Linear actuators with superior ­performance

1st Quarter 2016 Electrical switching & drive systems & components

Thomson’s new Electrak HD electric linear actuator platform with flexible onboard electronics offers superior performance and unmatched environmental protection.

Industry-leading onboard electronics

The culmination of decades of design and application engineering, the Electrak modular control system (EMCS) is the foundation for the best onboard controls currently available and includes optional built-in J1939 CAN bus support. This enhances controllability, eliminates the need for individual standalone controls and simplifies OEM machine design.

The feature-rich modular design for all control and feedback options is simple to use and built within one compact housing, thereby saving space and reducing installation time and total cost.

Electronic trip point calibration ensures consistent overload protection. Constant monitoring of critical parameters, such as end-of-stroke, voltage, current and temperature is standard on all HD actuators. Each HD electric linear actuator is equipped with the Electrak Monitoring Package, which constantly monitors critical parameters and takes appropriate action as needed. Each unit resets automatically when conditions return to normal.

Built-in dynamic braking reduces coast at the end of stroke, improving repeatability, while the optional low-level switching with automatic sleep mode reduces footprint, lowers costs and boosts circuit isolation. Another feature is the optional end-of-stroke indication output for use in interlocks, for example.

Superior performance

Efficient actuator design, including a high quality ball screw, reduces current draw by up to 20%. Higher power up to 10 kN and longer stroke lengths up to 1000 mm enable the Electrak HD to tackle applications outside the range of other electric linear actuators. The higher power opens a new, wider range of hydraulic applications to electric conversion. The efficient actuator design, including a high quality ball screw, reduces current draw by up to 20%.

Additional standard features include integrated manual override, standard anti-rotation actuation and integrated thermal overload protection. A load lock protects against ball nut overload failure and there are flexible front and rear clevis options.

The optional control functions can eliminate the need for external controls, saving on design and installation time, as well as space and installed cost. A generous selection of control configurations can tailor the HD to a wide range of heavy duty applications.

Unrivalled environmental protection Electrak HD is tested to meet and exceed the toughest OEM mechanical and electronic component acceptance tests in the market today, including IP69K (static), IP67 (static) and IP66 (dynamic). It is capable of operating in a wide temperature range from -40 to 85°C and is salt spray tested for 200 hours.
