HCT402 Manual Hydraulic Lever to Electronic Control Conversion Kit

Next generation. 7-40V (12V/24V direct), ~20 kgf torque, reverse-polarity protection, Soft/Dynamic modes. IP67.

HCT402 is the next-generation evolution of AXI Technology's manual hydraulic lever conversion series. Built on the proven HCT400 platform and validated through full field & performance testing, HCT402 brings wide voltage support (7–40V), reverse-polarity protection, ~20 kgf high torque, and software-driven Soft / Dynamic control modes for professional industrial use.

The high-torque HC402 servo motor applies approximately 20 kgf to the hydraulic lever — enough to drive multiple levers comfortably. Combined with AXI's proprietary XRF encrypted RF protocol, IP67 protection, ±1° PID-based proportional control and a sub-second response time, HCT402 is engineered for demanding outdoor and heavy-duty applications.

Stronger, safer, more precise. HCT402 introduces wide-voltage operation, reverse-feed protection and a dual-mode controller (Soft / Dynamic) — a new generation for manual hydraulic levers.

Highlight Features

Wide Voltage 7–40V
Direct support for 12V and 24V battery systems. Stable lever control even under low-voltage conditions in the field.
Reverse-polarity Protection
If supply leads are wired backwards, the system draws no current and is not damaged. Once corrected, the device boots normally and confirms with an audible beep.
~20 kgf High Torque
The HC402 high-torque servo motor moves even the stiffest manual hydraulic levers and supports multi-lever applications.
Soft / Dynamic Mode
Tie the blue wire to ground for Soft Mode (smooth, controlled motion). Release it to return to Dynamic Mode for sharp, fast response.
Optimised Joystick
Mid-stick area is tuned for fine, millimetric control; end-stick area accelerates the lever to the limits quickly.
Smart Battery & Link Alerts
Audible alert if the remote can't pair with the motor; motion is locked when the battery is critically low. LED + buzzer signal motor disconnects.

3-Stage Calibration

  1. Motor travel range calibration
    Auto-learns the lever's mechanical min/max points, eliminating end-stop pressure and saving energy.
  2. Direction invert
    Flip joystick directions in software to match motor mounting orientation.
  3. Remote pairing
    Bind any remote to a different motor with a guided sequence of joystick gestures and power cycles — settings are stored permanently.

Charging & LED Status

The remote charges over standard USB — cigarette lighter, powerbank, phone adapter. The system rejects control commands while charging, by design.
