The KLSA series laser ranging sensors for industry and manufacturing
Introduction
The KLSA series laser ranging sensors are advanced industrial-grade solutions designed to meet the precision measurement needs of manufacturing and industrial applications. Leveraging cutting-edge laser technology, these sensors deliver reliable non-contact distance measurement with high accuracy and durability, ensuring seamless integration into automated production lines, quality control systems, and equipment monitoring.
Key Features
- Precision Measurement: Measures distances from 0.03 to 22 meters with fixed accuracy, ideal for monitoring component placement, assembly gaps, or material flow in industrial environments.
- Dual Signal Output: Supports RS485 (MODBUS-RTU protocol) for digital communication and 4–20mA analog signals, enabling compatibility with PLCs, SCADA systems, and other industrial control devices.
- Hysteresis & Window Functions:
- Hysteresis function stabilizes output switch states by setting threshold ranges, preventing signal fluctuations caused by minor distance variations.
- Window function monitors objects within user-defined near and far switch points, triggering alerts or actions when objects enter/exit specified zones.
- Background Suppression: Filters out reflections beyond 22 meters, minimizing interference from distant machinery or environmental clutter.
- User-Configurable Settings:
- Intuitive 4-digit display and button controls (MODE/SET) for on-site parameter adjustment, such as laser status, analog output ranges, and communication baud rates (9600–115200 bps).
- Programmable output modes ([Hno/Hnc/Fno/Fnc]) via menu settings, adapting to diverse industrial control requirements.
- Industrial-Grade Design:
- DC 9–35V power supply with isolation, compliant with EN 50178 and safety standards.
- Rugged construction ensures reliability in harsh environments, with professional installation and maintenance support.
Applications
- Production Line Automation: Monitors conveyor belt alignment, part positioning, and robotic arm movements for precise assembly.
- Quality Control: Measures component dimensions, gap distances, or material thickness in real time to ensure compliance with specifications.
- Equipment Maintenance: Detects wear and tear by monitoring mechanical clearances or structural displacements.
- Warehousing & Logistics: Optimizes storage layouts by measuring shelf spacing or cargo dimensions for efficient space utilization.
Technical Specifications
Accuracy: Fixed within 22m range, with adjustable distance offset (±1mm resolution).
Communication: Isolated RS485 with MODBUS-RTU, address configurable (0–254).
Safety: Requires qualified personnel for installation; supports laser on/off control without affecting measurement.
The KLSA series combines precision, versatility, and robustness, making it an essential tool for enhancing efficiency and reliability in industrial and manufacturing processes.
