Ultrasonic sensors can be used as contact-free devices in many areas of automation. They are employed wherever distances have to be measured in air, since they not only detect objects, but they can also indicate and evaluate the absolute distance between themselves and the target. Changing atmospheric conditions, (e.g. temperature variations) are compensated during evaluation of the measurement.

CONTRINEX M12 Miniature Ultrasonic Sensors Distributors


Ultrasonic devices working as diffuse or reflex sensors send out ultrasonic impulses in cyclical intervals. If these are reflected by an object, the resulting echo is received and converted into an electrical signal. Detection of the received echo is dependent on its intensity, itself dependent on the distance of the object from the sensor. The devices function according to the echo-delay principle, i.e. the time delay between the emitter and echo impulses is evaluated.

Due to the sensor's construction, the ultrasound is radiated in a lobar shape. Only reflecting objects within this sound beam are detected. Echoes in the blind zone between the sensing face and the sensing range cannot be evaluated.

The targets to be detected can be in the solid, liquid, granular or powder state. The material may be transparent or colored, of any shape, and with a polished or matt surface. All even or flat surfaces up to an angular deviation of approximately 3° from perpendicular to the sound beam can be detected with certainty, even at the maximum operating distance. Depending on surface roughness, the angular deviation may even be greater. In principle, targets can enter the sound beam from any direction.

CONTRINEX M18 Standard Small Diffuse/Reflex Ultrasonic Sensor Distributor


Contrinex ultrasonic sensors are cylindrical in form and delivered ready-to-connect with an integral 4- or 5-pole S12 connector. In addition to switching outputs, high resolution analog output (current or voltage) and dual-output (analog+digital or digital+digital) sensors are also available. Devices are offered in three technology versions: Diffuse, Reflex and Diffuse & Reflex.

With diffuse sensors, the target itself reflects the ultrasonic impulses. When the target enters a preset sensing area, the echo reflected from it causes the device to switch. To eliminate false switching, the Contrinex ultrasonic Diffuse family includes excellent background suppression in Miniature (M12) and Small (M18) devices. The latter are available in normal or short housings, including 90° sensing and teach-in versions. Sensing ranges extend from 30 to 700 mm.

In the case of reflex sensors, a fixed reflector (e.g. a small metal plate) is mounted facing the device. The switching range is set to this reflector. If an object comes between the ultrasonic sensor and the reflector, the sensor no longer recognizes the latter, which causes the output to switch. The Contrinex ultrasonic Reflex family comprises Small (M18) devices with short housings, including 90° sensing and teach-in. Use of a reflector eliminates the blind zone, so that sensing ranges extend from 0 to 700 mm.

Ultrasonic sensors can be operated in any installation position. However, positions in which materials can be deposited on the transducer surface should be avoided. In order to obtain the best reflection results, the ultrasonic sensor should be oriented in such a way that the sound waves strike the target at as close to 90° as possible. If this is not possible (e.g. with bulk materials), the maximum possible range has to be determined experimentally, and is dependent on the material, surface and orientation of the objects.

For optimum adaptation to the application conditions, devices of series 1180/1181 and 1300 - 1303 can be programmed with the PC interface device APE-0000-001. The series 1180/1181C and 1180/1181W devices are adjustable by teach-in via the device connection.

The fourth connection can be used as an external release input. Thus, ultrasonic sensors can be activated or deactivated with an external control, without switching the supply voltage on and off. An external multiplex operation can be achieved by switching the ultrasonic sensors on and off one after the other via the release input. In this case, assurance is always given that the ultrasonic sensors do not influence one another. In multiplex mode more than 10 sensors can be mounted close together without mutual interference.

SUNX Sensors

EX-F1 is a liquid level sensor with an integrated amplifier, thus there is no need to install a separate amplifier. Just attach it to a tube with two tying bands. The position can be easily changed with the release lever even after mounting, so that there is no need to cut the tying bands. Either Light-ON or Dark-ON can be selected by a switch. This is useful to check the operation during installation because it forces the output to be
