Description

BUS M18M1-XB-02/015-S92G – ultrasonic sensor

Ultrasonic sensor BUS M18M1-XB-02/015-S92G uses the reflection of sound pulses for non-contact evaluation of an object or distance. The declared working range is 25–250 mm; below its lower limit, measurement reliability cannot be assumed. Unlike the optical principle, the colour of the object is not decisive, but ultrasonic measurement is affected by the shape, inclination and acoustic reflectivity of the target.

What an ultrasonic sensor is and how it works

Ultrasonic sensor emits short sound pulses at a frequency above the limit of human hearing. It evaluates the distance or presence of the target from the delay of the reflection from the object. It does not require the object to be magnetic or metallic and, unlike optical sensors, is much less affected by the colour or transparency of the surface. It is therefore also used for plastics, packaging, bulk materials and, with suitable mounting, for level monitoring.

What the range means for this version

The specific model BUS M18M1-XB-02/015-S92G measures in the range 25–250 mm. Objects at a distance less than 25 mm lie in the area close to the blind zone; the maximum declared distance is 250 mm. A shorter measuring range is suitable, for example, for detecting small objects close to the sensor.

Where this model is used

Conveyor lines: detecting the presence of a product or package without mechanical contact.
Kontrola polohy: measuring the distance and height of an object within the available range.
Handling and packaging: detection of plastic or transparent packaging depending on measuring conditions.

How the measurement information gets into the PLC

Analogue current 4–20 mA transmits continuous distance information. For the voltage variant, use the appropriate voltage input; for the current variant, a PLC current input. An analogue sensor is not a direct replacement for a conventional PNP/NPN switching sensor without further wiring.

How to choose and correctly use this variant

Measuring range: 25–250 mm; observe the minimum distance and the upper limit of the range.
Output: Analogue current 4–20 mA.
Connector / cable: Connectors, connector M12 × 1, 5-pole; choose compatible accessories.

Important note for application design

Ultrasonic measurement has limitations: soft or inclined surfaces can absorb sound or reflect it away from the sensor. Foam, turbulence, strong air flow and simultaneous sensors can worsen measuring conditions. The manufacturer states the range for certain conditions; it is advisable to test the actual application.
