Alps Alpine EC28A/EC28C Ring Type Encoders

Alps Alpine EC28A/EC28C Series Ring Type Encoders are low-profile 28mm encoders. EC28A/EC28C is available with 18 or 30 detents and 15 or 18 pulses. The encoders have a current rating of 10mA, 5VDC, an operating life of 50,000 cycles, and an operating temperature range of -40°C to +85°C (EC28A) or -40 to +90°C (EC28C). A smooth click sensation during rotation gives an excellent feel to the encoders. Alps Alpine EC28A/EC28C Series Ring Type Encoders applications include automotive HVAC and audio systems and major home appliances.
