Introduction


Balluff offer inductive sensors for all Ex zones. Applications for these wear-free switches range from Zone 2/22, in which an explosive atmosphere rarely occurs (Category 3G/3D), to Zone 0/20, where the greatest explosion hazard is present.

With many sensor styles, Balluff serve a broad range of applications so that you can handle a wide variety of requirements. The comprehensive portfolio includes, for example, pressure rated sensors up to 500 bar or sensors with extended temperature range — all in a variety of housing styles. The appropriate accessories, such as NAMUR switching amplifiers or single-ended cordsets, are also available.
