.

The QD-H20 is an idea replacement encoder for size 20 and size 25 industrial applications.  It is an IP-66 sealed rotary incremental encoder.  This high IP rating provides outstanding environmental protection with all of the line count and output options of the QD-145 incremental encoder.

The QDH20 style Industrial Rotary Encoder is typically used in applications such as Machine Control, Process Control, Elevator Controls, Agricultural Machinery, Textile Equipment, Robotics, Food processing, Conveyors, Material Handling, as well as, any application where water/contaminant ingress or durability is a concern.

The QD-H20 Incremental Encoder has three styles of MS connectors, 6,7, and 10 pin, along with a flying lead option, and the ability to come with custom cable lengths.  Each connector option is possible in radial and axial configurations.

The QD-H20 Rotary Encoder boasts a wide –20 to 100 Deg. C temperature range and a 500kHz frequency response.  Multiple shaft sizes ranging from .250” to .650” in both hollow and solid shaft are available.

The rugged dual bearing set allows the QD-H20 industrial rotary encoder to handle overhung loads, such as direct mount pulleys, with side load forces as high as 40 pounds nominally and 80 pounds maximum.

About Quantum Devices Inc.
Quantum Devices, Inc. (QDI) Barneveld, WI, was established as a Wisconsin corporation in October 1989, as an outgrowth of activities in the general area of optoelectronics. The main goal of QDI is to provide customers with a complete source for all stages of product design and development, starting from concept to a marketable commodity. These products include application specific Silicon Photodiodes, Optical Encoders and Light Emitting Diodes (LED) for commercial, industrial and medical applications. QDI's photodiodes and LED's are used in instrumentation for photosynthesis and photobiological research, biomedical and medical instrumentation for measuring blood sugar levels (glucometer), oxyhemoglobin and pulse rate (pulse oxymeter). One of the most dramatic products developed at QDI was the application of LED lighting systems for use as the light source for Photodynamic Therapy (PDT). Sales of QDI products include both domestic and international markets. Quality and reliability are very important concepts in maintaining our company wide commitment to overall product performance. Quality simply means continuous process improvement. We are committed to continually increasing our product excellence through increased quality and reliability. Quantum Devices, Inc. is ISO 9001 certified and the ISO Standard will provide the guidance for the vital function of maintaining our commitment to constantly improve our product quality. Quantum Devices is now proud to introduce it's new line of rotary encoders. Incorporating QDI's patented sensor technology, our QPhase™ Family of Encoders feature high resolution, increased frequency response and superior reliability over temperature (0 to 120 degrees C). QDI incremental and absolute encoders set a new standard and are backed by a 2 year factory warranty. We invite you to request an evaluation unit, additional information or price quotations. Mission Statement Quantum Devices is dedicated to the principle that light provides the power for all life on earth. We believe the quality, delivery and control of light is essential to the wellness of man and his advancement into the future.
