Alps Alpine EC21A Ring-Type Encoders

Alps Alpine EC21A Ring-Type Encoders feature a 10mA, 5VDC electrical rating and a two-phase A and B output signal. These encoders offer 100MΩ 250VDC insulation resistance with an available 9/18 or 15/30 pulse/detent count. Alps Alpine EC21A Encoders measure 21.6mm x 21.6mm x 4mm while the actuators measure 15mm in length. Alps Alpine EC21A Ring-Type Encoders withstand 50,000 life cycles and can operate in temperatures ranging from -40°C to +85°C.
