Using it in the field
IO-Link means the head plugs into a standard master port and sends the tag data as 32-bit process data, so RFID can be added without a dedicated interface module. Parameterisation is possible via IO-Link, PACTware or a parameterisation tag. The compact M18 housing fits the small-parts tooling and carrier tracking that the larger Q80 head cannot reach, but the shorter read range means the tag must pass close to the active face. The datasheet gives a minimum cycle time of 14.4 ms and a transmission rate of 26.5 kbps, which together set how quickly tag data can be exchanged while a carrier passes the head, so allow conservative transport speeds. Protection class is IP67 and the ambient range is -25 to +70 C, with non-flush mounting listed, meaning the active face needs a metal-free zone around it.
Installation hint: mount the head so tags pass through the read zone at the speed and distance you tested, keep the face clear of surrounding metal, and separate the head from other HF equipment to avoid interference. Fix the cable and connector so vibration does not stress them.
Ordering code and what to confirm
TN is the Turck HF RFID read/write head family; the housing token (Q80, M18, M30) matches the design row (Threaded barrel, M18 x 1), IOL marks IO-Link versions and EX marks the version with hazardous-area marking. Ident number 100000974 identifies this exact head.
Points to confirm with us before ordering: any hazardous-area approval conditions, the interface (IO-Link or 4-wire), the tag type and read/write distance for your application, the supply voltage, and mounting space and metal environment. Everything in the table comes from the datasheet as published, so the maker document is the final reference.

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.
