About the S520 Rotary Inductive Position Sensor

The 350 Bar S520 rotary sensor is an affordable, durable, high-accuracy sensor designed for marine and subsea feedback applications.

The S520 sensor is supplied with the output calibrated to the angle required between 15 and 160 degrees and with full EMC protection built in. The sensor provides a linear output proportional with angle of rotation. There is a machined registration mark to identify the calibrated mid point.

It is particularly suitable for OEMs seeking good sensor performance for arduous applications such as subsea ROVs where long term reliability and excellent sealing is important.

Overall performance, repeatability and stability are outstanding over a wide temperature range.

The S520 has long service life and environmental resistance with a rugged 316 stainless steel body and shaft, The flange mounting makes the sensor easy to install. There are a range of electrical options. Environmental sealing is to IP68 350Bar, 3500 msw, 5000 psi
