The pico+ ultrasonic sensors

are a compact series with M18 threaded sleeves and a housing length of only 41 mm. In addition to the variants with an axial beam direction, there is also a housing variant with a 90° angled head and radial beam direction.

With four detection ranges from 20 mm to 1.3 m and three different output stages, this sensor family covers a wide range of applications.

Sensors with the Push-Pull output stage support SIO and IO link modes. Sensors with analogue output are optionally available with 4–20 mA current output or 0–10 V voltage output.

In SIO mode, sensors are configured using the microsonic Teach-in procedure on pin 5.

The sensors are Listed to applicable UL Standards and requirements by UL for Canada and the US.

For the pico+ sensor family

there are 2 output stages and 4 detection ranges available:

1 Push-Pull switching output with pnp or npn switching technology
1 analogue output 4–20 mA or 0–10 V

Sensors with switching output have three operating modes:

  • Single switching point
  • Two-way reflective barrier
  • Window mode

Teach-in of a single switching point

  • Place object to be detected (1) at the desired distance
  • Apply +UB to pin 5 for about 3 seconds
  • Then apply +UB to pin 5 again for about 1 seconds

Teach-in of a two-way reflective barrier

with a fixed reflector

  • Apply +UB to pin 5 for about 3 seconds
  • Then apply +UB to pin 5 again for about 10 seconds

Teach-in of a two-way reflective barrier

For configuration of a window

  • Place object at the near edge of the window (1)
  • Apply +UB to pin 5 for about 3 seconds
  • Then move the object to the far edge of the window (2)
  • Then apply +UB to pin 5 again for about 1 seconds

and rising/falling analogue characteristic curve can also be set via pin 5.

optionally permits the extensive parameterisation of pico+ sensors. The LCA-2 LinkControl adapter , which is available as an accessory, can be used to connect pico+ sensors to the PC.

Easy to synchronise

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

Synchronisation using pin 5

If more than 10 sensors must be synchronised, this can be carried out with the SyncBox1 , which is available as an accessory.

In instances of where a number of sensors are run at an IO-Link master, then the master's function is to assume synchronisation.

Updated to IO-Link version 1.1

The pico+ sensors with the extension „/A” in the order name are updated to IO-Link version 1.1 and support the Smart Sensor Profile. Please note that these sensor with the updated IO-Link version do not support IO-Link version 1.0 any longer. For example, when replacing pico+15/F with a pico+15/F/A you have to integrate the new device ID in the IO-Link master. In SIO mode, the sensors are compatible with each other. The predecessor models pico+xxx/F can be found in the sensor archive.
