Amphenol is a single source for high-tech sensors for both manufacturers and consumers. With more than 65 years experience, Amphenol leads the way in the design and manufacture of high quality sensors.

Our flange mount gear tooth speed sensors have  been designed to precisely calculate the speed and direction in demading enviroments such as vehicle’s transmission.

Custom product design packaging can be easily provided to 
meet any form, fit and function including the choice of
wire harness and interface connector.
