5V,12V,24V power supply single ended output optical model. 

SE22 is an high performance, low cost, hollow shaft encoder, very easy to assembly on shaft with diameter ranging from 1.5 mm to 8.0 mm.
According to the model, the device provides one or two (or two plus index) incremental encoding square wave signals outputs. The device is very suitable for speed and incremental position detection on the applications requiring high reliability, very good performances, easy and fast assembly and a good performance/price ratio. The encoder is available with several resolutions, shaft diameters and output circuits. In the current data sheet the 5V power supply, single ended output, optical model is described.
The encoder is also available with 12÷24V power supply and differential output (line-driver); for aggressive environments a magnetic model is going to be developed.
