(EN) Redundant, non-contact angle and distance measurement for mobile machines!

  • In the field of mobile commercial vehicles, safety requirements are increasing, especially within the EU. This presents not only suppliers, but also manufacturers of vehicles, with new challenges. In order to make it as easy as possible for manufacturers to adapt to new requirements, the Buchenbach based firm SIKO GmbH has developed the MSK320R bearing-free rotary encoder. Designed especially for use in forklift trucks, it helps users to implement safety requirements such as EN 1175 (safety of industrial trucks). For example, in AGVs (driverless transport systems), the compact magnetic sensor can be used directly on the wheels for speed or rotation detection.

     SIKO non-contact angle and distance measurement

    From two comes one

    To meet functional safety requirements, many manufacturers rely on redundant signals. This can be achieved either by attaching two sensor heads or a redundant sensor. The MSK320R is equipped with two magnetic sensors for redundant position measurement. It thus has two completely separate position channels (A1, A2, /A1, /A2, B1, B2, /B1, /B2), and can be used in combination with a secure input card in the overall system up to performance level PLd.

    Space saving and cost optimized

    Despite the higher component density, the housing of the MSK320R remains very small and compact at 35 x 25 x 10 mm.

    The advantage of the MSK320R lies in cost and space savings when compared to the use of two separate magnetic sensors with simple channels. There is also no need for the additional wiring and mounting required for two sensors.

    Linear or rotary:

    By selecting the appropriate scale, the sensor can be used for linear displacement measurement (in combination with the MB320/1 magnetic tape) or for angle and speed detection (in combination with different SIKO rings - for example, the MRI01, MR320, or MBR320 rings can all be used).

    Functional even in extreme conditions:

    With an IP67 safety rating and a wide operating temperature range from -40 to 85°C (-40 to 185 °F) the MSK320R can also be deployed in extreme conditions. Negative temperatures and condensation in outdoor use, and even extreme solar radiation, are no problem for the sensor.

    Like all of the magnetic sensors manufactured by SIKO, the MSK320R is also resistant to dust, chips, oils, grease, and moisture.

    The MSK320R in continuous operation:

    The open, contact-free measuring system is extremely wear-resistant and low-maintenance, and the MSK320R is predestined for long-term use in the field of mobile automation. 

    MSK320R profile:

    • Increased safety provided by independent output channels
    • Two magnetic sensors and two signal conditioners in one housing
    • SIKO ZM-housing (small, compact, and space saving)
    • Accuracy: to 2 mm
    • Repeatability: +/- 1 increment (linear +/- 0.0125 mm)
    • Ambient temperature: -40 to +85°C
    • Also available with German plug
    • Cut costs by mounting an MSK320R sensor instead of two standard MSK320 sensors
