Power HD Micro Digital Servo HD-1581HB

The HD-1581HB digital servo from Power HD is a micro servo with digital control electronics for increased performance. The output shaft is supported by a ball bearing, and some of the gears are metal for increased durability. Servo horns and associated hardware are included.

Key specs at 6 V: 0.16 sec/60°, 36 oz-in (2.6 kg-cm), 12.3 g.

The HD-1581HB is a great high-performance actuator for small mechanisms. Digital electronics coupled with a ball bearing give this servo a distinct edge over analog micro servos. This is the strongest micro servo we carry. The pictures below show the metal gear train and the hardware included with this servo (minus the two included mounting screws).

Though not shown in the above picture, two mounting screws are also included.

FAQs

What are the three wires coming out of my servo?

Most standard radio control servos (and all RC servos we sell) have three wires, each a different color. Usually, they are either black, red, and white, or they are brown, red, and orange/yellow:

• brown or black = ground (GND, battery negative terminal)
• red = servo power (Vservo, battery positive terminal)
• orange, yellow, or white = servo control signal line

Please check the specs for your servo to determine the proper power supply voltage, and please take care to plug the servo into your device in the proper orientation (plugging it in backwards could break the servo or your device).
