Key Features
High Accuracy and Resolution: Provides micron-level resolution and high repeat accuracy, enabling precise measurement for critical inspection tasks.

Triangulation Principle: The sensor projects a visible red laser spot onto the target. A receiver in the sensor detects the reflection angle, which changes with distance, allowing for precise calculation of the target's position. This method is effective on a wide variety of surfaces.

Analog and Switching Outputs: Integrates both a high-resolution analog output (e.g., 4-20 mA or 0-10 V) for continuous distance measurement and a programmable switching output (e.g., NPN or PNP) for window comparator functions (e.g., go/no-go detection).

Visible Red Laser Spot: Features a Class 2 laser with a highly visible spot, making alignment and targeting straightforward during setup.

Teach-In Functionality: Allows for easy configuration of measurement ranges and switching points directly via a button on the sensor or through an external teach-in wire, simplifying integration.

Robust Metal Housing: Housed in a rugged, shielded metal casing designed to withstand the electrical noise and mechanical stresses of an industrial environment.

Fixed Cable Connection: This specific model is equipped with a fixed, attached cable for power and signal output.
