Ordering Information
	
Encoder Type
| Option | Description | 
|---|---|
| -CT | Continuous Travel Internal Encoder | 
Encoder Output Options
| Option | Description | 
|---|---|
| -AS | Standard feedback device; 1 Vpp sine wave output; multiply the selected stage resolution by the encoder multiplier to get final resolution of counts per rev | 
| -X5 | Square-wave digital output which includes a 5-times multiplier; multiply the selected stage encoder lines by 20 to get the final resolution of counts per rev* | 
| -X10 | Square-wave digital output which includes a 10-times multiplier; multiply the selected stage encoder lines by 40 to get the final resolution of counts per rev* | 
| -X25 | Square-wave digital output which includes a 25-times multiplier; multiply the selected stage encoder lines by 100 to get the final resolution of counts per rev* | 
| -X50 | Square-wave digital output which includes a 50-times multiplier; multiply the selected stage encoder lines by 200 to get the final resolution of counts per rev* | 
| RE-ABS | Rotary encoder, absolute - contact factory (compatible with HPe, HLe, CP, and CL drives only) | 
Note: * indicates this includes controller quadrature; X5, X10, X25, X50 square-wave encoder options have limited bandwidth and may not reach stage max speed. Please contact factory to confirm speed per stage.
Limit Options
| Option | Description | 
|---|---|
| -UNLIMITED | No travel limits or hardstops; valid only with -CT encoder type | 
| -LIx | Normally-closed limits at x degrees total travel, where x = 10/20/30/60/90/120/180/240/300/340; integrated hardstops 5 degrees past LI limit switch angles; other travel angles available by special order; increases stage height by 10 mm; can be used with -CT or -LT encoder types; ALAR-250 and ALAR-325 hardstops are special order only; contact the factory for pricing |
