Product Description:

The HA62510000340 is an incremental optical encoder produced by Danaher within the Dynapar Encoders series. It mounts on a rotating shaft and converts mechanical motion into digital square-wave channels, allowing motion controllers to track speed, direction, and position in industrial machinery. The glass code disc, stainless steel shaft, and aluminum housing form a sealed feedback assembly that withstands washdown environments while maintaining precise pulse generation for drives, PLCs, and servo systems.

The housing has a rating of NEMA 4 / IP66, which protects the internal electronics against dust and directed water jets. The signal electronics accept up to 26 VDC and draw no more than 80 mA, enabling direct connection to most differential line-driver interfaces. Channel switching supports frequencies of at least 100 kHz, while quadrature phasing remains at 90° ± 22.5° electrical and signal symmetry remains within 180° ± 18° electrical. These timing characteristics support high-speed counting and accurate interpretation of shaft direction by the connected control system. Internal geometry limits the effects of thermal growth, and a positive shaft seal prevents contaminants from entering around the bearing journal.

The shaft can rotate at a maximum speed of 5000 rpm without placing excessive load on the prime mover. It accepts combined loads of 35 lb radial and 40 lb axial before bearing life is affected. The rotor inertia is 3.0 × 10⁻⁴ oz-in-s², so accelerating the measuring assembly adds minimal dynamic error during rapid speed changes. Initial drag is limited to 2.5 oz-in of starting torque, reducing resistance when the connected shaft begins to turn. With a total mass of 1.5 lb, the encoder can be coupled directly to servomotors or jack screws in compact packaging and material-handling equipment. Its sealed housing is suitable for machinery that requires accurate feedback near dust, moisture, or routine equipment cleaning.
