Key Features & Strengths:

Long-Range Detection: Designed for extended distance applications, offering a substantial sensing range of up to 70 meters (with a suitable SICK reflector). This makes it suitable for medium to large-scale automation applications.

Polarization Filter (Standard Feature): Equipped with a polarization filter that ensures reliable detection of shiny, reflective objects (such as metal surfaces, vehicles, or glass) without false triggering. The filter allows the sensor to distinguish between its dedicated reflector and other reflective surfaces.

High Excess Gain: Provides a strong light signal that maintains stable operation in challenging conditions, including light fog, dust, or rain, and with partially obscured reflectors.

Excellent Ambient Light Immunity: Utilizes modulated infrared light (880 nm) to effectively filter out interference from ambient light sources, including sunlight and industrial lighting.

Durable Metal Housing: Housed in a nickel-plated brass body that offers strong resistance to mechanical impact, chemicals, oils, and harsh environmental conditions.

High Protection Rating: Features an IP67 protection rating, ensuring complete protection against dust ingress and capability to 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 secure and reliable connection.
