Product details

Electric Joystick Assembly U / W / T

1. Product Overview

Electric Joystick Assembly U/W/T is an electronic proportional control handle widely used on modern intelligent crawler excavators. It converts manual operation displacement into standard electrical signals and transmits signals to the vehicle controller. The controller outputs corresponding instructions to drive proportional valves, so as to control the movement of boom, arm, bucket, slewing and travelling devices.

Models U, W and T adopt different internal sensor structures, wiring definitions and signal output logic, designed to match different brands and types of electronically controlled excavators. High-quality interchange aftermarket assemblies can be used for equipment maintenance and renovation.

Model Definition

- Electric Joystick Assembly U: Matches specific control logic for designated excavator working functions

- Electric Joystick Assembly W: Independent signal configuration, corresponding to another group of action control program

- Electric Joystick Assembly T: Special sensor and wiring layout for other machine models

2. Main Technical Parameters

Item Specification

Product Name Electric Joystick Assembly U / W / T

Control Mode Electronic proportional control

Power Supply 12VDC / 24VDC (depending on machine configuration)

Signal Output CAN bus signal / Voltage proportional signal

Operating Temperature -20℃ ~ +75℃

Protection Grade IP65

Installation Type Console mounting

Core Component Non-contact Hall effect sensor

3. Working Principle

When the operator pushes or swings the joystick lever, the built-in Hall sensor detects the direction and amplitude of the lever movement and converts mechanical motion into continuous variable electronic signals.

Signals are sent to the excavator ECU. After data processing, the ECU sends control signals to hydraulic proportional valves to adjust the oil flow direction and flow rate of the hydraulic system, realizing the smooth operation of each actuator.

When external operating force is removed, the built-in return spring automatically resets the joystick to neutral position. The sensor outputs neutral signal, and all machine movements stop.

4. Core Advantages

1. Non-contact Hall sensor structure, no mechanical wear, long service life and stable signal output.

2. High control precision, smooth proportional adjustment and comfortable operating feel.

3. Excellent waterproof and dustproof performance, adaptable to harsh outdoor construction conditions.

4. Low energy consumption, strong anti-interference capability, effectively avoid signal drift.

5. Wiring harness, mounting hole dimension and installation interface consistent with original parts, direct plug-and-play replacement.

6. Cost-effective aftermarket spare parts with short delivery cycle for machinery overhaul.

5. Application Range

Suitable for electronically controlled crawler excavators of multiple mainstream brands.

Electric Joystick U, W, T are configured with independent signal programs, separately matched for boom, arm, bucket and slewing control functions.

Fit for excavators equipped with matching electronic control system.
