Industrial 2000-167B Rotary Limit Switch NEMA-7

The Gemco Ametek Patriot Sensors 2000-167B Rotary Limit Switch is a rugged, geared rotary limit switch designed for hazardous locations, housed in a cast aluminum enclosure with a ½" input shaft. It delivers a 250:1 gear ratio via a worm-gear drive, enabling precise rotational sensing for machine-control sequencing. This model provides two DPDT (two-circuit) contact sets driven by two cams, delivering two independent limit signals from a single unit. The 2000-167B is specified for NEMA 7 environments, making it suitable for use in hazardous-area applications such as oil/gas or chemical processing, and it is part of AMETEK’s 2000 Series geared rotary limit switches used in machine tools, handling equipment, and rotary operators where motion is expressed in shaft rotation. The shaft input is ½" and the catalog data note an input shaft turns value of 237, reflecting the turns required to complete a cycle. Typical applications include conveyors, packaging lines, and other industrial machinery requiring reliable rotary-limit feedback in demanding environments.
