  • Page 2: General Description

    The encoder 35x24x14mm with a weight of 16g. The transmitter (encoder) part is simply mounted on the rotating shaft with a special fiber reinforced tape. The data transfer between transmitter and receiver is digital. The powering of the transmission part by the T1-PCM-IND is inductive!.

  • Page 5 Autozero LED: Yellow ON- successful AZ Yellow OFF- not successful AZ if flashing, call support of KMT, error in EPROM SL LED: Red ON = if error of data transmitting SL LED: Red Flashing = distance to far Power ON LED: Red ON = if power switch on Output to Powerhead: via 6-pol.
  • Page 6 Pin connection & block diagram At high RPM we recommend to solder the GAIN jumper! On the back side PCB are solder bridges what can use instead of jumper! Caution: The Powerhead must be fixed in the middle of the coil in a distance from 5 to 25 (35)mm. Don’t introduce any metal parts between or near the Powerhead and the shaft.
  • Page 7 Mounting example of power head / pickup: Ideal distance 10mm Right installation Wrong installation, head position is 90° wrong to the coil and will not work! Technical Data are subject to change without notice! Version 2018-11...

    Shaft installation Fix with 2 layers of mounting tape around the shaft 2 layers (layer by layer) of the special ferrite tape around the shaft Coil, depends of shaft diameter 5-18 parallel windings of 0.5 CUL wires, see table for help. (Enamelled copper wire) Fix with 2 layers of mounting tape around the coil Technical Data are subject to change without notice!
  • Page 12 10 layers of the special mounting tape around the shaft. We recommend soldering all pins of the T1-PCM-STG! We recommend add. use a steel hose clamps for final fixing!! Caution: Fix T1-PCM-STG module with at least 10 layers of the special mounting tape around the shaft. Depending on the shafts RPM and diameter particular attention needs to be paid to the safe mounting of the components.
  • Page 13 Find the correct amount of windings The number of windings depends on several factors. The most important influential factors are the diameter, the materiel of the shaft and the environment around the shaft. The table standing below will help you to find the right number windings for steel shafts.
