Position sensors provide high reliability

Contactless inductive technology enables RSE 1500 rotary position positions to offer high accuracy and repeatability with exceptional reliability.

Macro Sensors has released contactless, fractional-turn, rotary position sensors that provide an absolute output proportional to shaft rotation.

The RSE 1500 rotary RVDT position sensors are suitable for measuring the angular displacement of rotating elements such as quarter-turn ball and butterfly valves, air flow dampers, mail sorters and diverter gates used in packaging and postal sorting machinery.

Units are also useful for other limited-rotation applications requiring high reliability.

These applications include pedal position sensing for mobile equipment such as lift trucks, stackers, golf carts and lawn tractors, and throttle lever position sensing in boats, cranes and articulating-arm utility service vehicles.

Although their shafts can rotate a full 360 degrees, the RSE 1500 sensors measure shaft angle position over a nominal range of 120 degrees.

Units can operate in 0 to 30, 60, 90 or 120 degree rotation ranges.

Contactless inductive technology enables these rotary position positions to offer high accuracy and repeatability with exceptional reliability.

Units exhibit a linearity error of less than 0.10% of full range output while operating over temperatures from -20 to 85C.

The RSE 1500 rotary RVDT position sensors use built-in electronics to offer a DC input/output configuration.

Operating from a nominal 24V DC power supply, units supply a true 0 to 10V DC output.

The absolute output characteristic makes the RSE 1500 series superior to incremental output sensors like optical encoders that lose their position information in the event of a power failure.

Built for long life, units are enclosed in a 1-1/2in diameter anodised aluminium shell and have a 0.250in stainless steel shaft running in high-performance ball bearings.

Units are also environmentally IP66-sealed.
