Series 292 20mm Optical Ring Encoder Compact 20mm size package 3 million cycles rotational life (1 million cycles with detent) 24 PPR resolution Wide operating temperature range (-10C to +85C) 5.0 VDC and 3.3 VDC power options Integrated Schmitt trigger and pull-up resistor Applications Medical diagnostic equipment Industrial automation controls Automotive HVAC controls Infotainment controls Professional audio and lighting equipment Description The Series 292 optical ring encoder provides a reliable and durable solution to applications that require extended rotational life where traditional mechanical contacting designs fall short. The hollow shaft design allows the engineer to integrate an additional push switch or LED in the center of the unit. Power options allow for use in standard or energy efficient circuits. The integrated Schmitt trigger and pull up resistor reduces the number of components required when adding an encoder to a circuit. The reduced number of components translates into cost savings and reduction in required PCB space.
