Product Overview & Technical Specifications
Confirmed model data and purchasing relevance
LS-09M A copper-gear digital servo with a listed 13.5±0.5g weight, a 90°±10° operating travel angle and a 210° mechanical limit angle, with overload, over-current and over-voltage protection marked in the record.
Procurement relevance: The LS-09M record lists the following values, taken as written in the approved product record. The record does not list a spline or shaft diameter for this model, so that row is omitted rather than estimated. A buyer can therefore size the mechanism, the supply and the mount from listed values instead of from estimates.

Buyer Considerations
Five decisions that most often cause a mismatch
The full parameter set is in the specification table in module 01 - the points below are the decisions rather than a second parameter list.
- Gear material. The record marks the gear material as metal (copper). This is the difference from the plastic-gear unit in the same range, which lists the same electrical figures at a lower listed weight.
- Weight. The listed weight is 13.5±0.5g. Use that figure for payload and packaging calculations rather than any number carried in the model designation.
- Supply. The listed operating voltage is 4.8~6V DC, with stall current of ≤700mA at 4.8V and ≤800mA at 6.0V. Check your rail holds voltage under load.
- Protection. The record lists overload, over-current and over-voltage protection mechanisms. Protection reduces the chance of damage in a fault condition; it does not raise the load rating, and the stall torque figures remain the limit.
- Travel. The listed operating travel angle is 90°±10° and the listed mechanical limit angle is 210°. The travel figure is what the unit is specified to command; the limit angle is a mechanical stop, not an operating range.

Why Consider the LS-09M
What the confirmed specification actually gives a buyer
- A copper gear train, as marked in the record, for builds where the load exceeds what a plastic-gear unit in the same range is listed to deliver.
- Overload, over-current and over-voltage protection marked in the record, which is a documented fault-handling characteristic rather than a marketing claim.
- A listed angle precision of ≤1°, so repeat positioning is repeatable on linkages.
- A listed no-load current of ≤150mA at 4.8V and ≤170mA at 6.0V, useful when several axes share one supply.
- A 210° mechanical limit angle behind a 90°±10° operating travel angle, giving the mechanic a defined stop outside the commanded range.
- Consistent supply terms: the standard MOQ for this servo line is 100 pcs, and OEM/ODM requests are handled as project-specific enquiries.

- Target quantity, and whether this is a repeat production run or a new build.
- The application - RC or UAV platform, and the axis or mechanism the servo drives.
- The controller you intend to use and the signal output type it drives.
- The supply voltage and how it is generated.
- The output spline and shaft you need to mate with.
- The mechanical envelope available, in millimetres.
- Packaging, labelling and shipping requirements.
Feasibility, scope and commercial terms are confirmed for the specific project rather than published as standard claims. Send project details to sales@linqdom.com.

Engineering & Compatibility
Checks to complete before integration
Compatibility with a particular controller or system is not implied by this page - verify the exact configuration. The checks worth completing before integration are:
- Voltage. The record lists an operating range of 4.8~6V DC. Provide a regulated rail in that range able to source the listed stall current of ≤700mA at 4.8V (≤800mA at 6.0V).
- Current budget. Static current is listed as ≤8mA at 6.0V and no-load current as ≤150mA at 4.8V (≤170mA at 6.0V). Use the static figure for quiescent sizing and the stall figure only for short peak checks.
- Signal. The listed communication is PWM with a 500~2500μs pulse width range and a rotating direction of CCW. Confirm the controller signal output type and command timing.
- Mechanical. The listed weight is 13.5±0.5g, the operating travel angle is 90°±10° and the mechanical limit angle is 210°. The record does not list a spline or shaft diameter for this model, so confirm the output interface with the supplier before committing a horn or arm.
- Protection scope. The listed overload, over-current and over-voltage protection is a fault-handling characteristic. As general engineering guidance, it does not extend the stall torque figures and should not be used to justify a load beyond the listed rating.

Frequently Asked Questions
B2B engineering and purchasing questions
|
Is the LS-09M a metal gear or a plastic gear servo?
The record marks the gear material as metal (copper). That is the primary distinction from the plastic-gear unit in the same range. The two models list the same electrical figures — 4.8~6V DC, static current ≤8mA at 6.0V, no-load current ≤150mA at 4.8V and ≤170mA at 6.0V, stall current ≤700mA at 4.8V and ≤800mA at 6.0V, stall torque ≥1.3kgf·cm at 4.8V and ≥1.5kgf·cm at 6.0V, a 500~2500μs pulse width range, a 90°±10° operating travel angle, a 210° mechanical limit angle and ≤1° angle precision — and differ in gear material and in listed weight, 13.5±0.5g against 9±0.5g. As general engineering guidance, choose on the load your mechanism actually applies. |
What is the weight of the LS-09M digital servo?
The record lists the weight as 13.5±0.5g, and that is the figure to use for payload, packaging and shipping calculations. As general engineering guidance, treat a weight appearing in a model designation as a series label rather than a measurement unless the record itself states a weight, and confirm the figure against the record before quoting it in a specification. |
|
What protection does the LS-09M have?
The record lists overload protection, over-current protection and over-voltage protection as marked mechanisms. This is a fault-handling characteristic and should be understood as such: it does not raise the load rating, and the listed stall torque of ≥1.3kgf·cm at 4.8V and ≥1.5kgf·cm at 6.0V remains the limit. As general engineering guidance, size the mechanism against its continuous load and treat protection as a secondary safeguard. |
What stall torque does the LS-09M provide at 6V?
The record lists stall torque of ≥1.3kgf·cm at 4.8V and ≥1.5kgf·cm at 6.0V. These are stall values at the two ends of the listed supply range, not continuous working figures. As general engineering guidance, size the mechanism against the continuous load you actually apply, with margin, and use the stall figure only as a peak limit. |
|
What is the difference between 90°±10° travel and the 210° mechanical limit?
The listed operating travel angle is 90°±10°, which is the range the unit is specified to be commanded through. The listed mechanical limit angle of 210° is a physical stop beyond the commanded range. They describe different things and neither is a continuous-rotation claim. As general engineering guidance, write the requirement against travel, and treat any mechanical limit as a fixed physical constraint of the mechanism rather than a usable range. |
What is the MOQ for metal gear digital servos, and what does an OEM enquiry need?
The standard MOQ for this servo line is 100 pcs. For OEM or ODM enquiries send the target quantity, the application and platform, the controller and its signal output type, the supply voltage and how it is generated, the output interface you need to mate with, the mechanical envelope available, and packaging and shipping requirements. Note that this model’s record does not list a spline or shaft diameter, so include a request for that specification if your build depends on it. LINQDOM is a Shenzhen-based B2B supplier with OEM/ODM sourcing and customization support, so the request is reviewed as a project. Send details to sales@linqdom.com. |
