Pull-Only Rotary Control Cable – Phidix Non-Locking Series

This page provides the official overview for Phidix's industrial-grade non-locking rotary control cables.
For customization options or stainless steel configurations, please visit our Rotary Cable Customization Page.


What Is a Rotary Control Cable?

Phidix’s rotary control cable converts rotational input (typically up to 270°) into linear motion, enabling remote actuation of mechanical systems—without the complexity of electronics or hydraulics.
This cable is non-locking, meaning it returns freely without ratcheting or detents. It’s ideal for manual HVAC controls, heater valves, dampers, marine shut-offs, and other applications where smooth, push-pull motion is required.

Core Working Principle: 270° Turn = 1.5" Linear Travel

Internally, the cable features a flexible spiral-wound inner core housed within a reinforced conduit. The rotary handle turns an input shaft (CW or CCW), driving the internal wire to create up to 1.5 inches of linear stroke at the output.
A simplified schematic:

This design ensures tight transmission, minimal backlash, and precise movement for systems requiring remote yet mechanical control.

Why Choose Mechanical Rotary Over Electronic Actuation?

Feature Mechanical Rotary Cable Electronic Actuator
Wiring complexity None Requires wiring & power
Failure tolerance Manual override always possible May require diagnostic tools
Environment resistance Tolerates dust, vibration, moisture Often needs enclosures
Maintenance Simple replacement May require service technician


Phidix rotary cables are ideal for rugged, space-limited environments where simplicity and reliability matter more than automation.

Frequently Asked Questions

Q: Is this cable reversible?
Yes. It can be configured for CW or CCW input rotation.
Q: Can the cable be mounted in confined dashboards?
Absolutely. Its flexible housing and threaded shaft make it easy to panel-mount in tight enclosures.
Q: What’s the minimum order quantity?
We offer both low-volume prototypes and OEM-level batch runs. Contact us for details.
Q: Can I request longer travel stroke or dual-end actuation?
Those are available under custom configurations. See customization page for details.
