Rhomberg Capacitive proximity sensors, used to detect most materials, especially liquids, plastics and grains, are available in Namur, DC, NPN & PNP and AC formats. They are extremely robust and conform to international standards, making them suitable as replacements for most other brands. (Available with 2 metre moulded leads as standard or a plug as an option).
