Highlights

  • Very small housing dimensions with two M3 threaded sleeves
  • Installation-compatible with many optical sensors a true alternative for critical applications
  • Improved temperature compensation adjustment to working conditions within 45 seconds

Basics

  • 1 switching output in pnp or npn variant
  • Analogue output 4-20 mA or 0-10 V
  • microsonic Teach-in using a button
  • 0.1 mm resolution
  • 20–30 V operating voltage

Description

The sks sensors

are the smallest cuboidal ultrasonic sensors from microsonic and feature a housing design reduced by 33% compared to the zws sensors.

The miniature housing of the sks ultrasonic sensor fits in constricted installation locations e.g. for sampling conductor boards and wafer in the electronics industry, for presence checks on conveyor bands or fill-level measurement in small containers. When capacitive or optical sensors come up against their physical limits, installation compatibility of ultrasonic sensors with many optical sensors enable their deployment: simply secured with two M3 screw sockets.

For the sks sensor range

two output versions are available:

1 switching output, optionally in pnp or npn circuitry
1 analogue output 4–20 mA or 0–10 V

The temperature compensation

of the analogue sensors profits from a significant improvement. The sensors reach their operating point only 45 seconds after activation of the operating voltage. We now compensate for the influence of self-heating and installation conditions. This brings improved precision shortly after activation of the supply voltage and in running operation.

The Teach-in button

on the top of the sensor allows for the convenient configuration of the desired switching distance and operating mode.

Two LEDs

show the operating state of the sensor.

The sks sensor with switching output has three operating modes:

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

permit configuration using the usual microsonic Teach-in procedure.

The switched output is set by:

positioning the object to be detected within the desired distance (1) to the sensor, pressing the button for approx. 3 seconds and then pressing it once more for approx. 1 second. Ready.

A two-way reflective barrier

can be set up with the help of a permanently mounted reflector by mounting the sks sensor and the reflector. Then press the button for approx. 3 seconds and then pressing it once more for approx. 10 seconds. Now, the two-way reflective barrier has been set.

Set a window

by initially positioning the object to be detected on the sensor-close window limit (1), pressing the button for approx. 3 seconds, shifting the object to the sensor-distant window limit and pressing the button once more for approx. 1 second. Ready.

Set the analogue output

by initally positioning the object to the detected on the sensor-close window limit (1), pressing the button for approx. 3 seconds, shifting the object to the sensor-distant window limit and pressing the button once more for approx. 1 second. Ready.

and rising/ falling analogue characteristic curve can also be set using the button.
