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.

This product includes two 1.25 inch long half inch hex couplers. This product has been verified to clamp all the various standards of 1/2" hex, rounded hex and AM churro with significant clamping force.

• 1.25" long overall - shortest hex coupler on the market.
• Split half design allows you to easily remove or add the coupler back on - great for mechanisms that might require maintenance or replacement.
• Each coupler includes four 3/8" long 6-32 threaded black oxide steel bolts. These bolts use a 7/64" driver to prevent easily stripping the bolt heads out.
• .1 ounces or .0625 pounds, black anodized 6061 aluminum.

Half inch hex hubs are often used to transfer motion between components in competition robots. This hub includes a thicker quarter inch flange that allows for tapping 10-24 / 10-32 holes or drilling and tapping to 1/4-20 sized holes. The Thrifty Hub is offered as a blank hex hub to teams to do further machining or leave stock as-is.
