Information About WL45-R650
The WL45-R650 is part of SICK’s WL45 series of compact photoelectric sensors engineered for long-range and reliable object detection. It operates as a polarized retro-reflective sensor with a dual-lens optical system that enables detection even at minimal distances to the reflector. The use of visible red light allows straightforward alignment during installation and maintenance. A heated lens is integrated to ensure consistent sensing performance in environments prone to condensation or temperature fluctuations.
Key Features
- Polarized Reflex Operating Principle: Enables reliable object detection while suppressing false reflections from shiny or reflective surfaces.
- Dual-Lens Optical System: Supports stable sensing performance even at short distances to the reflector while maintaining long-range capability.
- Long Sensing Range: Detects objects reliably across distances from 1 m up to 45 m, supporting flexible installation layouts.
- Heated Lens Design: Prevents condensation and maintains optical clarity in cold or humid operating environments.
- Wide Supply Voltage Range: Operates from 20 to 250 V AC/DC, allowing integration into diverse industrial power systems.
- UC SPDT Output: Provides flexible switching output compatible with both AC and DC control circuits.
- Compact Rectangular Housing: Combines robust industrial construction with a space-efficient form factor for machine integration.
The WL45-R650 delivers the reliability and precision required for long-range object detection in demanding industrial automation and material handling applications.
