Engineers often want to monitor a shaft’s rotational speed but get bogged down trying to get sensors, signal conditioners, cabling, and bulky housings to work together. To solve this dilemma, ...

The SpeedTalker DN (UI) DeviceNet shaft-speed tachometer converts pulse-train frequencies from a wide range of single-ended or differential, single-channel, or quadrature sensors into rpm units.

If you’re into anything even vaguely mechanical on the broad hacking spectrum, you’ve come into contact with things that spin. Sometimes, it’s important to know precisely how fast they are spinning!
