Holding magnet driver
Controllers for solenoids
Our client had trouble with holding solenoids which did not release the object due to residual magnetism. They had to use mechanical pushers for object removal.
The problem has been solved by the development of an electronic solenoid driver which eliminates pushers completely and also reduces the energy consumption of the solenoid. Additionally, a low cost magnetic sensor has been introduced to detect whether or not the object has been attached. The driver has been patented.
