Honeywell LKS310-25 (A5B-15S7.1) actuator

The Honeywell Conectron LKS310-25 (A5B-15S7.1) servomotor is designed for multistage or modulating oil and gas burners with a fully closed position. This Conectron 78-LKS310-25U servomotor is equipped with an output shaft for an asynchronous motor and a backlash-free cam shaft controlled by a gearbox. The camshaft controls the limit and auxiliary switches, which can be steplessly adjusted using a special camdisc disc. Manually adjustable cams and spindle-driven cams are available for this purpose.
