Why Choose the Carlo Gavazzi VPB1MNA Photoelectric Level Sensor?
The Carlo Gavazzi VPB1MNA is a compact photoelectric liquid level sensor designed for point-level detection in tanks, containers and industrial process equipment. It uses modulated infrared light to detect the presence or absence of liquid at the sensing tip, providing electronic level monitoring without a conventional mechanical float.
Part of the Carlo Gavazzi VP series, the VPB1MNA incorporates the optical transmitter, receiver and amplifier within a self-contained sensor assembly. It provides an NPN change-over output (NO+NC), giving both normally open and normally closed switching functions for flexible integration with compatible PLCs, relays and control systems.
The VPB1MNA features a chemically resistant polysulphone sensing construction and a pre-wired cable connection. Its optical operating principle is well suited to industrial applications requiring compact, repeatable liquid presence detection for filling, emptying, alarm and process-control functions.

Reliable Photoelectric Liquid Level Detection
The Carlo Gavazzi VPB1MNA determines liquid presence by monitoring the behaviour of infrared light at its sensing interface. When the optical conditions change as liquid reaches or leaves the sensing point, the integrated electronics change the output state, providing an electrical level signal without relying on a moving float mechanism.
Its NPN NO+NC output gives designers access to both normally open and normally closed switching functions, while the pre-wired cable and compact polysulphone construction support straightforward integration into suitable tanks, process equipment and OEM machinery.
Typical Applications
- Industrial tank and container level detection.
- High- and low-level liquid monitoring.
- Automatic filling and emptying systems.
- Pump and valve control systems.
- Process and production equipment.
- Liquid storage and handling systems.
- Packaging and processing machinery.

Frequently Asked Questions
What is the Carlo Gavazzi VPB1MNA?
The VPB1MNA is a photoelectric liquid level sensor designed for point-level detection using infrared optical sensing technology.
What output does the VPB1MNA provide?
The VPB1MNA provides an NPN change-over output with normally open and normally closed functions (NO+NC).
How does the VPB1MNA detect liquid?
The sensor uses modulated infrared light. A change in the optical conditions at the sensing point when liquid is present or absent causes the electronic output to change state.
What material is used for the VPB1MNA sensing construction?
The VPB1MNA uses polysulphone, providing chemical resistance for use with compatible industrial liquids.
What electrical connection does the VPB1MNA use?
The VPB1MNA is a pre-wired cable version, allowing direct connection to compatible industrial control equipment.
Does the VPB1MNA provide both NO and NC switching?
Yes. Its NPN change-over output provides both normally open and normally closed switching functions.
Does the VPB1MNA require a mechanical float?
No. The VPB1MNA uses photoelectric infrared sensing, so liquid presence is detected without a conventional mechanical float.
