The Keyence FU-R67TG is a threaded, hex-shaped active receiver fiber unit engineered for high durability and stable performance in demanding industrial environments. Built with a stainless steel body and designed for secure threaded installation, the FU-R67TG provides reliable detection performance while withstanding harsh conditions such as vibration, mechanical stress, and exposure to challenging environments.

One of the core features of the FU-R67TG is its M6 threaded, hex-shaped design, which ensures a secure and repeatable installation. This threaded structure allows the fiber to be mounted directly into machine frames or brackets with precision, minimising the risk of misalignment due to vibration or impact. The hexagonal body further simplifies tightening, ensuring consistent positioning in automation setups where reliability is critical.

The FU-R67TG is supplied with a 1 m (3.3′) fiber length, which is non-cuttable. This fixed length guarantees the integrity of the fiber unit, preserving its internal optical alignment and stainless-steel protection. By preventing modifications, the design ensures consistent sensing performance over its service life. This makes it ideal for applications requiring long-term stability in demanding environments.

Constructed with stainless steel, the FU-R67TG provides superior durability compared to standard fiber units. The material protects against abrasion, impacts, and environmental factors such as oil or dust, making it particularly suitable for use in machining centers, automotive production, and other heavy-duty applications. Stainless steel construction also extends the sensor’s lifespan, reducing the frequency of replacements and lowering maintenance costs.

Despite its rugged build, the FU-R67TG offers installation flexibility with a minimum bend radius of R10 mm (0.39″). This allows the fiber to be routed efficiently through tight spaces or complex machine assemblies without compromising optical performance. The combination of flexibility and durability ensures the sensor can be adapted to various layouts while maintaining long-term reliability.

As an active receiver fiber, the FU-R67TG is designed to capture transmitted light from paired emitter fibers, providing stable through-beam detection. This makes it particularly effective in applications requiring reliable object detection, such as part presence confirmation, counting, or position verification in high-speed production lines.

Applications for the FU-R67TG include detection tasks in metalworking and machining environments where cutting fluids and vibration are present, automotive manufacturing lines where ruggedness is essential, and packaging systems requiring secure, stable sensing over long operation periods.

In summary, the Keyence FU-R67TG is a durable, stainless-steel active receiver fiber unit featuring an M6 threaded hex-shaped design, fixed 1 m fiber length, and tight bend radius. It is built to provide stable and reliable detection in harsh industrial environments where vibration, abrasion, and mechanical stress are common. For manufacturers seeking a robust sensing solution that balances strength, precision, and flexibility, the FU-R67TG is an excellent choice.
