a) Inductive Proximity Sensors which have the most economical and popular type E2A series in cylindrical shape with various sizes from 4 diameter to M30. Square type sensors have the series TL-X.

b) Capacitive Proximity Sensors have the most popular series E2K series which are used for various applications including sensing of level for liquid inside tanks, etc.

c) Displacement Sensors include the series E2CD used for positioning and discriminating objects which assures high precision repeatability and a minimal temperature drift.
