What rugged sensors do you use?

To name a few, the parallax ultrasonic modules are very robust and lasted even when perched atop the first extension of our elevator. Also, the US digital analog encoders were much more durable than expected despite their small size.

Above all, if you ever need a multi-turn analog pot, Vishay's are unbelieveably durable... we had one accidentally take the torque of the elevator comming down when a set screw was set wrong, and amazingly it still worked!
