Output options: Transistor NPN/PNP, NO or NC switching
Output states:
VP01/03: Output OFF when sensor is in liquid
VP02/04: Output ON when sensor is in liquid
No electrical or thermal connection between liquid and electrical circuit
LED indicator for output ON status
Power supply range: 10 to 40 VDC
Self-contained transmitter and receiver in a solid plastic housing
Suitable for mounting into container walls
Available in Polysulfone and Polyamide 12 housings, resistant to acids, bases, and solvents

Dimensions and Operation
The sensor utilizes infrared light emitted from a Ga-As diode, with a conical tip forming a 90ºC angle acting as a prism. When the sensor tip is immersed in a liquid with a different refractive index from air, the internal reflection is disrupted, signaling the liquid presence. The sensor is capable of operating in oils, waste water, and aqueous solutions such as beer, wine, and alcohol without additional accessories.
Installation and Usage
The sensor is designed for easy mounting into container walls, with self-contained transmitter and receiver components. Proper installation ensures reliable liquid level detection in various industrial applications.

Unfortunately I havent tested the 5G, Only difficult part was connecting antennas. But everything is good, by default it runs on Qualcom's QMI mode, Had to switch to MBIM and it works good with Windows. Planning to run with OpenWRT soon.
