Product Description:

The AI2500102B62E belongs to the Dynapar Encoders series produced by Danaher. It is an absolute optical encoder used in industrial automation systems to provide unambiguous shaft position feedback to motion controllers and PLCs. The device combines an optical code disk with onboard electronics to deliver a single-turn digital position value, simplifying homing routines and improving machine startup times.

The encoder attains an absolute accuracy of ±0.01° mechanical, so the electrical reading never deviates from the actual shaft angle by more than this margin under rated conditions. Its housing carries an IP67 rating, which protects the optics and electronics against dust ingress and temporary immersion during washdown or outdoor service. For data exchange, the unit uses the Profibus-DP interface; this fieldbus transmits the 10-bit position word and status diagnostics over a single shielded pair to distributed controllers. A native resolution of 10 bits divides each revolution into 1,024 discrete counts, enabling fine speed regulation on servo axes. The encoder supports a maximum shaft speed of 10,000 rpm, permitting direct coupling to fast spindle or conveyor shafts without gearing.

The cylindrical body has a length of 64.8 mm, allowing installation inside compact motor frames while still accommodating the internal code wheel and integrated T-coupler. A stainless-steel shaft with a 3/8-inch diameter mates with standard flexible couplings and minimizes runout. The electronics draw only 220 mA from the 5 V supply, which eases loading on encoder power rails inside multi-axis cabinets. Repeatability is specified at ±0.002° mechanical, so the reported position returns to the same numerical value after a full-cycle movement. This consistency supports closed-loop control that relies on stable backlash compensation.
