Product Description:
The AI2500122B10K is an absolute rotary encoder built by Danaher and supplied within the Dynapar Encoders series. It converts mechanical shaft angles into digital words that motion controllers use for closed-loop positioning in machinery and material-handling systems. The encoder uses a single-turn design that provides a distinct position code across one complete 360-degree rotation. This design is suitable for axes that operate within one revolution or return to a reference position at the end of each cycle.
Its absolute measurement system reports the shaft position immediately after power is restored without requiring an external homing sequence. The optical glass disc provides a resolution of 12-bit, yielding 4,096 discrete position codes per revolution. An absolute mechanical accuracy of ±0.01° mechanical and repeatability of ±0.002° mechanical support precise positioning in servo applications. A 3/8-inch shaft diameter accommodates commonly used couplings, and the rotor can operate at speeds up to 10,000 rpm without signal degradation. The square flange mounting arrangement helps align the encoder body accurately with the machine frame. The enclosure carries an IP67 rating, providing protection against dust and temporary immersion in water. Position values wrap from the highest code to the lowest code after each complete shaft revolution, consistent with single-turn absolute operation.
The case has a 2.5-inch square mounting face, providing a compact footprint for servo feedback installations. Its aluminum body keeps the encoder lightweight while conducting heat away from the internal electronics. Front and rear O-ring interfaces help preserve the enclosure seal around the housing joints. Precision bearings support the rotating assembly during continuous cyclic operation and help maintain stable shaft alignment at elevated speeds. Torque is transferred through a stainless steel shaft that resists corrosion in humid operating environments. The optical sensing system reads the patterned glass disc without mechanical contact, reducing wear within the measurement assembly. Digital absolute output allows the connected controller to identify the angular position directly rather than calculate it from incremental pulse counts. This operating method also preserves the reported position after a power interruption, provided the shaft remains within the encoder’s single-revolution measurement range.
