I. Product Overview

This CNC resistor component is a precision electrical special insulation conductive connector, featuring a metal terminal that is integrally turned and shaped on a CNC centerless grinder with multi-level limiting steps. It is assembled with an alumina ceramic insulating tube in the middle, physically isolating the two pole conductive structures to achieve both pressure resistance insulation and stable conductivity. The assembly is tightly combined, shock-resistant, and not easily loose, suitable for high-voltage and precision signal working conditions.
Metal materials such as brass, Kovar alloy, and stainless steel can be processed for conductive terminals, with dimensions, pin diameter, and ceramic length customizable according to customer drawings or physical samples; both small batch trials and large volume long-term supply can be undertaken, with production inspected throughout the process according to the ISO9001 quality management system.
