Abstract: An ingress control system utilizes magnetic detection to determine whether the ingress control system is either allowing or disallowing ingress into a controlled area. The ingress control system includes a latch pin that is movably disposed within a latch assembly in the presence of a magnetic field. The magnetic field is created by a plurality of magnets disposed at non-zero angles relative to each other and the latch pin and latch assembly are introduced as magnetic poles disposed within the magnetic field. A magnetic sensor detects the presence of the latch pin within a receiving channel of the latch assembly by measuring a magnetic field magnitude above a threshold value. The magnetic sensor detects the absence of the latch pin within a receiving channel of the latch assembly by measuring a magnetic field magnitude below the threshold value.
