The 350bar S520 rotary sensor is an affordable, durable, high-accuracy sensor designed for Marine and Subsea feedback applications.
The S520, like all Positek® sensors, is supplied with the output calibrated to the angle required by the customer, 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

Positek offers a range of options for its standard sensors. Each sensor is manufactured to suit each customer's preferences. If your requirement is outside the options given below, Positek can modify/ redesign a sensor to suit your specific requirement. Standard options are available as below:
Factory set to any length from ±7.5° to ±80° in increments of 1°. For example, if your application requires 90° measurement, then Positek will manufacture the sensor specifically for this angular range. The sensor will measure 90° however will still rotate through 360°.
