Camcon Binary Actuator

A Camcon binary actuator is an electronically controlled electromagnetic actuator that switches between two stable positions and, unlike a conventional solenoid, draws power only while it is switching rather than needing a constant current to hold its position. An electromagnet polarizes a rod held between two magnetic poles, and energizing the electromagnet pulls the rod charge toward one pole or the other, pivoting the rod at its midpoint to open or close a valve, while springs store energy to help the rod move between its two states and so cut the power needed to switch it. Its low power draw suits it to automating gas lift equipment in oil and gas extraction, to controlling anti-lock braking systems, parking brakes and engine valves in vehicles, and to precise oxygen flow control and other functions in implantable medical devices, prosthetics and drug dispensing equipment. It was originally developed by Wladyslaw Wygnanski for aircraft noise reduction and spacecraft use before being commercialized by Camcon for wider industrial and medical application.
