HJ50 series
Grip-type single-axis operating Joystick
Product Features
Heavy-duty industrial electric control handle, specially designed and used for construction machinery industry.
Long-life potentiometer angular displacement detection method.
Both spring return and friction positioning are considered.
A mechanical lock can be carried in the middle position.
A variety of different types of handles are available for selection. At the same time, the number and position of the buttons also have different configurations.
The PWM output directly drives the proportional solenoid valve. And set the starting current, maximum current and PWM frequency according to different proportion solenoid valves.
Optional CAN bus output.
Application range
This series of products are mainly used in cranes, loaders, forklifts, excavators, aerial work vehicles, tractors, harvesters, etc.
