The REV Through Bore Encoder is specifically designed with the end user in mind, allowing teams to place sensors in the locations closest to the rotation that they wish to measure. This rotary sensor measures both relative and absolute position through its ABI quadrature output and its absolute position pulse output. Mounting an encoder has never been easier with a 1/2" Hex Through Bore paired with the molded mounting holes which allow users to quickly place this encoder on the object they want to measure. Using one of the included inserts allows for the 1/2” hex to convert to 3/8” hex, 5mm hex, or 1/4” round for additional flexibility.

Features

Incremental and absolute magnetic encoder a

Built-in magnet



Quadrature output - A, B, and Index



Absolute output - Pulse Width (Duty Cycle)



Broadcom AEAT-8800

Factory calibrated zero-position b

Zero calibrated to notch in case

Through-bore design

Easily mounted to any shaft



Bore inserts



1/2" Hex (default)





3/8" Hex

Mounting holes

Holes spacing matches common FRC gearboxes and chassis

a. The FTC Control System only supports Incremental Encoder input through the motor encoder ports at this time. Absolute pulse input is not supported.

b. Do not disassemble the sensor. Disassembling the Through Bore Encoder will dereference the zero position with the physical case notch. It is not possible to recalibrate the zero position as it is permanently saved inside the sensor at the factory.
