The hlm modular system for individual level solutions

Our modular principle begins when standard solutions are insufficient. At hlm elektronik, we develop and manufacture customized float switches and sensors – individually configured, economically produced, and quickly delivered.
Thanks to our modular system, we combine proven components to create precisely fitting solutions for your application.
Starting from a quantity of 1.

How the modular system works

Instead of prefabricated complete solutions, we rely on flexibly combinable components – individually tailored to your needs:

Mounting type: Internal or external

Housing: Threaded, flanged, or smooth design

Float body: Shape, material & density

Connection type: Cable, plug, or flange connection

Contact form: NO/NC, bistable, or multi-stage

Adjusting/ gripping ring: Fixation methods and connection types selectable

This is how your individual sensor is created

With a manageable number of basic components, we realize a large variety of variants – precisely tailored to your requirements.
