These crowned roller pulleys are designed to fit over 1.25" OD tubing. They are made from 70A durometer TPE and are great for keeping flat urethane belting centered on your tubes or for simply intaking game pieces using the rollers themselves.

Holes are included for 5/32 rivets that can be used for retention on tubes. Rivets nest nicely within the TPE material, leaving the rivet head slightly below the rest of the roller material.

The Thrifty Absolute Magnetic Encoder was designed to provide teams a lower cost option for absolute position sensing. Simply plug the included 3-wire PWM style cable into your controller of choice and read the included magnet's absolute position. This device can connect directly to the RoboRIO as well as the REV Spark Max or CTRE Talon SRX.

Encoder Revision Updates Include -

• Switched to through hole connector to improve strength and assembly
• Cases are produced in ESD safe materials
• A J2 jumper spot has been added. Simply solder the jumper spot and the encoder will run in 3.3v mode. See the user guide for more details.
