Obstacle Detection for Gate Automation

The most common type of obstacle detection used with gate automation is amperometric sensitivity.

Amperometry in chemistry and biochemistry is detection of ions in a solution based on electric current or changes in electric current.

Obstacle detection is designed to keep users accessing the automated gate safe. It is recommended for commercial installations and anywhere young children are around.


It is possible the system will be able to pick up an obstacle with less than 400 Newton’s of force applied to it. It is usually about 0.7 seconds from when a force is applied to it realising there is an obstacle there and will stop and start to reverse.


So the obstacle detection is activated based on how much force is applied to the gate when the system does not expect it i.e not at the end of the opening or closing phase. The system will learn upon setup the opening and closing cycles, so if you have gate stops in place it will always expect that when it has reached a certain distance in its automation cycle (either the end of the opening phase or the end of the closing phase) it will push up against something solid. So anything that comes into contact with the gate out of those zones will be presumed as an obstacle.


We sell many automation kits which have this obstacle detection feature, such as the Kit MyAster, Kit MyHook, Kit MyShark, Kit Wingo, Kit X-Metro and many more!
