Detector with capacitance sensor for detecting object being caught by door

A detector for detecting an object being caught by a door, said detector comprising:

• detection electrodes;
• an insulating material insulating said detection electrodes from each other;
• a main body provided on an open end part of said door, said main body containing said detection electrodes and said insulating material;
• a sensor circuit which, together with said main body, forms a capacitance sensor having specified directionality;
• and
• means for grounding said door;
• wherein said main body includes a detection surface defined by said directionality and said detector further comprised means for grounding said door.
