Common or uncommon sensors used in FRC

Polarized retro reflective photoeyes.
Banner DS18VN6LP about $50 each, need polarized reflectors.
Banner BRT-35DM refectors. $7 each
Banner SMB18A mounting bracket.

In industry polarized are used, as they are less likely to be fooled by shiny objects. Really not a problem with rebound rumble balls or discs, but may be in the future.

I like these better than the AB ones that came in the kit of parts, Logomotion, as they seem to be more stable at lower battery voltages than the AB units. Logomotion year, they allowed them to be wired to 24vdc supply, I did not see that allowed rebound rumble, or ultimate assent.

534-1-1-503 Spectrol 50K 10 turn POT, this is just something we had on the shelf from job, used as angle sensor.

If using industry stuff, you need to look for the 10v dc range for lower end, and NPN switching for the digital side card. NPN is not typically used in the US industry, so you may need to order.

I work in industrial controls, so TORC is lucky to have these donated to the team.
