ALLNET 4duino Rotary Encoder (4duino_B16) - Incremental Rotary Encoder with Push Button, 20 PPR, 3.3-5V DC, for Arduino and Raspberry Pi

The ALLNET 4duino Rotary Encoder (4duino_B16) is a high-quality incremental rotary encoder designed for use with Arduino, Raspberry Pi, and other microcontroller platforms. Featuring 20 pulses per revolution (PPR) with 20 detents and an integrated push button switch, this encoder provides precise rotational feedback and a tactile click for menu navigation or parameter adjustment. The quadrature output (A/B phase) ensures reliable direction and position sensing. With a knurled 6 mm shaft and PCB mount with screw holes, it is easy to integrate into your projects. Operating voltage ranges from 3.3V to 5V DC, making it compatible with both 3.3V and 5V logic systems. The encoder offers a rotational life of 30,000 cycles and a switch life of 20,000 cycles, ensuring long-term durability. Operating temperature range is -25°C to +70°C.
