The single-axis PRO-4HA joystick, a noncontacting, Hall-effect proportional output device, has a longer life than its predecessor, the potentiometric PRO-4.
Features of PRO-4H include EMI resistance, 0.5 to 4.5-Vdc proportional output, mechanical interlock, and a variety of amplifiers and PWM circuits. The controller accommodates various handle designs for use on scissor lifts, aerial work platforms, bucket trucks and cranes, and agricultural, mining, and forestry equipment.
