Mettler Electronics 3981 Special Coaxial Cable for Auto Therm Drum Applicator 3980

Mettler Electronics 3981 Special Coaxial Cable for Auto Therm Drum Applicator 3980 (ME 391)

The Mettler Electronics Professional Special Coaxial Cable is a high-frequency, medical-grade transmission line engineered specifically for the Auto*Therm 390 and 391 Shortwave Diathermy systems. Precision-built to deliver raw radiofrequency (RF) power safely from the main generator chassis to the specialized Model 3980 Inductive Drum Applicator, this heavy-duty cable is a critical system component for deep-tissue thermal therapy protocols.

Because shortwave diathermy operates at an international standard frequency of 27.12 MHz, standard wires cannot be used without causing severe power leakage, dangerous overheating, or radio interference. This specialized cable utilizes a multi-layered coaxial design, featuring a dense, highly conductive copper center core wrapped in thick, low-loss dielectric insulation. This core is surrounded by an ultra-tight silvered or tinned copper braided shield that stops RF leakage and ensures all energy reaches the drum applicator. The entire assembly is sealed inside a rugged, heavy-wall medical polymer outer jacket that stays flexible during positioning while resisting kinking, sweat, and hospital-grade sanitizing wipes. Precision-terminated with custom, high-voltage connectors, it guarantees a low-resistance, arcless mechanical connection that keeps clinical therapy environments safe and effective.

Features:

• Optimized for 27.12 MHz Frequencies Engineered specifically to match the characteristic impedance and high power requirements of Mettler shortwave diathermy units.
• Flawless Multi-Shield RF Protection Features a high-density braided metal shield that prevents electromagnetic leaks, protecting surrounding medical equipment from interference.
• Heavy-Wall Dielectric Insulation Built with a specialized internal insulation barrier that stops high-voltage arcing and keeps the cable surface cool to the touch during long sessions.
• Heavy-Duty Molded Terminations Equipped with heavy, injection-molded strain-relief boots at both connection points to prevent internal wire breakage from continuous clinical positioning.
• Direct Drum Applicator 3980 Interface Provides the exact physical connection and electrical characteristics required to link the Auto*Therm generator to the Model 3980 inductive treatment head.
