Product Description:
The 2201001003 is an incremental rotary encoder manufactured by Danaher within the Dynapar Encoders series. Mounted on a motor or line shaft, it converts angular displacement into digital pulse streams that controllers use for speed regulation, position verification, and bidirectional counting in automated equipment such as conveyors, winders, and small pick-and-place stations. Its open-collector interface and modest current draw allow integration with legacy counting cards as well as modern microcontroller inputs without additional line drivers.
The electronic section draws up to 110 mA from the supply, and its open-collector output can sink a maximum of 40 mA to ground when driving opto-isolators or counter cards. A frequency response of at least 120 kHz keeps pulse edges clean when the shaft reaches its rated speed of 6000 rpm. Each revolution generates 100 PPR, providing 3.6° resolution per pulse for velocity or incremental position calculations. The bidirectional rotation mode provides phased channels that allow the controller to distinguish forward motion from reverse motion. The interface is single-ended, and the built-in 2.2 kΩ pull-up is compatible with 5 to 24 V logic rails, so no external bias resistor is required.
The stainless steel shaft has a diameter of 3/8 in and withstands radial loads of 40 lb and axial loads of 30 lb without compromising bearing life. Initial drag is limited to 2.5 oz-in, allowing small fractional-horsepower motors to accelerate freely. A molded housing with a preinstalled 6 ft cable simplifies wiring and provides strain relief. Overall mass is limited to 14 oz, reducing the load on lightweight mounting brackets while providing a stable platform for bidirectional feedback. The encoder can be mounted horizontally or vertically because its shaft and bearings accommodate the stated radial and axial loads. This mounting flexibility allows the encoder to fit into compact enclosures where shaft orientation and available clearance may vary.
