1 Proportional Solenoids The following electromagnets are examples for proportional solenoids realized in series. Magnetbau Schramme developments are customer-specific. If you are searching for the right electromagnet or solenoid for your series project, simply contact us for the perfect solution. Our team will help you - guaranteed. Please note that we do not have „ex stock“ standard products, and can therefore only process inquiries for series.

2 proportional solenoids, electromagnet, magnetbau-schramme_en.pdf © Magnetbau Schramme GmbH & Co. KG Version Proportional solenoids are DC linear solenoids with analog path/current and force/current characteristic. They are used as proportional actuators in hydraulic control chains and open control loops for actuation of pressure and flow control valves, as well as for proportional directional control valves. The units are pressure-tight and equipped with a manual emergency override, which corresponds with the safety regulations. They are manufactured and tested according to VDE 0580...
