TRITEX II™ AC POWERED
ELECTRO-MECHANICAL ACTUATORS
Tritext AC Powered Linear Actuator
Exlar announces the Tritex II™ Series electric actuators, offering 1500 Watt, AC powered operation and digital position control within a single, space-saving housing. These actuators combine a brushless servomotor with either rotary or linear (output) actuation, assembling all elements into a compact, sealed housing for demanding environments. With their built-in mechanical converters, Tritex II actuators eliminate the need for traditional ball screw or gear reducer mechanisms—they incorporate all the required position control and power electronics into the actuator itself, providing a complete system solution. This design additionally eliminates the inconvenience and expense of an external servo amplifier and cables, which are often required with typical servo systems.
The new Tritex II actuators operate from 100-240 VAC, allowing direct connection to factory power sources. Enhanced software features include 16 programmable indexes, linked moves and firmware flash upgrade capability via the actuator's Modbus port. This port, via a RS/485 protocol, allows complete control, programming and monitoring of all aspects of the Tritex II actuator as it performs an application. Planned communications options include Modbus, Ethernet/IP™, HART, Modbus TCP/IP, CANopen, and CAN J1939 protocols.
Tritext AC Powered Rotary Actuator
The Tritex II actuator has ample I/O capability: 8 digital inputs, 4 digital outputs, plus one analog input and output. Feedback choices include analog hall effect (standard), incremental encoder for higher positioning resolution and an absolute feedback option that eliminates the need for performing home routines after power loss. The new Tritex II design offers excellent connectivity with internal terminals accessible through the actuator's removable cover. Tritex II also offers a provision for Imperial or metric threaded ports for cable sealing glands, optional M23/M16 connectors for power and I/O, with an M8 connector for the RS485 port.
Tritex II linear actuators provide the same form factor as hydraulic and pneumatic actuators and provide for simple, clean all-electric retrofits in what were formerly fluid power applications. They are available with many different mounting options (metric or imperial) such as front flange, rear clevis mount, side mount, trunnion mount, extended tie rod, and rear flange.
Tritex II rotary actuators are available in standard IEC metric dimensions. Direct drive units, as well as units with integral planetary gearing, provide compact, powerful solutions for most rotary applications. Custom mounting and options for both rotary and linear actuators are available to meet a wide range of installation requirements.

GREAT IDEAS THAT WORK
Technology Reporting from Exlar
How to Create Nothing – Faster
When it comes to injection molded plastic parts for everyday items such as vacuum cleaners, hearing aids, or blood filters, moldmakers have historically turned to hydraulic cylinders for motion control solutions. Rethinking this tradition— and focusing on the precise, rapid motion necessary in injection molding applications, sheds new light on electro-mechanical actuators with integrated motors, like the Exlar GSX Series, which delivers a longer operation life and saves operators time and money.

Unmanned Vehicles –
DARPA Challenge
The DARPA Urban Challenge allows researchers to create and test an autonomous ground vehicle — a vehicle technology that operates without a human driver or remote control. These vehicles, which have been developed for use in war zones to keep soldiers off the battlefield and out of harm's way, utilize various sensors and positioning systems to determine the characteristics of the surrounding environment. SoftThought Inc., a company participating in the challenge, turned to Exlar for lightweight, durable, and compact actuators and a rotary motor for their SOLO Autonomous Ground vehicle design.
