Choose the correct Type

Type What it is Selection guidance
HX-35H Servo Pack The HX-35H serial bus servo with the standard packing-list items. Select this Type when the servo itself is required.
Metal Servo Horn Metal horn accessory pack. This Type is an accessory selection and does not include the HX-35H servo.
Bracket Pack Mounting-bracket accessory selection. This Type is an accessory selection and does not include the HX-35H servo.

Important: Metal Servo Horn and Bracket Pack are separate Type selections. They are not named as standard contents of the HX-35H Servo Pack.

Two serial-bus interfaces

Compatible servos can be connected in series through the two serial-bus interfaces for cleaner routing. HX-35H uses UART serial commands at a default baud rate of 115200. Servo IDs can be set from 0 to 253, with ID 1 as the factory default, so compatible servos can be addressed individually on a shared system.

Image note: the connection illustration is a serial-bus routing example. It does not indicate that multiple servos, a controller or a power supply are included with this listing.

Torque, position range and live feedback

  • Rotation torque: 25kg.cm at 11.1V.
  • Static maximum torque: 35kg.cm at 11.1V.
  • Speed: 0.18 seconds per 60 degrees at 11.1V.
  • Servo-mode range: 0 to 240 degrees; the 0 to 1000 control range corresponds to 0 to 240 degrees.
  • Feedback: position, voltage and temperature, together with angle readback.

Selection note: rotation and static maximum torque are reference values, not recommended continuous-load ratings. Select with a suitable margin for leverage, acceleration, duty cycle, load direction and the complete mechanical design.

Metal gear, dual-shaft construction

The HX-35H combines a metal gear train with a primary plus assistant output shaft. Verify the mounting geometry, output interface, horn clearance and allowable side load against the intended mechanism before installation.

  • 1 x HX-35H serial bus servo
  • 1 x plastic main servo horn
  • 1 x plastic assistant servo horn
  • 1 x 200mm servo wire
  • 1 x screw package

Integration notes

  • Use a regulated 9 to 12.6V supply sized for the complete mechanism. Account for the 3A stalled-rotor current reference when planning wiring, connectors, fusing and power distribution.
  • Assign every compatible bus servo a unique ID before operating a shared serial system. Duplicate IDs can prevent reliable addressing.
  • The official specification lists servo mode and gear-motor mode. Confirm the intended mode before applying power, then test travel, mechanical end stops, linkage clearance and pinch zones at low speed.
  • Use compatible external serial-bus control hardware for setup and operation. Verify connector polarity, supply voltage and communication compatibility before connection.

FAQ

Is HX-35H a 35kg.cm servo?

The official specification lists 35kg.cm static maximum torque at 11.1V and 25kg.cm rotation torque at 11.1V. Use an appropriate safety margin for the real mechanism and duty cycle.

Can HX-35H position through 360 degrees?

No. Servo mode is specified for 0 to 240-degree positioning, with the 0 to 1000 control range corresponding to 0 to 240 degrees. A separate gear-motor mode is also listed.

What feedback is available?

The listed functions include temperature, voltage and position feedback, together with angle readback.

Can several compatible servos share one serial system?

Yes. Assign each servo a unique ID from 0 to 253. The factory default is ID 1 and the default communication baud rate is 115200.

What is the difference between the three Type selections?

HX-35H Servo Pack is the servo package. Metal Servo Horn and Bracket Pack are separate accessory selections; neither includes the HX-35H servo.

Does the Servo Pack include a controller or power supply?

No controller or power supply is named in the HX-35H Servo Pack list. Use compatible external control hardware and a regulated 9 to 12.6V supply.

Does the servo include protection functions?

The official specification lists stall and over-temperature protection. These features do not replace suitable mechanical stops, pinch-zone safeguards, power design or system-level emergency controls.
