Thru-Beam Ultrasonic Sensors: Uncompromising Reliability in Detection

Thru-Beam Ultrasonic Sensors, or opposed sensors, represent a high-precision system consisting of separate transmitter and receiver units. This configuration creates a stable acoustic barrier, making them the ideal solution for uncompromising object detection and positioning control, especially in extreme environments.

Operating Principle and Advantages

Unlike diffuse ultrasonic sensors, where the transmitter and receiver are housed in one unit, thru-beam sensors operate on the principle of a light barrier:

1. Transmitter constantly emits ultrasonic pulses.

2. Receiver, positioned opposite, detects this continuous signal.

3. Detection: As soon as any object interrupts the acoustic barrier between the transmitter and receiver, the sensor's output signal changes.

Why Choose Thru-Beam Technology?

• Highest Reliability: Object detection is independent of the object's tilt angle, shape, color, or transparency. The acoustic barrier cannot be "fooled" by mirrored or transparent surfaces.

• Environmental Immunity: Robust protection against false triggers caused by dust, dirt, fog, steam, or humid environments. P+F thru-beam sensors operate reliably where optical barriers quickly fail.

• Long Operating Distances: The ability to create a stable barrier over significant distances, which is crucial for wide conveyor lines or large warehousing systems.

Key Application Areas

Thru-beam ultrasonic sensors are the standard for reliability in the following processes:

• Object Detection in Harsh Conditions: Identification of items moving on conveyors, regardless of the level of air contamination.

• Size and Profile Control: Detecting sagging, tears, or incorrect profiles in wide rolled materials.

• Access Control and Protection: Creating reliable safety zones and monitoring presence in technological openings.

• Object Counting: Accurate counting of production units (especially transparent or non-standard shapes).
