Individual float switches

Reed float switches are potential-free and are based on a very simple yet tried-and-tested technology. Up to six limit levels can be monitored. Float switches are always designed and produced in line with customer requirements, are easy to install and do not require any programming.

Our float switches are based on the tried-and-tested Reed contact-magnet principle, which guarantees reliable and long-lasting functionality. The only moveable component within the sensor is the float itself.

  • Customer-specific production with no minimum order quantities
