Electric rotary actuators

Exlar has announced the Tritex II Series electric actuators, offering 1500 W AC powered operation and digital position control within a single, space-saving housing.

The actuators combine a brushless servomotor with a rotary 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 gear reducer mechanisms — they incorporate all the required position control and power electronics into the actuator itself, providing a complete system solution.

The actuators operate from 100-240 VAC, and software features include 16 programmable indexes, linked moves and firmware flash upgrade capability via the actuator’s Modbus port. This port, via a RS485 protocol, allows complete control, programming and monitoring of all aspects of the actuator.

The actuator has eight digital inputs, four digital outputs, plus one analog input and output. Feedback choices include analog Hall effect (standard) and incremental encoder for high positioning resolution. Tritex II 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 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.

Tritex II rotary actuators feature: 90 and 115 mm frame sizes; motor torques to 11.9 Nm; and integrated planetary gearing options in 4:1 to 100:1 ratios, offering torque output to 530.4 Nm.

Maximum speed of the actuators is 1700 rpm, and IP65 sealing is standard.
