Product Introduction
A laser web guide sensor is a high-precision, non-contact position sensor used in web guiding (EPC) systems to detect the edge, line, or reference point of a moving web and provide fast, accurate feedback to the controller for lateral correction.
Main Features
- Features ultra-high accuracy, excellent linearity, and strong resistance to interference.
- Temperature Compensation Utilizes CMOS technology to eliminate baseline drift caused by seasonal and ambient temperature fluctuations, maintaining micrometer-level stability.
- Collimated Optics Employs near-ideal parallel light to suppress measurement errors, ensuring high precision over extended distances.
- CMOS Processing Algorithm Analyzes light and shadow patterns via pixel-level calculations to achieve a precision of 10μm.
Core applications
Designed for high-precision applications such as lithium battery and high-performance film production lines, and also suitable for outer diameter and width measurement.
