This graph illustrates a comparison of Bourns® model AMM20B to contacting technologies. The model AMM20B position sensor with sintered bronze bushing provides an extremely long-life over traditional contacting multiturn potentiometers. This is very important in applications where the cost of replacing the sensor is high, as well as applications where the sensor is in a remote location with limited access for repair or replacement. This non-contacting device provides a long-life and reliable solution, reducing the cost of repair and maintenance.
