Ultrasonic sensors provide a cost effective sensing method with unique properties not possessed by other sensing technologies. By using a wide variety of ultrasonic transducers and several different frequency ranges, an ultrasonic sensor can be designed to solve many application problems that are cost prohibitive or simply cannot be solved by other sensors. Ultrasonic sensors continuously emit high frequency sound pulses inaudible to the human ear  which travel away from the sensor, hit the surface of the target and are reflected back to the sensor. The sensor electronics measure the time taken by the signals to return after being reflected by the target surface.

Since the speed of sound is affected by air temperature, our ultrasonic sensors include a built-in temperature sensor. Level/distance measurements are automatically temperature compensated throughout the operating temperature range of the sensor.

Classic applications include proximity sensing, object presence or absence, obstacle detection for automated vehicles, distance measuring, level measuring, etc etc


  • Direct measuring value output in mm/cm or % via LED display
  • Temperature compensation  for accurate measuring with fluctuating temperature
  • accuracy with temperature drift internal compensation, ±  1%
  • Numerical sensor setting via LED display  for a complete pre-setting of the sensor
  • 1 or 2 pnp or npn switching outputs for all controls
  • Analogue output 4-20 mA and 0-10 V  for two signals in one device (optional), reverse polarity protection
  • Operating voltage 9-30 V for application in various supply networks
  • Additional teach-in-function for a traditional setting of detect points
  • Automatic synchronisation for simultaneous operation of up to ten sensors in confined spaces
  • Automatic switchover between current and voltage output  for simple operation
  • Housing material brass sleeve, nickel-plated, plastic parts, PBT, TPU (stainless steel optional)
  • protection rating IP67
  • vibration & shock complies to IEC 60068-2-27

Different operating modes and device configurations enable our ultrasonic sensing systems to be used in most conceivable automation applications

The HPS range: pressure & chemicals resistant

The ultrasonic sensor that is employed for aggressive media filling level control applications in positive pressures of up to 6bar. The sensor's special software filters even facilitate its use in tanks which are filled from the top or are equipped with an agitator. It features a 1/2'' threaded spud and can be directly installed in pressure tanks. The sensor accommodates an analogue output 4-20mA and 0-10V as well as a pnp switched output. Its housing is made of stainless steel. As of a positive pressure of 1bar, the sensor can be employed for filling level control applications up to 1m. All sensor settings are directly made at the sensor via TouchControl, consisting of a three-digit digital display and two pushbuttons. During operation, the measured distance is directly indicated on the digital display in mm/cm or per cent.

and when size does matter

think of nano - the smallest of its kind

nano – what's in a name? At just 55 mm long, including plug, the nano is the shortest M12 ultrasonic sensor on the market. The housing's design and mounting is compatible with many inductive and capacitive sensors. This facilitates the conversion to ultrasonic sensors for critical applications.

The new pico+ ultrasonic sensors with IO-Link


  • Even more compact: only 41 mm long, with optional angular head
  • Even more up-to-date: with IO-Link interface
  • Even more economical:
  • thanks to new production methods and M18 metal housing

The three pico+ operating types:

  • Simple detect point
  • Two-way reflective barrier
  • Window mode

Teach-in for a simple detect point

  • Position object to be detected (1) at the required distance
  • Place Pin 5 at +UB for three seconds
  • Then place Pin 5 again at +UB for 1 second

Teach-in for a two-way reflective barrier with a firmly fitted reflector

  • Place Pin 5 at +UB for three seconds
  • Then place Pin 5 again at +UB for 10 seconds

For a window adjustment

  • Position objects on the window limit near to the sensor (1)
  • Place Pin 5 at +UB for three seconds
  • Then move the object onto the window limit away from the sensor (2)
  • Then place Pin 5 again at +UB for 1 second

Receptive to the new IO-Link!

The new IO-Link interface in the pico+  sensors provides us with the requirements to effect continuous communication through all system architecture levels up and into the sensor itself. In this way, both machinery and equipment can be run in a more productive manner. IO-Link can enormously simplify the startup and maintenance of either a machine or appliance.

Easy to synchronise

A number of pico+sensors can be run closely packed in applications synchronised to stop them influencing one another. To this end, all the sensors are to be electrically connected one to another with Pin 5.

In instances of where a number of sensors are run at an IO-Link master, then the master's function is to assume synchronisation (Pin 5 must not wired under IO-Link operations).

Detects what has to be detected: using 3 ranges.

  • Example 1: To measure the level of a shampoo bottle through the screw cap opening, the need is for a short measuring distance and a narrow sound field.
  • Example 2: On the other hand, the need in measuring the filling level of potatoes is for a sensor with a broad sound field and a high degree of sensitiveness – all the more so since the potatoes can absorb and diffusely reflect the beam.
  • Example 3: A sensor with a maximum 1.3 m detection range is available for considerable measuring distances.
