Industrial Ultrasonic Proximity Switch , Ultrasonic Distance Sensor High Precision

Description

Brife introduction of ultrasonic sensor

Ultrasonic sensors present the ideal solution for non-contact position and distance measurement in all industrial areas where environmental conditions such as dust, smoke or steam may affect the sensors. Objects consisting of a variety of materials can be detected to within millimeters regardless of color or shape.

Ultrasonic sensors have proven their reliability and precision in many industries and applications, including:

• lumber and furniture
• construction materials and equipment
• farming equipment
• level control applications

Technical data

External synchronization

The sensor can be synchronised by the external application of a square wave voltage. A synchronisation pulse at the
synchronisation
input starts a measuring cycle. The pulse must have a duration greater than 100 μs. The measuring cycle starts with
the falling edge of a synchronisation pulse. A low level > 1 s or an open synchronisation input will result in the normal
operation
of the sensor. A high level at the synchronisation input disables the sensor. Two operating modes are available:
1. Multiple sensors can be controlled by the same synchronisation signal. The sensors are synchronised.
2. The synchronisation pulses are sent cyclically to individual sensors. The sensors operate in multiplex mode.

Internal synchronization

The synchronisation connections of up to 5 sensors capable of internal synchronisation are connected to one another. When
power is applied, these sensors will operate in multiplex mode.
The response delay increases according to the number of sensors to be synchronised. Synchronisation cannot be performed
during TEACH-IN and vice versa. The sensors must be operated in an unsynchronised manner to teach the evaluation limits.
