EC11 11mm Metal-Shaft Encoders

Alps Alpine EC11 11mm Metal-Shaft Encoders are compact, high-reliability encoders with a variety of length, pulse, and detent options. The Alps Alpine EC11 Encoders offer 9PPR to 18PPR resolution, 5V_DC operating supply voltage, and 10mA at 5V_DC current rating. The series offers a standard operating life of 15,000 cycles and versions with 100,000 cycles. The encoders operate over a -40°C to +85°C temperature range.
