Absolute Multi Turn Inductive Encoder

SEA MOTION is a trusted China absolute multi turn inductive encoder supplier, providing high-performance multi-turn absolute inductive encoders for multi-cycle continuous rotary motion measurement. Breaking the limitation of single-turn positioning, this encoder accurately records rotation angle and total turns within multiple rotations via inductive sensing and intelligent signal processing. It stores all position and turn data permanently, with no data loss after power off and no need for repeated zero calibration.

Installation Diagram                  Tools required for installation

Phillips torque screwdriver

1.5mm hex key torque wrench (metric)

4 x M2x5.5 Phillips pan-head screws with flat washers

2 x M3x3 hex socket cup-point set screws

8 x M1.6x6 Phillips countersunk screws

Installation sequence

Rotor Installation:

① Fit the encoder rotor onto the motor shaft and position it correctly;

②Use DP460 adhesive to securely bond the encoder rotor plate to the shaft sleeve.

[Note]:

1) If the rotor height requires adjustment, perform the tightening step only after the adjustment is complete;

2)To prevent the screws from loosening, apply thread-locking adhesive to the threaded holes beforehand or use pre-coated screws.

The recommended tightening torque is 7 ± 0.2 kgf·cm.

Stator Installation:

① Place the encoder stator onto the mounting surface and align the four screw holes;

② Using a Phillips torque screwdriver, drive in the four screw assemblies one by one

(M2x5.5 Phillips pan-head screw + flat washer assembly).

[Note]: To prevent the screws from loosening, apply thread-locking adhesive to the threaded holes beforehand or use pre-coated screws. Recommended tightening torque: 2.8 ± 0.2 kgf·cm.
