2.0 SYSTEM CONFIGURATION
2.1 TRITEX TTX SERIES ACTUATOR
Tritex TTX Series actuators provide a robust solution for long-
life, continuous-duty applications even when environmental
contaminants are an issue. In most rotary-to-linear devices,
critical mechanisms are exposed to the environment and must
be frequently inspected, cleaned and lubricated. In contrast,
Tritex TTX Series actuators are designed with all converting
components mounted within sealed motor housings. With a
simple bushing and seal on the smooth extending rod, abrasive
particles or other contaminants are prevented from reaching
the actuator’s critical mechanisms. As a result, actuator life
can exceed that of a ball screw actuator by 15 times, even in
high-speed, high-force applications. In addition, the Tritex TTX
Series has an on-board amplifier with control software and
firmware available from Exlar.
2.2 OPTIONS
2.2.1 Internal Holding Brake
Many applications require the addition of a holding brake. The
Exlar internal holding brake is engaged by a permanent magnet.
The mechanical advantage of the roller screw allows the holding
brake to prevent the output rod from back driving the load. The
holding capacity of the brake is sufficient to hold the rated force
of the actuator.
2.2.2 Anti-Rotation Assembly
The unique design of Tritex TTX Series actuators helps simplify
actuator setup by allowing the user to rotate the extending
rod and thread it in and out of the actuator for mechanical
attachment or system testing. In most applications, the load
is coupled to linear bearings or some other support device,
preventing rotation during operation. To ensure proper linear
motion in applications in which the rod is free to rotate, an Anti-
Rotate Assembly is required to prevent the rod from rotating.
2.2.3 External Limit Switch
A Tritex TTX Series actuator equipped with the anti-rotate and
limit switch options can accommodate multiple limit switches
for use as end-of-travel limit switches or home position sensors
positioned outside the low-profile extruded channel housing.
