sks ultrasonic proximity switch

Product catalog summary
Overview: The SKS ultrasonic sensors by microsonic GmbH are compact, cuboidal sensors designed for critical applications where space is limited. They offer installation compatibility with many optical sensors and are equipped with advanced features such as IO-Link interface and Smart Sensor Profiles.
Key Features:
  • Very small housing dimensions with two M3 threaded sleeves.
  • IO-Link interface for enhanced device communication.
  • Smart Sensor Profiles for better transparency between devices.
  • Optional SoundPipe sks1 for focused sound field measurements.
  • Improved temperature compensation, reaching operating conditions within 45 seconds.
  • UL Listed for Canadian and US safety standards.
  • Available in pnp or npn switching output variants, with analogue output options of 4-20 mA or 0-10 V.
  • Microsonic Teach-in feature for easy configuration.
  • High resolution of 0.1 mm and operating voltage range of 20–30 V.
Applications: The SKS sensors are suitable for use in tight spaces such as electronics industry for sampling conductor boards, presence checks on conveyor bands, and fill-level measurement in small containers.
Output Versions:
  • Push-Pull switching output with IO-Link interface.
  • Switching output in pnp or npn circuitry.
  • Analogue output of 4–20 mA or 0–10 V.
Technical Specifications:
  • Operating voltage: 15-30 V DC, reverse polarity protected.
  • Voltage ripple: ± 10%.
  • No-load current consumption: ≤ 25 mA.
  • Connection type: 4-pin M8 initiator plug.
  • Protection class: IP 67.
  • Operating temperature: -25°C to +70°C.
  • Storage temperature: -40°C to +85°C.
  • Weight: 8 g.
Accessories: Compatible accessories include KST4A-2/M8, KST4A-5/M8, KST4G-2/M8, KST4G-5/M8, and SoundPipe sks1.

The sks sensor is the smallest cuboidal ultrasonic sensor from microsonic and features 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...

sks ultrasonic proximity switch-4

For the sks sensor family three output versions are available: 1 Push-Pull switching output with IO- 1 switching output, optionally in pnp- Link interface 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...

Teach-in of a switching point Teach-in of a two-way reflective barrier 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 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...

NCC/NOC and rising/ falling analogue characteristic curve can also be set using the button. SoundPipe sks1 intensively bundles the sound field and allows measurements in openings with small diameters. The SoundPipe sks1 (accessory) is pushed on the transducer of the sks. IO-Link integrated in version 1.1 for sensors with Push-Pull output. The sks-15/CF/A supports the Smart Sensor Profile. You have special requirements? Nothing as simple as that. With us, you can easily find an individual solution. Let us talk about your application: +49 231 97 51 51-82.
