Quantum Devices QD145 Encoder

Quantum Devices QD145 Encoder

The QPhase™ QD145 has been designed to eliminate the assembly hassle and hidden cost of installing modular or kit encoders onto OEM products.  The QD145 is a complete operational unit with an integral dual ABEC 5, ball bearing, insert molded hollow shaft support that provides the mechanical stability for this low profile (0.87” high by 1.45” diameter) high resolution encoder package.  Using our proprietary sensing technology we are able to obtain an incremental, 4096 PPR, plus Index pulse, without the use of interpolation schemes.  The stainless steel flexible spring mount provides for 30° rotational adjustment to permit precise commutation alignment and has been designed to allow for more motor tail shaft run out than typical modular or kit type units can tolerate.

Product options include: 120° C continuous ambient operating temperature, 4 to 12 pole three phase commutation signals for brushless motors, 5–26 VDC operating input voltages, high voltage line driver outputs on both incremental and commutation lines and standard resolutions from 200 PPR to 4096 PPR derived directly from the encoder disc.  Features include:

  • 500 kHz Fundamental Frequency Response
  • Low Profile, 0.87″ assembled Height
  • Bearing Design Simplifies Encoder Attachment
  • Resolution up to 5000 Lines Per Revolution Direct Read
  • 4, 6 or 8 Pole Commutation
  • Conductive Carbon Fiber Housing
  • Standard 1.812″ Bolt Circle Mounting
  • Through Shaft Sizes up to 0.375″ Diameter
  • High Noise Immunity
  • Cost Competitive with Modular Encoders
