High-Performance Triaxial Connectors for Precision Signal Transmission
INTE-AUTO provides push-pull triaxial connectors designed for low-noise and high-integrity signal transmission in precision measurement, testing, sensing, and specialized electronic equipment.
Triaxial Connectors for Low-Noise Signal Transmission
INTE-AUTO triaxial connectors feature three concentric conductive layers, providing additional shielding and signal isolation compared with standard coaxial connectors. This construction makes them suitable for applications requiring low-noise, low-current, and high-impedance signal transmission.
Combined with a push-pull self-latching mechanism, our triaxial connectors provide quick, secure, and convenient connections for precision test instruments, semiconductor equipment, sensors, and laboratory measurement systems.

Triaxial Connectors – The Ultimate FAQ Guide
A triaxial connector uses three concentric conductive layers instead of the two conductors found in a standard coaxial connector. The additional conductive layer can be used as a guard or additional shield in sensitive measurement systems.
A coaxial connector has a center conductor and outer shield, while a triaxial connector adds another conductive layer between them. This additional layer provides greater isolation and is particularly useful in low-current, high-impedance, and low-noise measurement applications.
Triaxial connectors are commonly selected when the application requires very low current measurement, high impedance, reduced leakage, enhanced shielding, or improved isolation from electrical noise.
Consider the equipment interface, electrical requirements, triaxial cable type, connector size, installation space, plug or receptacle configuration, and operating environment.
The connector must be compatible with the cable dimensions and conductor structure. Providing the triaxial cable model, dimensions, or datasheet helps ensure the correct connector and termination method are selected.
Depending on the series, straight plugs, right-angle plugs, cable-mounted receptacles, and panel-mounted receptacles can be supplied for different equipment and cable routing requirements.
The plug locks automatically when fully inserted into the mating receptacle. Pulling the outer release sleeve disengages the locking mechanism for quick and convenient disconnection.
Yes. Triaxial connections are widely used in sensitive low-current measurement systems because the additional guard conductor can help reduce leakage effects and improve measurement accuracy when the complete system is properly designed.
