COST-EFFECTIVE ABSOLUTE FEEDBACK OPTION

Description

Exlar announces the Tritex™ II Series electric actuators are now available with a cost-effective absolute feedback option. The compact actuators feature a built-in mechanical converter, eliminating the need for a ball screw or gear reducer mechanism. With the absolute feedback option, Tritex II actuators eliminate the need to perform home cycling—without the high cost and inconvenience of alternative solutions.
 
 To offer proper control and travel within the physical limits of the system, actuator application systems must first identify the position of the actuator upon initialization. This is commonly achieved by a time-consuming and inconvenient homing routine that requires the system to travel on a power up setting until a switch is reached or through a hard stop that establishes the home, or zero position. Alternatively, costly feedback devices such as cumbersome linear transducers or less-reliable multi-turn serial absolute encoders are used.
