The AMETEK Gemco Electric 2000-166B functions as a 2000 rotary limit switch maximum speed. It is a rotary cam-operated limit switch or switch-position controller from AMETEK Gemco Electric, used to trigger electrical contacts at defined points in a machine's rotary or linear cycle.

Gemco Electric's cam limit switches use a rotating shaft fitted with adjustable cams that trip individual switch contacts at set positions in the machine cycle, a design widely used for sequencing, end-of-travel detection, and interlocking on industrial machinery. Many models in this family, including adjustable and programmable variants, allow the number of cams, contact arrangement, and trip points to be configured to the application. AMETEK supports parts such as the 2000-166B as part of a broader catalog of industrial instrumentation and electromechanical components, sourced to match the original fit, form, and function of the unit being replaced.

Key Features and Specifications:

• 1000 RPM worm gear type standard two cam DPDT
• NEMA 7
• Manufactured by AMETEK Gemco Electric

The 2000-166B is generally specified as a replacement for an existing Gemco rotary limit switch, matched by cam configuration, contact arrangement, and shaft style to the equipment it controls. This type of switch is common in packaging, material handling, and process machinery where precise end-of-travel or sequencing signals are required.
