SAS and SBS Series
COMPACT DIRECT DRIVE OR GEARED, PERMANENT MAGNET STEPPING MOTORS

These stepping motors, both direct drive and geared, are designed for applications where space is limited and precise performance is required. Direct drive motors are available for 6, 12, or 24 VDC operation and provide a choice of 7.5 or 15 step angle. Geared motors have a range of step angles from 0.0125 to 7.5, and output speeds @ 200 p/s from 0.42 to 250.0 rpm.

NOTES
1. Hurst Stepping Motor Controllers may be used to drive SAS and SBS stepping motors.
2. Standard lead wire configuration is 6 leads. Click here for standard lead wire color code and switching sequence.
