Our very affordable pocket-sized industrial transmitters are special in that they're the some of the smallest available in the market. As a result of their compactness, the user may more easily negotiate load placement with less fatigue, while not compromising quality and versatility. The 140, 160, and 180 Series Radio Control systems present the user with four, six, or eight pushbuttons, respectively, to choose from. All transmitters are 1-step and are perfect for light-duty, mobile, and industrial equipment.
