Servo-Tek has an innovative optical encoder which is the PTS Series DC Tachometer Encoder with 1-1024 cycles per revolution. The PTS series tach-encoder combination pro¬vides both velocity and position signals from one device. By having the tachometer and encoder on one common shaft, mounting and coupling requirements are reduced. The DC tachom¬eter generator can provide an analog signal from 12,000 RPM down to zero speed. Since the DC tachometer generator reverses polarity from CW to CCW rotation, direction can be sensed almost instantaneously. Different mounting arrange¬ments are available for your tach-encoder such as face mount, square end bell, round end bell and even an adaptor that will fit PY mounting kits. Servo-Tek manufactures sealed DC tachometer generators which could be incorporated into your tach-encoder as well as low ripple units.
The specifications include resolution of Up to 1024 lines/rev, channels are single or dual and voltage of 5 VDC, 12 VDC. The body diameter is 2.00 inches.
The Tachometer specifications have an output voltage of 1 to 50 VDC/1000 RPM, shaft diameters of .120 .187 .250 Others and mounting configurations that are Face, Flange or Servo. The body diameter is 1.134 inches.
