products / proportional solenoids

Proportional Solenoids are linear actuators with a force proportional to the current in a limited range. With the addition of a return spring in your application you can make the proportional solenoid into a positioning device, where the position is depending on the input current to the coil.

Proportional Solenoids have two ranges of stroke; the control stroke where the plunger position is dependent on the applied current, and the approach stroke where force is dependent on stroke position. Most applications use only the control stroke.

Proportional solenoids are used in Hydralic control systems, tension control, textile systems force control in robotic systems, valve applications, etc.

The most important characteristics of our Proportional Solenoids are:

• stroke up to 7mm (control stroke plus approach stroke)
• force up to 80N
• high life time, very robust design
• dynamic response
• high energy density
• position control against external spring
