The Fundamental Operation ...

 

High resolution, totally sealed
flexplate mounted
size 25 integral pinion BEI encoder


 

Encoder_Flex_Plate_Mounting.jpg (10824 bytes)

 
We can supply you with flexplate mounted encoders or resolvers with integral hobbed pinion shafts that mate with precision rack for 0.002 mm or 0.0001 inches (or higher) resolutions without speed increasers.

This gives you a viable alternative to Inductosyn scales or glass scales for feedback

blueribbon.gif (909 bytes)Integral Pinion Transducers 

Encoders with up to 10,000 pulses/rev. are compatible with the CNCs, PLCs and PCs using digital-incremental feedback like Allen-Bradley, Dynapath, Fagor, GE-Fanuc, Vickers, NUM, Siemens, Mitsubishi, and others.

The encoders and resolvers are totally sealed with MS connectors; and are available with either 1 mm or 1/10 inch circular pitch, 20 tooth integral (Quality 15) pinions for 0.002 mm or 0.0001 inch resolution as commonly required.    Ten tooth, 1/10 inch circular pitch pinion shaft encoder for interfacing with 0.100 inch pitch rack are also available.  Other resolutions are available to 0.00002 inches (or 0.0004 mm).
