The Dynapar G0548021 (S21-2048.020) is an incremental optical rotary encoder from the Series E14 miniature line, delivering 2048 pulses per revolution (PPR) in a two-channel quadrature (A/B) format with optional index (Z) output. It features 5-15 VDC input power at 80 mA max, 7272 line driver outputs capable of 40 mA sink/source, and a frequency response of 100 kHz min, with squarewave signals exhibiting <1 µs rise/fall times into 1000 pF loads. Mechanical specs include a rugged metal housing (NEMA 12/IP54), shielded or sealed bearing options with low starting torque (0.1-0.43 oz-in max at 25°C), 5,000 RPM max shaft speed, 5 lb radial/3 lb axial shaft loading, and operation from 0 to +70°C in humid environments up to 98% non-condensing. Suitable for precision motion feedback in compact servo motors, robotics, and high-speed automation where space constraints and reliability under shock/vibration are critical.
