Product Description:
The 22M03605343 incremental encoder is produced by Danaher as part of the Dynapar Encoders series. It mounts on a drive shaft and emits quadrature signals with an index pulse, allowing motion controllers to track position and speed in automated assembly lines and conveyor systems. By converting mechanical rotation into electrical pulses, the device supplies real-time feedback for closed-loop servo control and repeatable motion. Its compact housing simplifies installation alongside small servo motors or gearheads where mounting space is limited.
The stainless steel shaft has a diameter of 6 mm and can operate at speeds up to 6000 rpm without exceeding the bearing limit. The shaft supports a maximum axial load of 30 lb and a maximum radial load of 40 lb, protecting the internal optical components from misalignment when pulleys or couplings impose thrust. Its resolution is 360 PPR, meaning each revolution produces 360 equally spaced quadrature cycles that the connected controller can use to calculate angular movement. An inertia of 1.3 × 10⁻⁴ oz-in-s² reduces the rotational load reflected to a connected motor. Starting torque is 2.5 oz-in, which supports use with smaller motors that have limited torque available during initial movement. Installation uses an M3 × 0.5 mounting thread on a 50.8 mm bolt circle, allowing the housing to be secured without an additional mounting adapter.
Differential line drivers transmit position data at a frequency of at least 120 kHz, supporting high-speed counting over extended cable runs. The separate index channel operates at a frequency of at least 50 kHz, allowing a PLC or motion controller to capture a single-turn reference at high shaft speeds. Each output can sink or source up to 40 mA, while the encoder electronics draw no more than 110 mA from the 5 V supply commonly available through encoder interfaces. The differential output includes an index signal and provides strong noise immunity in industrial installations. A preattached 6 ft molded cable helps limit signal reflections and preserves data integrity during high-frequency operation.
