Multiplexed absolute encoders at low cost
East Northport, N.Y .-As many as 16 shaft inputs can be handled by a recently introduced multiplexed absolute encoder system from Computer Conversions Corp. The new encoders convert shaft inputs to binary coded decimal (BCD) or binary information corresponding directly to shaft angle with accuracy of
For reliability, the shaft transducer is a resolver-based encoder. It eliminates brushes (for longer life), brush noise, light sources, and limited resolution compared with standard encoders. These units are said to work in harsh environments such as electromagnetic interference, high temperature, moisture, and vibration.
The encoders are available with Size 11 (1.1 in. OD) transducers. Adding transducers accommodates multiple shafts. The electronics package (4.5 x 7.25 x 1.5 in.) and transducers connect with simple cabling. Interfacing to PLCs and microprocessors is also provided, with basic data update rate of 2.5 msec.
The company claims 'lowest cost per axis available today' with this product. Pricing (for Part No. MXDS90-DB-10-8) is under $250 per axis 'in reasonable quantities.' Delivery is 4 weeks.
