Incremental Rotary Optical Kit Encoders KX21 - Duncan Electronics Division - #1

Incremental Rotary Optical Kit Encoder

KX21

Series

The KX21 Series kit encoders provide a static mounting, setscrew secured disc/hub option to comple­ment the patented press on hub available in other BEI modular encoder designs.

An installation tool is provided for concurrent air gap and electron­ics alignment. Monolithic Opto IC electronics provide jitter-free outputs, without tight controls on shaft endplay or runout.

Options for the KX Series include index and complementary outputs from a 26LS31 line driver. The physical location of the index pulse has been optimally located for mechanical alignment during instal­lation. Strain reliefs are provided for flat ribbon cable, round cable or discrete wires.

Mounting on a 1.812 inch diam­eter bolt circle, the KX Series is per­fect for 2 inch diameter servo and stepper motors, as well as the other high volume OEM applications.
