Applications and selection notes
Its sonic cone has an aperture angle of only +/-5 degrees, much tighter than the +/-15 degrees listed for the longer-range analog M30 sensor in the same family. A narrow beam is the right tool for looking down a tank nozzle, a narrow chute or a tall silo without picking up the wall, and for picking out one object among several. The datasheet lists adjustable switching hysteresis, teach-in setting of the measuring range and temperature compensation.
Installation hint: aim the sensing face squarely at the target, keep the blind zone clear of obstructions, and avoid mounting next to strong air currents, steam or dust clouds that attenuate sound. Soft or sloping surfaces reflect less energy, so test with the actual material before finalising the position.
Ordering code and what to confirm
The type code starts with RU and the nominal range figure used in the datasheet features, followed by the housing size and the output elements; the letter that follows the range differs between proximity, retroreflective and diffuse variants of the same family, so always order by the full code. Ident number 100039012 identifies this exact version, which the datasheet lists with function Proximity and output NO/NC, PNP/NPN.
Before ordering, confirm the process or ambient temperature, the supply voltage, switching or IO-Link), the required sensing range and blind zone against your target and tank geometry, the connector and cable, and the output type (analog. Values on this page are copied or summarised from the manufacturer datasheet; where the datasheet and a later revision differ, the manufacturer document governs.

About brand
Turck is the German automation company for sensors, connectivity, fieldbus I/O and interface technology. It grew from Hans Turck's engineering office in Mülheim an der Ruhr: in 1965 a chemical plant ordered an isolation amplifier for intrinsically safe circuits, and the first 20 units were built by his brother Werner Turck in Halver. The family-owned Turck group is still headquartered in Mülheim an der Ruhr, with production in Halver and other sites.
Seven Star LLC is an independent supplier in Muscat. We list Turck sensors and I/O devices for machine builders and maintenance teams in Oman and the GCC.

Turck product series
Most of the Turck products here are inductive proximity sensors: threaded M12, M18 and M30 barrels in flush (BI) and non-flush (NI) versions, uprated-range (U) sensors, rectangular CP40 and CP80 housings and BIM magnetic-field sensors for detecting pistons in pneumatic cylinders. The type code describes the sensor; in BI5-M18-AP6X-H1141, BI means flush mounting, 5 is the switching distance in mm, AP6X a three-wire PNP output and H1141 the M12 connector.
Turck also makes RU ultrasonic sensors, PS pressure, TS temperature and LS level sensors, FCI inline flow sensors, the CMVT vibration and temperature sensor for condition monitoring over IO-Link, and fieldbus and Ethernet I/O modules and communication components.
Where Turck sensors are used
Position detection on conveyors, packaging machines, presses and robotic cells; level, pressure and temperature monitoring on hydraulic units and process skids; and vibration monitoring on motors, pumps and fans.
