Novotechnik introduces RFC4800 Series of touchless angle sensors with J1939 CANBus interface

June 19, 2018 - Novotechnik, U.S. introduces the RFC4800 Series of touchless angle sensors measuring angular position up to 360°, revolution counter and speed—with J1939 CANBus interface in addition to CANopen.

Features include programmable zero point offset, measurement averaging and sign of rotational direction. RFC4800 Series has a resolution of 14-bits across 360°, repeatability of 0.36° and independent linearity of ±0.5% of full scale.

J1939 CANBus provides a different feature set than CANopen. The J1939 protocol has transfer fixed at 250 kbit/s and defines shielded twisted pair for cables. While CANopen has a range if data transfer rates allowed. J1939 has peer-to-peer or broadcast signaling and fixed messages rather than configurable. There are other differences too.

Other RFC4800 Series output interfaces include analog voltage and current, as well as digital outputs options—IO-Link, SSI, SPI, and incremental.

Single and multi-channel versions of the RFC4800 Series are available. Sensors are sealed up to IP69K and operating temperature range is -40 to +125 °C. Mean time to failure is 76 years.
