Product Description:

The 3210001440 is an incremental rotary encoder built by Danaher within the Dynapar Encoders series. It converts shaft rotation into discrete electrical pulses that allow motion controllers to track position, velocity, and direction in industrial automation cells, packaging lines, and motor drives. Bidirectional quadrature signals from this encoder help systems detect forward or reverse movement and maintain closed-loop control without relying on mechanical limit switches.

The device generates 1000 PPR, so each revolution produces one thousand pulses, providing 0.36° of resolution for velocity and displacement calculations. Its sensing electronics accept signal frequencies up to 120 kHz, enabling accurate feedback even when the shaft approaches maximum speed. Control power demand stays low because the input stage draws no more than 80 mA from the 5 V supply. Differential outputs based on a 7272 line driver can sink or source 40 mA, allowing long cable runs without significant signal degradation. Edge fidelity is preserved by a maximum rise or fall time of 1 µs, which minimizes timing jitter between channels A and B. Quadrature formatting and a separate index channel support electronic homing routines.

The stainless steel shaft measures 3/8 in in diameter, has a single-ended design, and can operate continuously at speeds up to 6000 rpm without exceeding bearing or sensing limits. Startup drag remains minimal because the required torque is only 2.5 oz-in, and the combined rotor and code-disk inertia is 9.0 × 10⁻⁴ oz-in-s², so the encoder places little burden on acceleration. Total mass does not exceed 14 oz, which reduces the load when the encoder is mounted on small motors or supported in a cantilevered arrangement. The encoder uses a six-pin MS termination for its electrical connections. It also supports forward-reverse counting so the connected controller can determine the direction of shaft rotation from the output channels.
