PaceMaker™ Timing Products

Timing is Everything

Improve the accuracy and efficiency of your sensing position and timing applications with new PaceMaker™ timing products from A.J. Rose. PaceMaker™ represents a technically advanced patented innovation for timing requirements of various applications. Employing advanced processing capabilities, engineered solutions are provided for your engine timing, ABS, transmission or general encoding needs.


PaceMaker™ components are available in various configurations to suit your requirements including: e-coated, 1008 carbon steel; stainless steel; and a unique, plastic over-molded design for specialized applications.

Our components are lighter, stronger, more cost effective, and more durable than either powdered metal or fine-blanked components. In addition, PaceMaker’s patented design allows for increased air gap while our exclusive precision stamping process enables SPC-capable run-outs superior to most current designs.
