CTR Electronics SRX Mag Encoder Adapter

Last crawled date: 5 years, 10 months ago
The CTR Electronics SRX Mag Encoder is very popular in FIRST robotics, but can be difficult for teams without machining capabilities to use without an adapter because of the geometric tolerances required between the magnet and the encoder sensor.
This is an adapter that allows an assembly to be created which isolates the required magnet to sensor tolerances to 3d printed components, and allows the encoder to be connected to a shaft in need of encoding using surgical tubing or some other compliant means.
It was inspired by what I have read about how some FRC teams use Greyhill optical encoders.http://www.grayhill.com/products/optical-encoders/
Besides the encoder, the adapter requires a 0.375 x 0.875 x 0.280 bearing, a 3/8" e-clip to retain the shaft in the bearing, and two M4x8 machine screws to retain the bearing in the adapter.
