Brand: Mercotac
Model: M430C
Product Type: Brushless Mercury Rotary Electrical Connector / Mercury Slip Ring
Condition: Brand New
Lifecycle Status: Active
Product Overview
The Mercotac Model 430C is a 4-conductor, liquid-metal rotary electrical connector designed to transmit both power and sensitive signals across rotating interfaces. Its brushless, mercury-based design ensures virtually no electrical noise (<1mΩ contact resistance), maintenance-free operation, and a long service life.
This model is ideal for heated roller applications requiring connection to sensitive thermocouple signals while simultaneously powering the heating elements. It is also a versatile solution for packaging machinery, robotics, medical equipment, cable reels, and semiconductor production equipment.
