.

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.
