1980 Rotating Cam Limit Switch

 
DESCRIPTION
 
The Series 1980 Micro-Adjust Rotating Cam Limit Switch is a pilot device used for heavy duty material handling mechanisms, mechanical presses, packaging machines, rotary tables, and in many other applications where repetitive and sequential operations are required in control circuitry. When motion is expressed in shaft rotation, either thru a roller chain, gear train, or directly, the Rotating Cam Limit Switch makes it possible to open or close independent circuits at any desired angular positions. The Series 1980 is available in NEMA 1, NEMA 4 & 5, NEMA 7, NEMA 9, and NEMA 12 enclosures. The units can be ordered with 2 to 40 circuits.
