The HIT-NOT® proximity alarm sensor is designed for industries using mobile equipment, like warehouses, manufacturing, ports, and others where equipment and pedestrians work in close proximity. Unlike RFID, HIT-NOT® reads and warns through walls, racks, containers and other blind corner obstructions with audible and visual alerts to both the equipment driver and the pedestrian. The Personal Alarm Device (PAD) is worn by the pedestrian and contains elements that sense the magnetic field from the Magnetic Field Generator mounted on the mobile equipment. When magnetic fields are detected, warnings are given to the pedestrian and vehicle operator. The magnetic field is divided into two zones: Warning Zone and Danger Zone.
