Information About VL18-4N3240
The VL18-4N3240 is part of SICK’s VL18 series of photoelectric sensors, designed for precise retroreflective detection with high resistance to ambient light and reflective backgrounds. It operates with a dedicated reflector and includes a polarizing filter to prevent false switching from shiny surfaces. Sensitivity is adjustable via a 270° potentiometer, enabling fine tuning for different applications. The sensor’s metal housing, IP67 rating, and comprehensive circuit protections make it suitable for continuous industrial use.
Key Features:
- Retroreflective Photoelectric Principle: Detects objects using reflected light from a dedicated reflector.
- Polarized Optics: Minimizes false detection from reflective or glossy surfaces.
- Extended Detection Range: Supports sensing distances from 0.05 m up to 3.7 m.
- Visible Red LED Light Source: Allows easy alignment and stable optical performance.
- Adjustable Sensitivity: 270° potentiometer enables precise detection tuning.
- Light/Dark Switching Selectable: Configurable logic for flexible control integration.
- NPN Switching Output: Compatible with standard PLC and industrial control inputs.
- Robust M18 Cylindrical Housing: Metal construction for durability in harsh environments.
- High Environmental Protection: IP67 enclosure rating for dust and moisture resistance.
- Integrated Circuit Protection: Includes reverse polarity and overload protection.
The VL18-4N3240 delivers the reliability and precision required for industrial retroreflective photoelectric sensing applications.
