Maximize detection range and minimize operational friction with the industrial-grade CNTD CM-1703 Long Roller Lever Micro Switch. Built into a heavy-duty structural layout, this horizontal limit switch features an extended hinge arm paired with a rolling wheel designed to reduce physical wear against passing mechanical cams, sliding door brackets, or moving machine targets. The extended lever configuration lowers the physical activation threshold, enabling highly sensitive position tracking across automated conveyor systems, packaging machines, and elevators.
The outer frame is molded with a high-insulation phenolic compound that shrugs off extreme workshop grease, ambient impacts, and high operating temperatures. Internally, the single pole double throw (SPDT) 1NO+1NC snap-action block relies on premium silver alloy contacts to enforce an ultra-low contact resistance (≤15mΩ), keeping your high-load industrial connections stable and safe from electrical arcing.
