Allen-Bradley 1846-1LS9 Precision Limit Switch

The Allen-Bradley 1846-1LS9 Precision Limit Switch—a Micro Switch (Honeywell) electromechanical limit switch—delivers precise position sensing for control and safety circuits in demanding industrial settings. With a 10 A contact rating at 120/240/480 VAC and an SPDT configuration (application dependent), it provides reliable, repeatable switching for machine control and interlock applications. Its die-cast metal housing supports panel- or machine-mount installation and is designed for continuous-duty use in conveyors, machine tools, packaging equipment, material handling systems, cranes, hoists, and automated production machinery where accurate position detection matters. This series is commonly used to replace worn switches and upgrade safety/interlock sensing, with compatible replacements including Honeywell Micro Switch LS1 Series, Azbil 1LS9-J, and Omron WL Series.
