DETAILED DESCRIPTION

Carlo Gavazzi UA12/18/30 Ultrasonic IO-Link sensors

This ultrasonic IO-Link sensor series of UA12, UA18 and UA30 provides superior sensing solutions with a good price-performance-ratio for a variety of industry applications. The ultrasonic sensors are excellent at contactless position and distance measurement and they are able to detect any target regardless of its colour, transparency or surface.

Because of their resistance to high and low temperatures and immunity against dust, steam and fumes, these Ultrasonic sensors are especially well suited to harsh environments.

The UA12, UA18 and UA30 come in a purely digital version and a combined version with one digital and one analog output.

Sensing distances go from 20 to 6000 mm and only plug versions are available.

Due to improved technology, an extended sensing distance and a reduced housing length, these sensors make for a state of the art sensor family with high accuracy, versatility and resilience!

Advantages of the new IO-LINK ultrasonic sensor series

-Extremely short design with high performance capacityand for applications with low space conditions

-Stable processes with very high resolution, reproducibility and low linearity error

-High stability thanks to low temperature drift, evenin an expanded temperature range up to 70°C

-Versatile usage thanks to the integration of 4 functions in a single sensor: Single point-, Window-, Two-point mode and Reflex operation

-Sensor-independent multiplex-operation to prevent sensors from influencing each other detecting odd objects (analog)

-Sensor-independent synchronization mode, for example, for thickness measurements or monitoring large areas (analog)

-IO-Link for easy commissioning and diagnostics

Multiplex mode (Analogue versions only)

In multiplex mode the sensors pulse sequentially (only one sensor is active at a time). This prevents mutual interference and allows the sensors to be mounted facing each other. In multiplex mode each sensor must complete the cycle of pulse and reception before the next sensor pulses. This setup eliminates the risk of interference from other sensors however the response time is slower.

Up to 10 identical sensors can be used for this function. It is configured via IO-Link, and requires each sensor to be assigned a role as either master or slave as well as being assigned a number in the network. The master sensor must have the highest number, and is the last to pulse if in multiplex mode.

Synchronization mode (Analogue versions only)

In synchronous mode the sensors pulse simultaneously. This is useful when monitoring a larger area, or when several sensors are placed closely together to monitor the same surface. Synchronous mode has a faster response time than multiplex mode
