The Parallax Standard Servo is designed for Parallax's educational kits and is offered here as a replacement part. It is ideal for robotics and basic movement projects. It can hold any position over a 180-degree range and is easily interfaced with any Parallax microcontroller. See our Standard Servo Tutorials for examples.
Parallax Standard Servo Key Features:
- Turns to and holds positions between 0° and 180°
- 38 oz-in torque at 6 VDC
- 4 holes for mounting screws, 2 in each flange
- Easy to interface with any Parallax microcontroller or PWM-capable device
- High-precision gears made of POM (polyacetal) resin make for smooth operation with no backlash
- Weighs only 1.48 oz (42 g)
This is the digital version of the Parallax Standard Servo, released in summer 2022. It is designed to drop-in replace the previous analog version for Parallax educational kits. Applications such as adding this device to a digital bus are not supported. For documentation of this servo’s previous analog version, see the product guide version 2.2 available from the Downloads section.
- Gear material: POM (polyacetal)
- Spline: 3F 25-tooth
- Weight: 1.48 oz (42 g)
- Torque: 38 oz-in @ 6 V
- Speed: 0.19 sec/60 deg @ 6.0 V, 0.23 sec/60 deg @ 4.8 V.
- Supply voltage: 4 to 6 VDC
- No load voltage/current: 100 mA at 6 VDC in motion, 20 mA at resting state. *
- Communication: pulse-width modulation (50 Hz)
- Operational pulse control signal range: 500 µs to 2530 µs +/-20 µs
- Approximate angular responses to pulse widths:
(620 µs, 1520 µs, 2420 µs) maps to (0°, 90°, 180°) with angles increasing from clockwise to counterclockwise
- Approximate internal mechanical limits: -10° and 190°
- Dimensions: approx 2.2 x 0.8 x 1.6 in (5.58 x 1.9 x 4.06 cm) excluding servo horn
- Operating temperature range: 14 to 122 °F (-10 to +50 °C)
- Under certain load conditions, current can briefly increase to 500 mA or more, and the supply should be chosen to accommodate this. Servo current draw can spike while under load. Be sure that your application's power supply and voltage regulator is prepared to supply adequate current for all servos used. Do not try to power this servo directly from a BASIC Stamp module's Vdd or Vin pins; do not connect the servo's Vss line directly to the BASIC Stamp module's Vss pin.
