Optical Sensors

CAPTRON's Optical Sensors are robust, durable and reliable. They detect metallic and non-metallic objects from a size of 0.05 mm with extreme precision. In addition to laser light barriers with varying fork widths, CAPTRON also offers Tool Center Point (TCP) laser measurement devices for the exact measurement and calibration of robots.

The wide range of available designs and sizes are specially adapted to the requirements in automation, robotics and assembly. Our hardware solutions are robot-agnostic and in addition to highly technical recalibration can be used as a simple verification tool to ensure accuracy.

Tool Center Point (TCP) Optical Laser Sensors

CAPTRON's TCP Optical Laser Sensors provide a robust, durable, and reliable solution for ensuring accuracy and efficiency. In this video we demonstrate how to easily calibrate your UR robot with our innovative URCap software and our optical sensors. Follow the entire calibration process step by step and learn how our solution makes your robot applications more precise and efficient.

As a UR+ partner, we have taken the integration of our TCP measurement technology with UR robots to a new level. With our URCap, monitoring and adjusting the Tool Center Point is automatic. Our system is tested and certified by UR to provide you with seamless and precise results.

Fork Light Laser Sensors

As production volumes and speeds continue to rise, the expectation is that mechanical processes will minimize errors. CAPTRON Fork Light Laser Sensors help meet this demand with a precise laser beam transmitted between two arms—one acting as the transmitter and the other as the receiver. These sensors can instantly detect errors, count, account for web tensioning control and more.

    How to Maintain Robot Accuracy with Automated Tool Center Point Measurement

    Tool wear, maintenance activities, environmental conditions, and tool changes can all affect the accuracy of a robot's movements. Even small deviations can lead to quality issues, increased scrap rates, and costly downtime.

    How to Set Up TCP Calibration on a Universal Robot: Step-by-Step Guide

    Accurate robot motion begins with an accurate Tool Center Point (TCP). Once a TCP has been established, every programmed robot movement is calculated relative to that point. If the TCP is configured incorrectly, positioning errors can affect product quality, increase scrap, and create unnecessary troubleshooting during production.

    Automating TCP Calibration with Universal Robots: How URCap Software Improves Accuracy and Uptime

    While many manufacturers establish a TCP during initial robot commissioning, maintaining that accuracy over time is often the greater challenge. Tool wear, collisions, thermal expansion, and routine maintenance can gradually shift the TCP without operators noticing.
