The Thompson Electrak Pro electromechanical linear actuators from Danaher Motion target mobile off-highway applications that need compact, low maintenance, robust actuation systems. These electromechanical actuators have a host of features including a electronic load monitoring, low-voltage power switching, programmable limit switches, signal follower input and PWM speed control monitoring. Available with ball or acme screws, these actuators have input voltages of 12 and 24V dc. they hand maximum static loads of 1,500 lb in the acme screw version and 4,000 lb for the ball screw model. The respective dynamic loads are 750 lb and 2,000 lb Maximum stroke for both models is 12 inches and both have been designed for the shortest possible retracted length, allowing used in cramped quarters.
