Description
Product Introduction
This industrial laser distance sensor is a high-precision non-contact measuring device designed for industrial automation applications. It supports a maximum measuring distance of 22 meters and performs stably even under strong sunlight, low-reflection targets and complex field conditions. Built-in temperature compensation and reflectivity correction ensure consistent and accurate readings for objects of different colors and materials. With IP65 waterproof and dustproof rating, wide voltage input, and multiple anti-interference designs, the sensor works reliably in high/low temperature, dusty and harsh industrial environments. Equipped with NPN/PNP switch output, RS485-Modbus and 4-20mA analog output, it is widely compatible with PLC and industrial control systems, easy to install and debug for intelligent distance detection and positioning.
-
Long Measuring Range & Strong Environmental Adaptability: Max distance up to 22m; 15m under 160kLux strong light; 20m for 10% low-reflection black targets, suitable for various complex working conditions.
-
High Precision & Excellent Repeatability: Graded precision control with repeatability of ±8mm~±30mm in different ranges, supporting stable dual-target detection for industrial precise measurement.
-
Intelligent Calibration Algorithm: Supports temperature compensation and reflectance correction. Measurement deviation for different colored targets is less than 5mm, effectively avoiding data drift.
-
Industrial Grade IP65 Protection: -20℃~50℃ operating temperature and -40℃~85℃ storage temperature, dustproof and waterproof for outdoor and harsh workshop use.
-
Adjustable High Frequency Response: Measuring frequency 1~1000Hz (default 100Hz), fast response for dynamic distance measurement and high-speed assembly line detection.
-
Multi-output Compatibility: Integrated NPN/PNP digital output, RS485-Modbus and 4-20mA analog output, fully compatible with mainstream industrial PLC systems.
-
Safe & Durable Performance: Adopts 905nm Class 1 safe laser, with reverse connection protection and isolation circuit. Service life over 50000 hours for long-term industrial operation.
-
Compact Size & Easy Installation: Mini ABS housing with 4-digit LED display and physical buttons for threshold and range adjustment. Comes with mounting screws for flexible embedded installation.
