DSSERVO DS3240 40 kg·cm Waterproof Digital Servo

Description

DS3240 servo overview

The DS3240 servo by DSSERVO is a high-torque digital servo listed for RC cars and robotics projects. Supplier materials describe it as a waterproof model with an IP66 rating. Its stated input range is 4.8–6.8 V. The supplier also lists 180° and 270° travel options for the 500–2500 μs pulse range; confirm which version is supplied before ordering because travel depends on configuration.

Torque and speed

The 40 kg·cm marking is the supplier’s product-class designation. Use the voltage-specific torque, speed and current values in the specifications below when checking your power supply and controller.

Control and installation notes

The supplied wiring diagram identifies Brown or Black as negative (-), Red as positive (+), and Orange or White as the signal wire (S), depending on the cable version. Match the wiring to the diagram for the exact unit. Use a power source within the stated voltage range and account for the listed stall current. The available rotation angle depends on the servo version and input signal settings, so verify travel and controller compatibility for the intended RC or robotics application.

Contact City of Machinery to confirm the 180° or 270° version, wiring configuration, availability, and quote details for your project.
