Product Description:
The 2201002245 rotary encoder is manufactured by Danaher within the Dynapar Encoders series. It mounts directly on a host shaft and converts mechanical rotation into two square-wave channels that controllers count for velocity and incremental position feedback. By supplying real-time data, the device helps industrial drives, conveyors, and tensioning systems maintain synchronization and detect directional changes without extensive signal-conditioning hardware.
A resolution of 100 PPR provides precise incremental position feedback, while a maximum mechanical speed of 6000 rpm allows the encoder to monitor mid-range spindles without exceeding its speed limit. The electronics follow signal transitions at frequencies up to 120 kHz, and the response time is less than 1 µs, supporting tight control-loop timing. A starting torque of only 2.5 oz-in limits the frictional load placed on low-power servomotors. The stainless steel hub withstands an axial force of 30 lb, providing resistance to thrust transmitted through connected couplings. A CMOS line-driver stage supplies complementary differential outputs. The two channels have 90° ±18° quadrature and 180° ±18° symmetry, which helps preserve count integrity during bidirectional motion.
The encoder supports a radial load of up to 40 lb, protecting it when belt tension or chain pull applies force perpendicular to the shaft. A molded cable with a length of 15 ft allows routing to control cabinets without intermediate junctions. Its overall mass is limited to 14 oz, so the sensor adds little weight to moving assemblies. The rotor has a moment of inertia of 1.3 × 10⁻⁴ oz-in-s², minimizing resistance during acceleration and deceleration. A 1/4-inch double-ended shaft permits coupling to tachometer wheels or secondary encoders. The differential output architecture also helps reject common-mode electrical noise as signals travel through the attached cable.
