Why Choose the Carlo Gavazzi VPB1MPA-1 Photoelectric Level Sensor?
The Carlo Gavazzi VPB1MPA-1 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 changes at the sensing tip, providing electronic liquid detection without the moving components associated with conventional float switches.
Part of the Carlo Gavazzi VP series, the VPB1MPA-1 provides a PNP change-over output (NO+NC) with light/dark switching and operates from a wide 10–40 V DC supply. Its M12 connector provides a convenient detachable electrical interface for integration with compatible PLCs, relays and industrial control equipment.
The VPB1MPA-1 combines a robust nickel-plated brass housing with a chemically resistant polysulphone sensing tip. With IP67 protection, a G3/8-inch threaded mounting format and pressure capability up to 10 bar at +60 °C, it is engineered for dependable industrial liquid-level monitoring.

Reliable Modulated Infrared Liquid Detection
The Carlo Gavazzi VPB1MPA-1 uses infrared optical sensing to determine whether liquid is present at its sensing point. Separate transmitting and receiving elements are incorporated behind the sensing tip, and changes in the optical conditions caused by liquid are processed by the integrated amplifier to provide a clear electronic switching signal.
The PNP NO+NC change-over output provides both normally open and normally closed switching functions, while the M12 connector enables use with compatible detachable connection cables. Combined with its nickel-plated brass body, polysulphone tip and IP67 protection, this makes the VPB1MPA-1 well suited to automated filling, emptying, alarm and process-monitoring systems.
Typical Applications
- Industrial tank and container level detection.
- High- and low-level liquid monitoring.
- Automatic filling and emptying systems.
- Pump and valve control applications.
- Process and production equipment.
- Liquid storage and transfer systems.
- Packaging and processing machinery.
- OEM industrial automation equipment.
