Honeywell Servomotor A5-5S4 LKS160-39

This 230 V servomotor is intended for controlling the air/fuel linkage of multistage or modulating liquid-fuel burners. It has a rated torque of 2.5 Nm and consumes 4 W. The drive is a reversible synchronous motor connected via a maintenance-free cylindrical gear transmission, and the drive shaft is made of steel. Electrical connection is via terminal blocks, the position is shown on a scale, and the enclosure is protected to IP44. The unit is safety class 2 and complies with EU directives 73/23/EU and 93/68/EU. It measures 13 x 6.2 x 14.5 cm and weighs 600 g.

Servomotors of this type are selected by comparing supply voltage, rated torque, mounting dimensions, and the linkage interface with the burner manufacturer's specification. Units are usually attached from the inside using M5 threaded through-holes, and the cam switching points are set without steps. Before ordering, check the required operating angle and verify that the shaft coupling or lever matches the valve or damper spindle. Such servomotors may be installed in any position.
