Why Choose the Carlo Gavazzi VPB1MNA-1 Photoelectric Liquid Level Sensor?
The Carlo Gavazzi VPB1MNA-1 is a robust photoelectric liquid level sensor designed for point-level detection in tanks and industrial process vessels. Part of the Carlo Gavazzi VP series, it uses modulated infrared light and the refraction principle to detect liquid while keeping the process liquid electrically isolated from the sensor circuitry.
The VPB1MNA-1 combines a durable nickel-plated brass housing with a chemically resistant polysulphone sensing tip. The infrared transmitting and receiving elements are sealed behind the tip, while the integrated amplifier provides a self-contained sensing solution designed for direct mounting through a tank wall.
With a 10–40 V DC supply, NPN NO+NC change-over output, M12 connector and IP67 protection rating, the VPB1MNA-1 is well suited to industrial automation. Its complementary outputs provide flexible control logic, while the connector version enables convenient installation and replacement without a permanently attached sensor cable.

Reliable & Durable Optical Liquid Level Detection
The Carlo Gavazzi VPB1MNA-1 uses modulated infrared light to detect the transition between air and liquid at its polysulphone sensing tip. Changes in optical refraction alter the light received by the sensing element, allowing the integrated amplifier to switch the NPN outputs without requiring a mechanically operated float.
The combination of a nickel-plated brass body, chemically resistant polysulphone tip, IP67 protection and protected solid-state electronics makes the VPB1MNA-1 suitable for demanding industrial level-monitoring duties. The liquid and electrical circuitry remain isolated, while the M12 connector supports efficient installation and servicing.
