Configuration Options

Tritex II DC Linear Actuator Configuration Options

AAA = Actuator Type
TDM060 (60 mm) and TDM075 (75 mm) standard capacity actuators – Legacy Product
TDX060 (60 mm) and TDX075 (75 mm) high capacity actuators

BBB = Frame Size
CC = Stroke Length
DD = Screw Lead (linear travel per screw revolution)
E = Connections
F = Mounting
G = Rod End
HH = Feedback Type

III-II = Motor Stator
Motor options are described with a 3-digit code. The first digit calls out the stack length, the second digit designates the rated bus voltage, and the third digit identifies the number of poles. Please refer to the mechanical/electrical specifications for motor torque and actuator rated force.

Mechanical Options              

AR = External Anti-rotate Assembly

This assembly restricts the actuator output rod from rotating when the load is not held by another method. Shorter actuators have a single anti-rotation mechanism; longer lengths have a mechanism on both sides.

L1, L2, L3 = Adjustable External Travel Switch(es)

External travel switches indicate travel to the controller and are adjustable for either the home or end position.

RB = Rear Electric Brake

This is a rear, internal holding brake. The rear brake is spring activated and electrically released.

SR = Splined Main Rod

A ball spline shafting main rod with a ball spline nut that replaces the standard front seal and bushing assembly. This rod restricts rotation without the need for an external mechanism. The rod diameter will be the closest metric equivalent to our standard rod sizes. Since this option is NOT sealed, it is not suitable for environments in which contaminants may enter the actuator.

Note: Adding this option affects the overall length and mounting dimensions.


*  Some options are not available with every configuration. For options or specials not listed above or for extended temperature operation, please consult Exlar Applications Engineering.
