A color mark sensor is a type of sensor that is used to detect and differentiate between different colors on a surface. It is commonly used in manufacturing, packaging, and printing applications, where it is important to detect and locate color-coded objects or labels.

Color mark sensors work by emitting light onto the surface being scanned and measuring the reflected light. The sensor can then determine the color of the surface based on the wavelength of the reflected light. Some color mark sensors use RGB (red, green, blue) LED technology to emit light of different colors, allowing for even more precise color detection.

Color mark sensors are often used in conjunction with other types of sensors, such as registration mark sensors, to ensure accurate positioning and detection of color-coded objects. They can be integrated into automated systems to provide real-time feedback and control over manufacturing or packaging processes.

Overall, color mark sensors are an important tool for ensuring accuracy and efficiency in a variety of industrial applications. Their ability to quickly and accurately detect and differentiate between colors can help to improve production speeds, reduce errors, and increase overall quality control.\

The code P1KH019 refers to a Wenglor Reflex Sensor with Background Suppression. This photoelectric sensor is specifically designed to detect objects with difficult surfaces, such as dark and shiny objects, and reliably distinguish them from the background. Key specifications

• Sensing method: Diffuse reflective with background suppression.
• Light source: Blue light, which is effective for detecting challenging surfaces like solar wafers.
• Range: 150 mm.
• Switching frequency: 1,000 Hz.
• Output: PNP with an M8, 4-pin connection.
• Input/interface: Can be configured using an IO-Link interface.
• Housing: Plastic (ABS/PC) with an IP67/IP68 rating, making it suitable for industrial use.
• Temperature range: -40 to 60 °C.
• Supply voltage: 10 to 30 V DC. 

ApplicationsThe P1KH019 is especially useful in industrial settings where the consistent detection of objects is critical, such as in the manufacturing of solar wafers. Its blue light source and background suppression feature allow it to overcome detection challenges posed by dark or highly reflective objects

The reflex sensor with background suppression works with red light according to the angle measurement principle and is suitable for the detection of objects against any background. The sensor always has the same switching distance, regardless of the color, shape and surface of the objects. Minimal height differences can be detected with the sensors and, for example, various parts can be reliably differentiated from each other. The IO-Link interface can be used to configure reflex sensors (PNP/NPN, NC/NO, switching distance) and to output switching statuses and distance values.

Features at a Glance

• Condition monitoring
• Low switching distance deviation for black/white
• IO-Link 1.1
• Reliably detect objects against any background

These sensors have been specially designed to recognize print marks. They have a very small spot and use a white light LED with long service life. Only one sensor is required for the recognition of all color combinations, as well as the difference in brightness between print marks and the background.

The product code P1KH001 refers to a reflex sensor with background suppression manufactured by Wenglor. This type of photoelectric sensor uses red light and an angle measurement principle to reliably detect objects, regardless of their color, shape, or surface texture, even against a reflective or bright background.

Key specifications

• Sensor Type: Reflex sensor with background suppression.
• Light Source: Red LED light.
• Range: Up to 150 mm.
• Adjustable Range: The detection range is adjustable from 30 to 150 mm.
• Detection Method: Works on the angle measurement principle, making its detection distance independent of the object's color or surface properties.
• Interface: Features an IO-Link interface for configuration, status monitoring, and reading distance values.

• Electrical Data:
  • Supply Voltage: 10–30 V DC.
  • Current Consumption: Less than 20 mA at 24 V DC.
  • Switching Frequency: Up to 1000 Hz.
• Physical Features:
  • Housing Material: Plastic.
  • Protection Rating: IP67/IP68.
• Temperature Range: -40 to +60°C

Common applicationsThis type of sensor is particularly useful in industrial automation for tasks such as: 

• Detecting objects against any type of background, including reflective or bright surfaces.
• Distinguishing between parts of varying colors and shapes.
• Reliably detecting minimal height differences between objects. 

The term P1KH002 is not a chemical formula, but rather the model number for a specific photoelectronic sensor manufactured by the company Wenglor. About the P1KH002 sensor

• Type: It is a reflex sensor with background suppression. This means it uses a red light beam to detect objects, and the background is essentially "ignored" so it can detect minimal height differences.
• Operating range: The sensor can be used at a range of 30–150 mm.
• Function: The sensor is designed to detect objects reliably, regardless of their color, shape, or surface texture. This makes it useful for industrial automation applications like robotics, machine tools, and assembly lines.
• Interface: It has an IO-Link interface, which allows for configuration of settings such as PNP/NPN outputs and switching distance. It can also be used to read switching statuses and distance values.
• Durability: The sensor is rated for ingress protection IP67 and IP68, indicating high resistance to dust and water.
• Construction: The housing is made of ABS/PC plastic, and the optic cover is made of PMMA plastic.
