The Banner PIRS1X166UMPMAL is a durable and versatile fiber optic sensing solution designed to deliver accurate, long-range detection in demanding industrial applications. Built with plastic opposed array fibers and packaged in a rectangular housing, this model is supplied as a pair for reliable emitter/receiver performance when used with Banner’s advanced DF-G3 amplifiers.

The unit operates in an opposed array sensing mode, where one fiber optic cable transmits light while the other receives it. When an object interrupts the light path, the system registers detection. The array design provides enhanced detection across the full beam area, making it particularly effective for counting small objects, detecting irregular shapes, or monitoring multiple parts simultaneously as they pass through the sensing field. This ensures consistent performance even in high-speed production environments.

Offering a maximum sensing range of over 3 m and up to 5 m when paired with DF-G3 amplifiers, the PIRS1X166UMPMAL provides long-distance detection capability while maintaining accuracy and repeatability. This extended range makes it ideal for large conveyors, wide material handling systems, and applications where there is significant space between the sensor and target.

Constructed from plastic fiber optics, this model offers flexibility, durability, and cost-effectiveness. Plastic fibers are resistant to bending and are easy to route through tight machine layouts, ensuring convenient integration into complex automation systems. They also provide reliable performance in applications where repeated adjustments or repositioning may be required, such as flexible production lines.

The rectangular housing style ensures stable mounting and simple alignment, while the paired design reduces setup complexity by ensuring both emitter and receiver are optimally matched. This configuration not only simplifies installation but also ensures long-term accuracy and consistent operation, reducing downtime and maintenance requirements.

With a quantity of two fibers included, the PIRS1X166UMPMAL provides a complete opposed sensor solution, eliminating the need to source separate components. The matched pair ensures optimal optical performance, which is especially critical in high-speed or high-precision applications.

Practical applications include part counting on conveyors, label detection, monitoring small components in assembly lines, and verifying material flow in packaging and bottling lines. The opposed array design provides superior performance in scenarios where diffuse or retroreflective sensing may struggle due to irregular surfaces, variable colours, or low reflectivity.

In summary, the Banner PIRS1X166UMPMAL Fiber Optic Sensor Pair combines opposed array sensing, long-range detection of 3–5 m, durable plastic fiber construction, and stable rectangular housing design into a dependable and flexible sensing solution. When paired with a DF-G3 amplifier, it delivers the accuracy, reliability, and adaptability required for today’s fast-moving and complex industrial automation systems.
