Honeywell LKS131-03 (B2-5S3) actuator

The Conectron LKS131-03 (B2-5S3) servomotors are designed for installation on multistage or modulating diesel burners in a fully closed position.

Design and operating principle of the Conectron 78-LKS131-03U servo motor

The synchronous motor drives the output shaft and camshaft without backlash through a gear reducer. The camshaft drives the limit switches and auxiliary switches. The position at which one of the limit or auxiliary switches is triggered can be smoothly adjusted within the operating range using the appropriate cam disc. There are spindle-driven cams that can be adjusted with a screwdriver.
