously, with no reprogramming required between batches, for faster changeover and less downtime.

Applications

The QCM50 color sensor is an ideal solution for a wide variety of applications including:
  • Product differentiation 
  • Color verification, including confirmation of correct shade
  • Automotive component inspections verifying color and material
  • Distinguishing between polished and non-polished metal surfaces
  • Detecting clear or translucent film on a reflective background, and other applications with mixed materials and minimal color differences
  • Lid or label inspection
