Simple snap-on encoder wheels for TT gearbox motors. These injection-moulded plastic discs attach to the opposite end of the motor shaft from your wheel, letting you measure rotation speed using a photo interrupter sensor to count the ticks as the encoder spins.
An easy, low-cost way to add speed feedback to your TT motor-driven robot — although note that this single-slot design provides speed measurement only, not rotation direction.
Key Features
- Snap-On Fit – Oval notch clips directly onto TT motor shafts
- Speed Measurement – Use with a photo interrupter sensor to count ticks
- Slim Profile – Thin design won't add bulk to your robot
- Pack of 2 – One encoder per motor for a two-wheel robot
Ideal For
- Adding speed feedback to TT motor robot projects
- Odometry and distance tracking
- Closed-loop motor speed control
Package Contents
- 2× TT Motor Encoder Wheels
Jargon buster
Plain-language definitions for the technical terms used above.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- encoder
- An encoder is a sensor that converts the rotation or position of a shaft, knob or dial into electrical signals, reporting movement as incremental steps and direction, or as an absolute position. It is used to track how far something has turned, which matters for precise positioning, speed control, repeatable movement, or using a rotary knob as an input.
