Product Description:

The AI2500132B02K is an absolute optical rotary encoder produced by Danaher for the Dynapar Encoders series. It translates mechanical rotation into digital angular values used by PLC and motion-controller loops in automated machines. By delivering immediate position data, the encoder supports coordinated moves on indexing tables, pick-and-place axes, and packaging equipment where repeatable alignment is necessary.

Its aluminum housing measures 64.8 mm in length and has an IP67 sealing rating, allowing the unit to operate in washdown areas and dusty conveyor lines. A hardened stainless steel shaft runs through precision bearings and permits continuous operation at speeds up to 10,000 rpm without disrupting the optical system. Positional repeatability of ±0.002° allows controllers to return to the same angle during successive cycles, while an internal photodiode array divides each turn into 13-bit increments. A shaft diameter of 3/8 in. accommodates standard collets, and the square flange mount secures the body rigidly to motor end bells. A glass code disc maintains scale integrity during thermal changes and vibration. These features support accurate position measurement under demanding industrial operating conditions.

During short acceleration events, the assembly withstands momentary speeds of 12,000 rpm, providing headroom for rapid indexing motions that exceed its continuous speed rating. System accuracy is maintained within an absolute error band of ±0.01°, reducing the need for in-process recalibration on equipment that must cut, form, or apply labels at tight angular tolerances. The installation footprint has a 63.5 mm flange register, which matches many legacy resolver mounts without requiring adapter plates. Because the sensing element tracks only one revolution, the encoder uses a single-turn design suited to shafts that return home during every cycle and do not accumulate multiple turns.
