DYS Waterproof 35kg 8.4V Digital Servo, CNC Aluminium Case (IP67)

A 35 kg·cm high-voltage digital servo in a CNC-machined aluminium case, sealed to IP67 against dust and water. It is built for heavy, exposed linkages: payload-release mechanisms on drones, large fixed-wing control surfaces, robotic joints and RC steering. Choose the 180° or 270° travel version.

Key features

• Torque climbs from 28 kg·cm at 6 V to 31 kg·cm at 7.4 V and 35 kg·cm at 8.4 V
• Full metal gear train running on two ball bearings
• Aluminium alloy case adds rigidity and draws heat away during sustained load
• IP67 sealing for mud, rain and brief immersion
• Standard PWM control over a 500–2500 µs pulse range with a 2 µs dead band

Specifications

• Torque: 28 / 31 / 35 kg·cm at 6 / 7.4 / 8.4 V
• Speed: 0.20 / 0.14 / 0.11 s per 60° at 6 / 7.4 / 8.4 V
• Idle current: 270 / 320 / 350 mA at 6 / 7.4 / 8.4 V
• Running current: 2.2 / 2.8 / 3.2 A at 6 / 7.4 / 8.4 V
• Travel: 180° or 270° (by variant)
• Gears: Full metal, 2 ball bearings
• Case: CNC aluminium alloy
• Ingress protection: IP67
• Dimensions: 40 x 20 x 40.5 mm
• Weight: 78 g
• Lead: 300 mm, 22AWG (brown negative, red positive, yellow signal)
• Operating temperature: -20 to +60 °C

Power it from a 2S LiPo (8.4 V fully charged) or a 6–8.4 V BEC good for about 3.2 A per servo; a 5 V receiver or flight-controller rail is below its 6 V minimum. Full travel needs the 500–2500 µs signal, so a radio limited to 1000–2000 µs moves it through roughly half its range.
