The sensor is offered in six standard measuring ranges with angles from 0 - 60 to 360 degrees with unrestricted rotation. Range resolution is 12-bit across a 4-20 mA output with linearity specified at 2% at = 90 degrees; repeatability is 0.2 degrees and update rate is 5 kHz.

Single and dual redundant versions are available and the non-contacting NOVOHALL Hall Effect measurement technology yields a 100 million movement life even under the most arduous shock and vibration conditions.

Redundant versions can be validated to ISO 13849 PL-d functional safety standard. Type E1 approval has also been obtained from the Federal Motor Transport Authority in Germany. (KBA). The heavy-duty RSX-7900 is also available with a CANopen interface.

The durable sensor design includes a fully sealed anodized aluminium housing with a stainless steel shaft for enhanced corrosion protection with salt and spray resistance. Axial and radial shaft loading is up to 300N thanks to a double row angular contact ball bearing design. The compact 70mm diameter sensor has a nominal length of only 35mm and is available with a wide choice of shaft styles for maximum installation flexibility.

The RSX-7900 angle sensor operates from a generous 9 to 34Vdc input providing scope for 12V and 24V mobile vehicle systems and further flexibility for electrical connection includes cable gland and M12 connectors.
