Ametek 2000129B Rotary Limit Switch

AMETEK Gemco 2000129B is a 2000 Series geared rotary limit switch built for end-of-travel and position feedback in industrial equipment. Housed in a blue fibralloy NEMA 12 enclosure, it features a 1/2" input shaft with included woodruff key and keyway and a worm-gear drive with a 150:1 ratio, driving two independently adjustable SPDT switches (two cams) that can be wired NO or NC. The unit provides two electrical circuits with four screw terminals per switch and is UL listed for use with standard controls. Its compact footprint is roughly 4" high by 8" long by 4" deep, and it is rated for operation up to 180°F. Typical applications include conveying, packaging, and other machinery where dual end-of-travel sensing or position feedback is required, using the two cam positions to trigger separate control actions.
