Use these mice on cramped workstations in facilities with rough working conditions, such as factory floors, warehouses, and processing plants. Rated NEMA 4X, these mice seal out dirt, dust, and water from washdowns. They’re also designed to endure rough handling, accidental drops, and high vibrations. Unlike standard mice, they withstand more extreme climates, from the high temperatures of heat treatment plants to the low temperatures of cold storage rooms. They take up minimum space by staying fixed on your work surface, unlike conventional mice that need a larger area to move.
