Key Features & Strengths:

Compact and Robust Cylindrical Design: The M18 x 1 mm threaded metal housing allows for easy mounting via a standard locknut, providing a secure and stable installation. The robust construction ensures durability in demanding environments.

Through-Beam Sensing Principle (V): The "V" in the model number indicates this is a Through-Beam sensor. This system consists of two separate units: a transmitter (emitter) and a receiver. It offers the highest reliability and longest range, as it detects an object when it interrupts the light beam between the two units. It is immune to the color, reflectivity, or surface finish of the target object.

Long Sensing Range: The F100 suffix indicates a sensing range of up to 10 meters (1000 cm) between the sender and receiver. This long range provides great flexibility in machine design.

NPN Output (N): The first "N" denotes an NPN output configuration. This is a sinking output, commonly used with PLCs that require this type of input.

Fixed Cable Connection (2M): The "2M" at the end signifies a 2-meter fixed cable for a reliable and direct connection to the power supply and control system, eliminating the need for separate connectors.

Environmental Robustness: Typically features a high IP67 protection rating, making it resistant to dust and capable of withstanding temporary immersion in water, ideal for harsh industrial settings.

Modulated Infrared Light: Uses modulated infrared light for high immunity to ambient light interference from factory lighting or sunlight.
