Key Features:

Advanced Photoelectric Technology: Utilizes a background suppression (BGS) principle. This technology allows the sensor to precisely detect the presence or absence of a liquid surface at a specific, taught distance, ignoring the background (the far wall of the tank).

Fixed Sensing Distance: This model has a fixed 50 mm sensing range (as indicated by "050" in the part number), optimized for close-range level detection in confined spaces.

Visible Red Light Spot: Emits a highly visible red light (from a laser diode, Class 2) for straightforward and precise alignment during installation and commissioning. The beam spot is clearly visible on the liquid surface.

Teach-In Functionality: Features an intuitive push-button teach-in method. Simply present the sensor to the target (liquid surface) and press the button to set the precise switching point. This eliminates the need for manual calibration and ensures optimal performance.

IO-Link Communication (Smart Sensor): Equipped with IO-Link (version 1.1), making it a smart sensor. This enables:

Parameter setting and device configuration directly from the control system.

Remote monitoring of device status and process data.

Advanced diagnostics and simplified maintenance.

Robust Design & Housing: Built with a stainless steel (V4A / 316L) housing and a PTFE (Teflon) sensing face, making it highly resistant to corrosion, aggressive chemicals, and harsh cleaning processes. This is critical for use in food & beverage, pharmaceutical, and chemical industries.

Electrical Output: Provides a PNP normally open (NO) switching output (configurable to NC via teach-in).

High Ingress Protection Rating: Rated at IP68/IP69K, meaning it is completely dust-tight and can withstand prolonged immersion in water as well as high-pressure, high-temperature wash-downs, making it suitable for hygienic environments.
