Members of a series of rotary and linear position sensors comply with the SAE J1939-based CAN protocol, which they use to transmit 16-bit absolute position data. The sensors do not require perfect alignment to operate properly.
Linear transducers in the series include the PT1CN, PT51CN, PT8CN, and PT9CN. The units are available in full-stroke ranges from 2 in. to more than 140 ft. Rotary transducers include the RT8CN and RT9CN, come in measurement ranges from 45 degrees to up to 200 turns, and are said to withstand harsh environments.
The series is easy to install, thanks to a standard five-pin microconnector that attaches directly to the CAN bus. A rugged, high-precision conductive plastic potentiometer sits at the core of each sensor. Sensors are addressable via a node address (MAC ID) that can be set over the network or by internal switches. Internal switches also set the baud rate for 124, 250, or 500 Kbaud. Custom firmware applications are available for OEMs.
