Product catalog summary

Introduction
Baumer's ultrasonic sensors are compact, robust, and versatile, designed for demanding applications. They operate by emitting ultrasonic bursts that reflect off objects and are received back by the sensor, providing digital or analog outputs. Unlike optical sensors, they are unaffected by color, transparency, or reflectivity, making them ideal for harsh environments.

Types of Ultrasonic Sensors

Distance Measuring Sensors: Provide absolute position information, suitable for level detection and stack height control.
Proximity Sensors: Detect objects within a set range, unaffected by surface properties.
2 Point Proximity Switches: Offer precise detection at two points.
Retro-reflective Sensors: Use a fixed reflector to detect objects, ideal for sound-absorbing materials.
Through Beam Sensors: Consist of an emitter and receiver, used for fast-moving or transparent objects.

Applications
Ultrasonic sensors are used in various applications such as height measurement, liquid level detection, and distance detection in confined spaces. They are particularly useful in environments with dust, smoke, or vapors.

Design and Functionality
Ultrasonic sensors use a sonic transducer for alternating transmission and reception of sound waves. The time between emission and reception is proportional to the object's distance. They feature a digital output and can be adjusted using a potentiometer or Teach-in technology.

Mounting and Operation
Proper mounting is crucial for optimal performance. Sensors should be spaced appropriately to avoid interference. The LED indicator assists in setup by showing signal strength and output state.

Innovations and Custom Solutions
Baumer focuses on miniaturization, precision, and robustness. They offer customized solutions for unique applications, working closely with customers to meet specific needs.

Conclusion
Baumer's ultrasonic sensors are reliable, precise, and adaptable, making them suitable for a wide range of industrial applications. Their innovative design and robust performance ensure they meet the demands of modern automation.

All-round talents. Most ultrasonic sensors are based on the principle of measuring the propagation time of sound in air. Packages of ultrasonic sound, so-called bursts, are emitted by the sensor, reﬂected by an object and received again by the sensor. The integraged transducers with sonic frequencies far beyond the range of human hearing, constantly switch to and fro between emission and reception. The returned echo signals are evaluated by the integrated electronics of the sensor. Depending on the sensor type, the information is provided at the output either as digital or analog signals.
