The RAM Company rotary solenoid is a pure rotary device utilizing the angles
of a balanced armature within a magnetic field. By eliminating the need for cams or races that convert linear
motion into rotary, as used in other rotary solenoid designs, RAM Company is able to offer distinct design advantages:
• 100 million cycles
• Fast response times
• Controlled torque curves
• High Reliability
• Magnetic latching in one or both directions
• Proportional capabilities
• No linear shaft motion
A significant portion of RAM Company's business consists of various
rotary solenoid design applications. When energized, a rotary solenoid will move to a set degree of rotation.
When de-energized, the solenoid, with the option of a spring or reverse polarity, will return to it's original position.
Land: Sorting applications utilizing rotary devices constitute the largest product lines designed and
manufactured by RAM Company to date. As many as 750,000 rotary actuators have been supplied to customers for diverting
various media. These different types of rotary actuators have been utilized on numerous types of sorting equipment, yielding
very high repeatability and response times while offering the longevity of up to 100,000,000 cycles and beyond. In addition to
sorting applications, RAM Company rotary solenoids are also found in industrial lasers and gun systems for the military. RAM
Company rotary devices are ideal for applications that require high repeatability and peak performance.
Air: RAM Company rotary solenoids are quite commonly used on missile systems as safe-arm
devices. In addition, many rotary solenoids are found in aircraft surveillance and calibration equipment.
Space: RAM Company rotary solenoids are utilized on the International Space Station. In one application,
a rotary solenoid is the device that is used on an outer door lock for unlatching a docking hatch. Another application utilizes a rotary
butterfly valve in the water purification system. Rotary solenoids are utilized on rockets for deploying satellites into orbit.
