In rotary encoders with integral bearing and stator coupling, the graduated disk of the encoder is connected directly to the shaft to be measured. The scanning unit is guided on the shaft via ball bearings, supported by the stator coupling. During angular acceleration of the shaft, the stator coupling must absorb only that torque resulting from friction in the bearing, thereby minimizing both static and dynamic measuring error. Moreover, the coupling mounted on the stator compensates axial motion of the measured shaft. Other benefits of the stator coupling are: Simple mounting Short overall length High natural frequency of coupling Hollow-through shaft possible

Engineered on the basis of a compact innovative technology, the incremental encoders E30, offer great accuracy and reliability in a small size, and an excellent price/performance ratio. The incremental encoders E30 are available both in the bidirectional version (E30) and in the bidirectional type with zero reference pulse (E31); the pulses per revolution no. ranges from 2 to 12500. Their body diameter measures 30 mm only, with shaft diameter 4 or 6 mm. The encoder E30 is housed in an ABS plastic case, with axial cable or connector outlet. The output signals can be provided in NPN open collector, push-pull or line-driver format.
