Key Features & Strengths:

Extreme Long-Range Capability: Designed for the most demanding distance applications, offering an exceptional sensing range of up to 250 meters (with appropriate SICK reflector). This outstanding performance makes it ideal for large-scale industrial automation and severe outdoor applications.

Advanced Polarization Filter Technology: Incorporates a high-performance polarization filter that enables reliable detection of shiny, reflective surfaces (including vehicles, metal containers, and glass) while completely eliminating false signals from non-target reflective objects.

Superior Excess Gain: Generates an extremely powerful light signal that maintains stable operation under adverse conditions including dense fog, heavy dust, rain, snow, and partially contaminated reflectors.

Maximum Ambient Light Immunity: Utilizes precisely modulated infrared light (880 nm) with advanced filtering technology to reject interference from all ambient light sources, including direct sunlight and high-intensity artificial lighting.

Ultra-Robust Metal Construction: Features a heavy-duty, nickel-plated brass housing that provides exceptional resistance to mechanical impact, corrosive chemicals, oils, and extreme environmental conditions.

Highest Protection Rating: Rated IP67 for complete protection against dust ingress and capability to withstand temporary immersion in water.

Short-Circuit Protected Output (M): The "M" in the model number indicates a short-circuit protected output configuration, enhancing system reliability and preventing damage from wiring errors.

Industrial-Grade Connection: Features a fixed cable connection with robust, industrial-grade cabling for maximum reliability in demanding applications.
