Overview
The 9450F is the same 700 kg·cm drivetrain as the 9450D, built in the side-mounted configuration: the mounting flange moves to the sides of the case and the output carries a machined lever arm instead of a bare spline. Same 100 × 50 × 97 mm body, 895 g, 24–30 V.
The point of the F layout is the load path. A side-mounted flange takes the reaction torque across a longer bolted face, and the lever arm puts the push-pull rod in line with the load instead of hanging a linkage off a spline. On a 700 kg·cm actuator that difference is what keeps the bracket from flexing.
This page covers the TTL build: the same mechanics, commanded over a serial bus so several servos can share one signal line and be addressed individually. Useful when the actuator count outgrows the PWM channels available. This build is the side-mounted F configuration.

What’s in the box
- 1 × XQ-S9450FTTL servo
- 1 × 7075 aluminium horn
- 1 × mounting screw pack
The J30J-9TJL mating cable is not included; it is ordered separately to suit your harness.
How to size it
The side flange bolts to a face, not to a tray, so the bracket has to be flat and stiff over the full 122.7 mm width. Shim it rather than preloading one corner — a twisted flange shows up as current ripple at the output, not as a servo fault.
Same current budget as the D: 22.5 A stall at 30 V, 450 mA idle. The lever arm also means the load is applied off-axis from the shaft centre, so check the side load against the bearing rating before extending the arm.
FAQ
How is the 9450F different from the 9450D?
Mounting and output: the F is side-mounted with a lever arm, the D has the standard ear-mount case with a bare 25T spline. Drivetrain, torque and current ratings are the same.
What connector does it use?
The PWM, TTL and CAN builds end in a J30J-15TJL connector, supplied separately. The Modbus build ends in a socket, also with the cable ordered separately.
Is the pulse width table valid for this unit?
No. The microsecond window printed on the inspection sheet belongs to the PWM build of the same servo. This unit is commanded over the serial bus — ask for the command set and register map before writing firmware.
How many can share one bus?
The limit is the address space and the current budget of the shared supply, not the signal pair. Keep the bus ground common with the power ground at a single point.
