Internal encoder
The internal encoder option is a differential magnetic encoder. The internal magnetic encoder offers several advantages:
- Smaller footprint to the MDrive than an externally mounted encoder.
- Available line counts: 100, 200, 250, 256, 400, 500, 512, 800, 1000.
- Encoder in a closed environment, limited susceptibilty to dust contamination.
- Robust output sink current of 20 mA.
- May be connected as single-end or differential.
Internal Encoder Cable (6.0'/1.8m) … p/n: ED-CABLE-JST10
A mating connector kit with shells and pins is available to build your own encoder cable:
10-pin Wire Crimp … p/n: CK-13
External encoder
Gives the user the option of using an optical encoder. Available in single-end and differential configurations with the following line counts: 100, 200, 250, 256, 400, 500, 512, 1000, 1024.
| Single-end Cable (12.0"/30.5cm) | p/n: ES-CABLE-2 |
| Differential Locking Cable (6.0'/1.8m) | p/n: ED-CABLE-6 |
Combining leading all-in-one integrated step motor+driver technology with linear motion to deliver long life, high accuracy and unsurpassed repeatability, all in a package that is extremely compact and affordable.
Planetary gearbox
Efficient, low maintenance Planetary Gearbox come fully assembled with the MDrive23Plus, and are offered in a large number of reduction ratios in 1-, 2- and 3-stage configurations.

Communications Converters
Electrically Isolated, in-line converters pre-wired with mating connectors to conveniently set parameters and program a single MDrivePlus via a PC USB port.
| Converter Part Number | Mating Connector Type |
| MD-CC300-001 (USB to SPI) | 10-Pin IDC |
| MD-CC303-001 (USB to SPI) | 12-Pin Tyco |
| MD-CC301-001 (USB to SPI) | 19-Pin M23 Circular |
If building your own cabling, you will need:
- SPI inline converter or PC parallel port
- Cabling with appropriate mating connectors for the MDrive model selected
Prototype Development Cables
Prototype development cables are designed to speed test/development with pre-wired mating connectors that have flying leads other end. No prototype development cables are available for the MDrivePlus using the 12' Flying Leads or Pluggable Clamp Terminal Strip.
| Prototype Development Cable P/N | Mating Connector Type | Signal Type |
| PD12-1434-FL3 | 12-Pin Locking Wire Crimp | I/O, Power & Communications |
| MD-CS100-000 | 19-Pin M23 Circular (Straight) | I/O, Power & Communications |
| MD-CS101-000 | 19-Pin M23 Circular (Right Angle) | I/O, Power and Communications |
These Prototype Development Cables will ONLY be used if you are using your own SPI communications converter.
If building your own cabling, you will need:
- Appropriate mating connector and crimp pins if required (Mating connector kits are available for Locking Wire Crimp style connectors)
- Crimp tooling (Locking Wire Crimp) or solder station (19-Pin M23)
- Shielded twisted pair cabling
Mating Connector Kits
Mating Connector Kits are used to build your own cables. Kits contain 5 mating connector shells with pins. Cable not supplied. Manufacturer crimp tooling recommended.
| Mating Connector Kit P/N | Mating Connector Type | Shell Mfg. P/N | Crimp Pins Mfg. P/N |
| CK-01 | 10-Pin IDC | Samtec: TCSD-0501-N | -- |
| CK-03 | 12-Pin Locking Wire Crimp | Tyco: 1-794617-2 | Tyco: 794610-1 |
| CK-13 | 10-Pin JST Locking Wire Crimp for Internal Encoder | JST: PADP-10V-1S | JST: SPH-001T-P0.5L |
