Classic Instruments TDC Sensor
Classic Instruments TDC Sensors: Precision Signal, American-Made Quality
When you invest in a Classic Instruments gauge system, every component in that system matters — including the sensors that feed it data. Classic Instruments' TDC (Top Dead Center) sensors are purpose-engineered to work hand-in-glove with the brand's broader gauge and sending-unit ecosystem, ensuring the accurate, reliable readings that Classic Instruments has built its reputation on for over 45 years.
Classic Instruments takes a philosophy-first approach to every component they produce. They are among the first manufacturers to combine all-electrical instrumentation and microchip technology with high-quality accuracy and vintage styling. That same commitment to precision engineering extends to their sensor lineup. Their innovative approach blends all-electric instrumentation and microchip technology with precision accuracy, and every part is thoroughly tested for reliability to deliver consistent, accurate readings.
Built to Integrate With the Classic Instruments Ecosystem
One of the most important aspects of any TDC or engine-position sensor is compatibility with the rest of your instrumentation. Classic Instruments designs their sensors specifically to eliminate guesswork and fitment headaches. Customers praise their sensing components for excellent fit, functionality, and quality — specifically highlighting perfect compatibility with Classic gauges and efficient performance that eliminates the need for awkward adapters.
Classic Instruments' full sender lineup covers sensors for measuring vehicle speed, coolant temperature, engine oil temperature, oil pressure, and fuel level, along with adapter plates and bushings. The TDC sensor fits within this cohesive ecosystem, giving builders and restorers a single trusted source for all their instrumentation signal needs.
Designed and Assembled in the USA
Every Classic Instruments product — sensors included — is produced at their facility in Boyne City, Michigan. Each and every gauge and component is designed, assembled, and calibrated with pride and quality in Boyne City, Michigan, and their proudly "Made in the USA" products are designed and built for street rods by street rodders. This hands-on, domestic production model means tighter quality control and components that meet the exacting standards of the performance and custom automotive community.
Classic Instruments makes each and every part by hand in their Michigan facility, and each gauge and instrument is assembled and then calibrated to ensure accurate measurements. When a TDC sensor leaves their shop, it has been verified to perform — not just manufactured to a spec sheet.
