Dynapar G0539408 AX71/1214EK.42DPA-F0 Incremental Optical Rotary Encoder

The Dynapar G0539408 (model AX71/1214EK.42DPA-F0) is an incremental optical rotary encoder providing two-channel quadrature (A/B) output with optional index (Z) channel, supporting resolutions from 100 to 2540 pulses per revolution (PPR). It operates on 5 VDC ±5% at 80 mA max or 12/15 VDC ±10% at 80 mA max (excluding loads), with 7272 line driver outputs rated for 40 mA sink/source and a frequency response of 100 kHz minimum. Mechanical specifications include a maximum shaft speed of 5000 RPM, bearing life of (16 × 10^6 ÷ RPM) hours at max load, 5 lb radial and 3 lb axial shaft loading, moment of inertia of 3.8 × 10^{-5} oz-in-sec², and weight of 3.0 oz max; environmental ratings cover 0 to +70°C operating temperature, up to 98% humidity (non-condensing), and NEMA 12/IP54 enclosure (dirt-tight, splashproof) in a rugged metal housing. Suitable for servo, flange, face, or foot mounting with compatible flexible shaft couplings (CPL series), it suits applications requiring precise position/speed feedback in industrial machinery, motors, and gear reducers.
