vp23em – infrared probe,10-40vdc,npn,nc
Carlo Gavazzi VP23EM infrared optical liquid level sensor with NPN normally closed output and 10–40 V DC supply for industrial liquid detection applications.
Why Choose the Carlo Gavazzi VP23EM Infrared Liquid Level Sensor?
The Carlo Gavazzi VP23EM is a compact and reliable infrared optical liquid level sensor designed for accurate point-level detection in industrial tanks, containers and process equipment. As part of the Carlo Gavazzi VP series optical level sensors, it provides dependable liquid presence detection using infrared technology with a solid-state switching output.
The VP23EM uses an infrared transmitter and receiver integrated into the sensing element to detect changes caused by the presence of liquid. This non-mechanical sensing method provides fast and repeatable operation while reducing maintenance requirements compared with float-based level switches. The sensor is housed in a durable industrial body designed for reliable use in automation environments.
With a 10–40 V DC supply and an NPN normally closed (NC) output, the VP23EM is suitable for direct connection to compatible PLC inputs and industrial control systems. Its compact design makes it ideal for liquid monitoring applications where reliable switching and easy integration are required.
