UNDERSTANDING HYBRID PART NUMBERS

A standard Haydon motor part number consists of 7 digits to 10 digits – XXXXX-VV-XXX.

·	The first two digits indicate the motor’s series or size (in mm). Example: 35000 Series = 35 mm sq.
·	The third digit or letter indicates the motor’s step angle Example: F = 1.8° non-captive; H = 1.8° captive or external linear; J = .9° non-captive; K = .9° captive or external linear (NOTE: External linear actuators have the prefix “E” to distinguish them from the captive actuators; High Temperature actuators require the prefix “T”)
·	The fourth digit indicates the number of leads. (4 leads for bipolar; 6 leads for unipolar).
·	The fifth digit indicates the travel per step (see chart) Example: N = .00012” (.003048 mm)
·	The sixth and seventh digits indicate the motor’s voltage. Standard voltages are 5 (05) and 12 (12) V. We also have low inductance coils available for chopper drives. Custom voltages are also available.
·	Digits eight, nine, ten indicate captive motor travel
–904 = .354" (9.0) travel...(ONLY SIZE 8) –905 = .500" (12.7) travel –907 = .750" (19.1) travel		–910 = 1.00" (25.4) travel –912 = 1.25" (31.8) travel –915 = 1.50" (38.1) travel	–920 = 2.00" (50.8) travel –925 = 2.50" (63.5) travel –900 = Standard External Linear Motor with grease and flanged nut

SCREW LENGTH OPTIONS: For non-captive shaft and external linear motors various screw lengths are available to accommodate any travel requirement.
