Key Features & Strengths:

Exceptional Long Range: Designed for long-distance applications, offering a substantial sensing range of up to 100 meters (with a suitable SICK reflector). This makes it ideal for large-scale automation and outdoor applications.

Polarization Filter (Key Feature): This model is equipped with a polarization filter. This is a critical feature that allows the sensor to reliably detect shiny, reflective objects (like metal packaging, vehicles, or glass). The filter ensures the sensor only recognizes the light returned from its specific corner-cube reflector, preventing false signals from glossy target objects.

High Excess Gain: Provides a powerful light signal, ensuring stable operation even in adverse conditions such as light fog, dust, or rain, and with partially dirty reflectors.

High Immunity to Ambient Light: Uses modulated infrared light (880 nm), which allows it to effectively filter out interference from ambient light sources like sunlight or factory lighting.

Robust Metal Housing: Housed in a heavy-duty, nickel-plated brass body. This construction provides excellent resistance to mechanical impact, chemicals, oils, and extreme environmental conditions.

High Protection Rating: Features an IP67 protection rating, meaning it is completely protected against dust and can withstand temporary immersion in water.

PNP Output (P): The "P" in the model number indicates a PNP (sourcing) output configuration.

Fixed Cable Connection (2): The "2" prefix indicates a 2-meter fixed cable for a secure and reliable connection.
