Overview

The AndyMark HexBore Encoder is a robust, multi-output rotary position sensor designed for direct mounting on hex shafts. It supports quadrature, absolute PWM, and absolute analog outputs, making it flexible for both closed-loop motor control and absolute position sensing across FRC, FTC, and general robotics applications.

With a wide supply voltage range and factory-calibrated zero alignment, the HexBore Encoder is ideal for mechanisms that need reliable position feedback without couplers, belts, or additional alignment steps.

Use this page to understand what the encoder is good for and how to get started. Detailed electrical limits, pinout, and mechanical drawings live on Specifications. Wiring examples and software samples live on Examples.

When to use this encoder

  • Measuring shaft position on arms, elevators, wrists, or turrets.

  • Providing absolute position on boot (via PWM or analog output).

  • High-resolution quadrature feedback for motor controllers or motion profiling.

  • Applications where direct hex-shaft mounting simplifies mechanical design.

hashtag
What this encoder is not

  • It’s not a magnetic through-bore encoder for round shafts without adapters.

  • It’s not a high-level smart encoder with onboard filtering or bus communication.

hashtag
Highlights (at a glance)

  • Three output modes: Quadrature (A/B), Absolute PWM, and Absolute Analog.

  • 4096 counts per revolution quadrature resolution (1024 PPR).

  • 12-bit absolute resolution (4096 positions per revolution).

  • Wide supply range: 3.3 V – 16 V with 3.3 V logic (5 V tolerant).

  • Hex-shaft mounting with factory-aligned zero position.

  • Locking 4-pin JST-PA connector with included FTC and FRC cables.

hashtag
Typical integrations

  • Mount directly on an arm or wrist shaft to retain position after power cycles.

  • Pair quadrature outputs with motor controllers for closed-loop velocity or position control.

  • Use absolute PWM or analog output for homing-free startup.

  • Install on swerve modules or rotating mechanisms where compact, coaxial sensing is required.

Best-practice tips

  • Choose the right output:

    • Use quadrature for fast control loops.

    • Use PWM or analog when absolute position on startup matters.

  • Mind cable strain: secure the cable near the connector to avoid fatigue on rotating assemblies.

  • Check zero alignment: the encoder is factory-calibrated to the hex notch—verify orientation during assembly.
