Technical drawing

This miniature float switch with an 8 mm switching tube was specially developed for compact container applications where simple external mounting and reliable switching points are required. The housing and float are made of robust PVC, making them ideal for water-based and mildly chemically contaminated media. The energy-efficient reed technology operates without continuous current and enables precise, long-lasting level detection. Thanks to the G 3/8 external thread, the sensor can be quickly and safely mounted from the outside, offering a clean, tight installation in a variety of applications.
