Product Description:

The AI2512142192F is an absolute rotary encoder manufactured by Danaher for the Dynapar Encoders series. Designed for position feedback in conveyors, pick-and-place axes, and other motion assemblies, it converts shaft rotation into networked digital data that drives servo loops and PLC position registers. Combining single-turn and multi-turn tracking, the device reports both the angle within one revolution and the total number of revolutions, allowing equipment to retain its position after power interruptions.

During operation, the housing carries an IP64 rating, protecting the optical stack from dust ingress and splashing water encountered in typical installations. The electronics draw only 250 mA from the control supply, a value low enough for most fieldbus power budgets, while a DeviceNet interface transmits the position word in binary format through an M12 five-pole connector. Within each revolution, the sensor delivers a 14-bit single-turn resolution, and its gear set tracks an additional 12 bits of multi-turn data, providing 16,384 counts per turn across 4,096 turns. A maximum mechanical speed of 10,000 rpm permits mounting on high-speed spindles without oversampling errors. Linearity remains within ±1/2 LSB, and starting torque is less than 1.4 in-oz. The 2.5-inch square flange and 73.8 mm mounting length follow a common industry mounting pattern.

Measurement integrity is supported by an absolute accuracy of ±0.01° mechanical and repeatability of ±0.002° mechanical, making the encoder suitable for tight indexing or registration duties. A hardened stainless steel shaft measuring 3/8 inch in diameter connects directly to standard flexible couplings, while the square flange keeps the body concentric with the drive. The encoder’s binary output code simplifies decoding in controllers with limited processing resources, while consistent linearity and low drag help maintain constant servo stiffness across the full speed range.
