It features a custom PCB with the sensor elements and a custom ring magnet to use as a sensor target. The ring magnet is designed to pilot on the flange of any of our 1.125" OD bearings. To install it, glue to any rotating surface or 3D print a custom hub. The magnet can be sensed from either side of the board.
The interface and included cable use a 0.05 in. 2x5 pin header and IDC cable. This lets you plug directly into a Talon SRX speed controller and interface with other popular components for FRC competition use.
The encoder can be acquired as the encoder only, just the magnet, or a bundle which contains the encoder PCB, the ring magnet, the 10 pin SRX data cable and the mounting hardware used in the Swerve and Steer.
Note: As indicated here it is necessary to cut pins 5 and 7 when using this sensor directly with a speed controller to prevent the sensor from restarting intermittently.
Pinout:The Lamprey uses a 10-pin IDC cable arranged in a 5x2.

Seems to be a great solution for measuring rotation on through shafts
We are using this for what most probably are, measuring rotation on a swerve module. The magnets are a little more brittle that expected, we broke one in half on a light press fit and had to order another to replace it. Glad we are close enough for 1-2 day shipping. Thanks!
