J.R. Merritt Controls’ single axis, Hall-effect joystick is derived from the company’s rugged PRO-4 potentiometric joystick. It offers the same durable mechanics as the PRO-4; however, the PRO-4H joystick is enhanced with the improved lifecycle of a noncontacting Hall-effect proportional output device. Suitable for use on scissor lifts, aerial work platforms, bucket trucks and cranes, as well as agricultural, mining, and forestry equipment, the PRO-4H accommodates various handle designs. Features of the PRO-4H include heavy-duty mechanical construction, resistance to EMI, and standard 0.5 to 4.5-V dc proportional output. Optional features include mechanical interlock and a variety of amplifiers and PWM circuits.
