FTC Encoder Selection Guide

Compare magnetic encoders for FIRST Tech Challenge (FTC) robots and choose the right feedback sensor for your drivetrain, odometry pod or mechanism. Start with the output you need, then decide between a protected, shaft-supported encoder and a compact sensor board.

Choose an FTC encoder output

Quadrature encoder output

Tracks rotation across multiple turns. Use it to measure speed, distance and odometry.

Absolute analog encoder output

Reports the mechanism’s single-turn angle immediately, including after startup.

All three use the same MT6701 magnetic sensor. Encoder and Barecoder Micro output 1024 quadrature cycles per revolution—4096 counts with the FTC Control Hub’s 4× decoding. Encoder uses two 6701 ball bearings to support shaft loads.

Which FTC encoder should I choose?

  • Encoder is the ready-to-install choice for a 7 mm hex shaft, protected electronics and supported shaft loads.
  • Nano Encoder is the smallest option when you only need an absolute analog angle and can provide your own mounting.
  • Barecoder Micro is the compact board for custom mechanisms that need both quadrature and absolute analog outputs.
