This is the 1/2 in. hex steel output shaft for the Toughbox® series gearboxes when used with the AM14U5 prior to 2023.
The AM14U5 uses round bearings in the outside plate rather than hex bearings. As a result, this shaft differs from previous AM14U output shafts by having a round portion at the end.
If attempting to use this shaft with the SRX Magnetic Encoder (am-3445), the SRX Magnetic Encoder Mounting Hardware Kit (am-3565) will be needed. The hardware allows for proper spacing of the encoder from the shaft magnet on Toughbox® Series Gearboxes. You will also need to remove the steel pin and replace with a magnet such as am-3505
