SM17205M-LTR Class 5 M-Style SmartMotor™

The SM17205M-LTR (LTR-17) SmartMotor™ is engineered for robust and reliable operation in extremely frigid environments and at high altitudes.An onboard internal heater ensures start up in temperatures below -40°C and IP62 sealing is standard.

Key Features

  • Integrated drive and controller, which reduces wiring, increases reliability, simplifies installation and reduces setup time
  • Cold start-up from -40°C
  • Storage to -65°C
  • Onboard heater to bring internal circuit up to startup temperature
  • Shock and vibration resistant to 6G 10-2000Hz
  • Four 5V TTL sourcing inputs
  • IP62 sealed
  • Magnetic, single turn absolute encoder
  • RS-422 differential communication
  • FAA approved, click-fit connector
  • For RoHS exempt applications only
    (the LTR motors contain lead-based solder on some internal components to achieve increased reliability over greater thermal ranges)
       Plus, the LTR models include Class 5 SmartMotor features, such as:
  • Position, velocity or contouring mode
  • Encoder commutation with trapezoidal, advanced trapezoidal and sine commutation modes
  • Powerful Basic-like command language with over 200 operators: motion, IO, program flow, data handling, math, communications
  • Nonvolatile program and data storage
  • And more
