Key Features

Long Sensing Range: Offers a substantial measuring range of up to 2 meters, making it ideal for applications where the target is distant or where the sensor needs to be mounted further away from the process.

Dual Digital Outputs: Equipped with one PNP (sourcing) and one NPN (sinking) output. This allows the sensor to directly connect to both sinking and sourcing input modules without additional circuitry, simplifying integration.

Programmable Switching Window: The two outputs can be independently configured via push-button teach-in to define a precise switching window (e.g., an object present between distance X and Y). Each output can be set to Light or Dark operation (NO/NC).

Strong Environmental Immunity: Ultrasonic technology is immune to the target object's color, transparency, or surface finish. It reliably operates in challenging conditions filled with dust, mist, light vapors, or ambient light that would disrupt optical sensors.

Potentiometer Adjustment: Features potentiometers for fine-tuning parameters like response time and sensitivity, allowing for optimization in complex applications.

Robust Housing: Housed in a rectangular, industrial-grade plastic housing with an IP67 protection rating, making it resistant to dust and temporary immersion, suitable for harsh environments.

5. Typical Applications

The UP56-213118's long range and robust digital outputs make it perfect for a wide array of industrial monitoring and control tasks.

Pallet Monitoring: Detecting the presence or absence of pallets on high racking, in storage areas, or at the end of a conveyor line.

Large Object Detection: Detecting vehicles, large bins, or containers in logistics and assembly areas.

Level Monitoring: Monitoring the fill level of bulk materials (e.g., grain, plastic pellets, sand) in large bins or silos from the top down.

Roll Diameter Measurement: Measuring the decreasing diameter of large rolls of material (e.g., paper, textile, foil) on winding machines.

Parking Guidance Systems: Detecting vehicle presence in parking spaces or at garage entrances.
