Twist-to-Lock Control with Reliable Position Holding
The Phidix Twist-Lock Push-Pull Control Cable series is engineered for applications requiring secure mechanical
locking of the control position. Through a simple quarter-turn
twist of the T-handle, the cable locks in place, maintaining its
position even in high-vibration environments.
This structure is especially suited for throttle/choke control, PTO
systems, engine shut-off mechanisms, and valve operations in
sectors like heavy-duty trucks, construction machinery,
agricultural vehicles, and marine engines.
Whether you need full cable assemblies or customized knob, core, or
output-end configurations, Phidix offers flexible manufacturing
that meets your specific installation and durability needs.
Key Features
• Twist-to-Lock Mechanism – Locks cable position with a quarter-turn twist, preventing
unintended movement from vibration or shock.
• Secure Manual Holding – Ideal for applications where a fixed actuator position must be
manually maintained.
• Modular Configuration – Available with various shaft sleeves (green/black), knob colors
(black/red), core types (wire rope or standard core), and output
ends (threaded/U-fork).
• Rugged Construction – Designed for demanding industrial and vehicle environments;
vibration-resistant and corrosion-tolerant.
• OEM Ready – Built to support automotive standards such as IATF 16949;
customizable for bulk/serial applications.
Typical Applications
| Application | Function |
| PTO (Power Take-Off) Systems | Lock the position of PTO engagement control |
| Engine Shutdown Cables | Ensure secure disengagement and position hold |
| Manual Throttle/Choke Control | Maintain fixed RPM or startup choke position |
| Valve Positioning | Lock fluid flow or hydraulic valve settings |
| Parking Brake Mechanisms | Prevent rollback in heavy vehicles |
| Remote Control Panels (Cabin/Box) | Lockable input for operator-actuated systems |
Why it matters: In environments with vibration, slope, or
continuous mechanical load, non-locking cables may slip. Twist-lock solutions ensure safety and consistent operation.
