COGNEX PS007-4GCKR Vision System Power Supply Module

Product Dimensions：

The Cognex PS007-4GCKR is a specialized accessory, specifically a Polarizing Filter Kit, designed for the Checker 4G series of vision sensors. It is used to eliminate glare and reflections from shiny or metallic surfaces, which is critical for obtaining high-quality images in machine vision applications.

Product Detailed Description

The PS007-4GCKR is an integrated optical solution that clips directly onto the front of a Cognex Checker 4G sensor (such as the 4G7 or 4G1). It consists of a polarizing film and a mounting bracket. In industrial environments where parts are made of polished metal, plastic, or glass, “specular reflection” (hot spots) often “blinds” the camera. This filter kit cross-polarizes the light, allowing the sensor to see the actual features of the part rather than the reflection of its own integrated LEDs.

Technical Parameters

Product Advantages

• Glare Suppression: Effectively removes “hot spots” from reflective surfaces like aluminum, stainless steel, or wet packaging.
• Toolless Installation: Designed for a quick snap-fit onto the Checker housing, allowing for field upgrades without disassembling the sensor or lens.
• Improved Inspection Accuracy: By normalizing the image contrast, it allows vision tools (like pattern matching or brightness checks) to operate more reliably.
• Compact Integration: Does not significantly increase the footprint of the sensor, maintaining the Checker’s ability to fit into tight machine spaces.

Important Considerations (Precautions)

• Light Intensity Drop: Polarization naturally reduces the amount of light reaching the sensor (often by 1–2 f-stops). You may need to increase the exposure time or the LED intensity in the Checker software after installation.
• Orientation: The effectiveness of a polarizer depends on its orientation relative to the light source. Ensure it is seated correctly as per the installation guide.
• Maintenance: Keep the filter surface clean. Use only non-abrasive optical wipes, as scratches or oil (fingerprints) on the polarizing film will degrade image quality.
• Specific to 4G: This specific “CKR” variant is tailored for the Checker 4G series; it may not fit the larger In-Sight 5000 or 7000 series without different adapters.

Product Applications

• Automotive: Inspecting shiny metal components, such as engine blocks, polished pistons, or chrome-plated trim.
• Food & Beverage: Detecting the presence of caps or labels on glass bottles and aluminum cans where overhead lighting causes blinding reflections.
• Electronics: Checking for component presence on shiny PCB surfaces or inspecting solder joints.
• Packaging: Reading codes or inspecting seals on glossy plastic film or metallic foil pouches.
