Product Description:

The 2201503343 is an incremental rotary encoder manufactured by Danaher as part of the Dynapar Encoders series. It mounts on a motion axis and converts shaft rotation into discrete electrical pulses that a PLC or drive uses for position or velocity feedback. By supplying two quadrature channels and an index channel, the device supports directional sensing and zero-reference detection in automated conveyors, packaging equipment, and general machinery.

This model delivers a resolution of 150 PPR, so each mechanical revolution produces 150 evenly spaced pulses per channel for precise position measurement. The encoder supports a signal frequency of at least 120 kHz, allowing reliable pulse counting when the shaft operates at high speed. The outputs use a CMOS line driver architecture, providing differential signals that resist electrical noise over long cable runs. Each output can sink or source up to 40 mA, while the electronics draw no more than 110 mA from the power supply. These current levels enable direct connection to standard 5 V or 12 V encoder inputs. The index channel is aligned at 225° ± 90° electrical, quadrature phasing is 90° ± 18°, and channel symmetry remains within 180° ± 18°, supporting consistent timing for closed-loop control.

The encoder tolerates continuous operation at speeds up to 6000 rpm, matching typical servo and stepper motor speeds. It couples to a shaft with a diameter of 1/4 inch and uses a single-ended configuration for straightforward installation. The unit has a maximum mass of 14 ounces, which helps keep the overhung load on the motor bearing low. Its bidirectional rotation sensing allows the control system to track forward and reverse motion without additional sensing hardware. Quadrature output signals indicate the direction of travel by changing which channel leads the other, while the index pulse provides a consistent reference point once per revolution.
