Product Description:
The HS20036070221 is a rotary incremental encoder built by Danaher within the Dynapar Encoders series. By converting mechanical rotation into synchronized electrical pulses, the unit supplies real-time shaft position and speed data to drives, PLCs, or motion controllers, allowing closed-loop regulation of conveyors, presses, and automated tooling. Its through-bore design slips over a host shaft and secures with a flexible tether, allowing the encoder to provide feedback without additional couplings or brackets.
The encoder delivers an output of 360 PPR, meaning one full revolution produces 360 evenly spaced pulse cycles that a control system can count for 1° angular resolution. Signals are buffered by a 7272 push-pull driver that can both source and sink current, and each channel supports a continuous sink/source current of 40 mA for connection to high-speed digital inputs. The housing is sealed to NEMA 4/IP65, protecting it against dust ingress and low-pressure water jets encountered on factory floors. A minimum bandwidth of 100 kHz allows the electronics to reproduce pulse trains accurately at higher rotational speeds. The 7-pin connector mates with standard cordsets for power and dual-channel ABZ signal transmission, while the ABZ format provides quadrature A and B channels plus an index Z pulse for homing. The moment of inertia is 5.1 × 10−4 oz-in-s², minimizing dynamic loading on small servo motors.
The mechanical interface accepts a 1/2 in bore and requires only 0.80 in of shaft engagement, making it compatible with compact motor flanges. The codewheel and bearings tolerate a maximum speed of 6000 rpm without loss of accuracy. A maximum starting torque of 12.0 oz-in limits friction so low-power axes are not overloaded during startup. The maximum overall mass of 10 oz reduces the mounting load on lightweight frames. Additional mechanical limits include ±0.050 in of shaft end play and ±0.005 in of runout, ensuring repeatable gap spacing between the sensor and codewheel.
