Improving the Quality of Life through the Power in Light
QPhase
Design Features:
500 kHz Fundamental Frequency Response Low profile, 0.87 assembled height
Bearing design simplifies encoder attachment Resolutions 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 EncodersDescription:
Quantum Devices, Inc. Model QD145 provides an improved feedback solution in applications typically using modular
encoders. With an over all height of just only 0.87 and the stability of a bearing encoder design, the model QD145 can
provide significant performance upgrades in applications limited by traditional modular encoder solutions. Outputs
consist of a quadrature with reference pulse and three-phase commutation, which can be configured with either the
industrial standard 5 volt RS422A Line Driver or the 5 to 26 volt OL7272 line driver. A flexible member allows for much
greater tail shaft run out than can be tolerated by modular encoder designs, plus it provides 30 degrees of rotation for
commutation timing. A housing constructed of conductive carbon fiber composite provides the EMI shielding of an allmetal housing and the performance of a lightweight robust assembly.

ENCODER INSTALLTION INSTRUCTIONS
1. Using two fingers slide the encoder onto shaft.2. For additional security, Loctite can be applied to the encoder hub set screws. Remove the encoders set
screws and using tip of toothpick apply appropriate amount of Loctite thread locking adhesive. A non-permanent adhesive is recommended.
3. Insert and tighten encoder set screws using a .050 hex wrench. Typical torque range of 50 to 80 oz-in.
4. Fixture the stainless steel flex mount to the mounting surface with #6-32 button head screws.
For brushless motors requiring commutation timing: Encoder drawings indicate position of encoder hub to encoder body at Z (index). Rotating the hub to this
position allows for known U channel transition state (prior to step one above).
Powering appropriate motor windings allow for locking motor shaft location to match the appropriate U
transition (prior to step one above).
While mechanically back driving the motor, monitor motor winding EMF position to the powered encoderposition. Rotate the encoder stainless steel flex mount to achieve accurate timing of encoder commutationfeedback channels to the appropriate motor winding EMF. Tighten the screws retaining the encoder
stainless steel flex mounts.

Design Features:
Miniature Size, 20mm (0.787") Diameter Resolutions up to 2048 lines per revolution direct read Single ended and differential outputs Patent pending unique sensing system Long service life Conductive carbon fiber housing IP 50 sealing High noise immunity Low supply current requirements
Description:
Quantum Devices, Inc. Model QD787 is intended for applications requiring high performance, high-resolution
digital feedback in a very small package. The model QD787 provides the resolution of larger encoder packagesbut in a package only 20mm (0.787") in diameter. Outputs can be configured in either single ended, open
collector or internal pull up resistor, or with an industrial standard RS 422A differential line driver. QDI's patent
pending sensing scheme embodies a much simplified encoder design, which ultimately results in longer servicelife, and less down time due to feedback device failure. The encoder housing is constructed of a conductive
carbon fiber composite that provides the EMI shielding of an all metal housing and performance of a
lightweight robust assembly.

DESCRIPTION
Quantum Devices, Inc. Model QDH20
provides an improved feedback solution
in applications typically using a standardsize 20 package. The QDH20 provides
encoder feedback in standard industrial
mounting configurations with superb
mechanical and environmental protection.
Outputs consist of a quadrature A & B with reference pulse Z as a standard feature. The output
can be configured with either the 5 to 26 volt OL7272 line driver or open collector outputs. TheQDH20 features two heavy-duty bearings holding the output shaft, and two more bearings along
with an integral flexible spring mount to isolate the working pieces of the encoder from
mechanical stresses.
DESIGN FEATURES 500 kHz Fundamental Frequency Response
High Operating Temperature (100C)
Resolutions up to 5000 lines per revolution direct read
Flange and Servo Mount Options
Solid shaft sizes up to 10mm Hollow shaft sizes up to 0.625 Diameter
High Noise Immunity
TYPICAL APPLICATIONS
