The Grayhill 62AG series offers a cost-effective solution for rotary position sensing. This encoder utilizes patented light pipe technology for reliable performance and boasts a mechanical life of 1 million cycles. It finds application in automotive systems (audio, navigation), medical patient monitoring, test and measurement equipment, and consumer electronics. The encoder provides 2-bit gray code output with quadrature coding and is available with options like integrated pushbuttons and various cable lengths and terminations. Its robust construction and environmental specifications (-40°C to 85°C) ensure reliable operation in demanding environments.
