Specifications:

  • Stroke: 140mm
  • Length: 208mm
  • Weight: 96g
  • Extended length: 348mm
  • Gear Ratio: 150:1
  • Speed (no load): 6mm/s
  • Max Force: 190N
  • Stall Torque: 325N
  • Wire length: 340mm
  • Connector: 2.54mm Dupont 3-Pin Female
  • Control Signal: PWM
  • Frequency: 50 HZ
  • Voltage: 6V

Pulse Width Range

The linear servos have a different pulse width range than that of normal servos. The range of a normal servo is generally 500μs. to 2500μs. The linear servo has a standard range of 900μs to 2100μs. However, due to tolerances in control, this range generally needs to be manually calibrated per linear servo.

Actuator

At full retraction, the pulse width should be around 900μs. Observational measurements have found this value to be between 850μs and 1000μs.

At full extension, the pulse width should be around 2100μs. Observational measurements have found this value to be between 1890μs and 2150μs.
