  • Offer Profile
  • We offer a wide range of sensors for measuring inclination, vibration and acceleration as well as rotary encoders and inductive proximity sensors.
    We also provide systems for adjustable furniture (home automation), medical devices and caravan movers. These systems are available as standard products, but can also be fully customised. DIS Sensors has an excellent reputation in the field of customised solutions and we are proud to be your partner in innovation. Because we work with a network of carefully selected suppliers, we can also produce wide ranges at highly competitive prices.

    Beside parts, we can also offer complete solutions including the design and production of mechanical and control systems.
Product Portfolio
  • Sensors

        • Inclination sensors (QG-series)

        • The QG-series of inclination sensors measure angles in 1, 2 or 3 axes. These products are based on robust MEMS technology, in which capacitance differences can be converted into an analogue voltage within a micro-mechanical sensor chip. This analogue voltage is proportional to the angle to which the sensor is exposed. The modular design makes it easy to adapt the sensors to specific requirements.

          An inclination sensor is used in situations where accurate positioning or constant monitoring of the angle in relation to gravitational pull is essential. An inclination sensor measures the angle with respect to a horizontal position, whereby an imaginary line from the centre of the earth serves as a reference. An inclination sensor has a very wide range of applications since it can be mounted anywhere and offers flexibility in mechanical design. The sensor output has two components: a static (slope) component and a dynamic (acceleration) component. The sensor output is always a combination of these two components. The inclination sensors from DIS have a standard bandwidth of 10 Hz, although it is possible to reduce this bandwidth further at the client’s request.
        • Acceleration sensors (QG-series)

        • The QG-series of acceleration sensors measure acceleration in 1, 2 or 3 axes. These products are based on robust MEMS technology, in which capacitance differences can be converted into an analogue voltage within a micro-mechanical sensor chip. This analogue voltage is proportional to the acceleration to which the sensor is exposed. The modular design makes it easy to adapt the sensors to specific requirements. The housing is available in metal (aluminium and stainless steel), as well as in plastic.
          DIS acceleration sensors have a higher bandwidth than inclination sensors so they can measure faster movements with very high accuracy.
    • Switches

          • Tilt switches (QG-series)

          • A tilt switch is a type of switch that switches at a certain angle as compared to the horizon (similar to the old mercury switch). It is in fact an inclinometer with a switching output. Since gravity serves as a reference, just as with tilt switches, and an angle switch can be mounted anywhere, maximum mounting freedom is achieved.
            The new generation of tilt switches from DIS Sensors are based on MEMS technology and intelligent microcontroller algorithms. As a result, single or twin axis switches can be implemented with any desired switching angle. The output can be NPN or PNP. An internal buzzer is available as an option. All in a QG40 housing. Even more accurate tilt switches with higher thermal stability can be executed using the QG65 housing.
          • Inductive proximity switches (QX-series)

          • DIS manufactures the QX-series of inductive proximity switches which have a QUADRO® housing. The electronics are fully sealed in the housing, which makes these sensors ideal for use in limited spaces or under harsh conditions.

            These flat inductive proximity switches are suitable for detecting distances between 2 mm and 18 mm. A wide variety of electronic connections are available: PNP, NPN, NAMUR, NO and NC. If a standard switch from DIS Sensors does not meet your needs, we can produce custom inductive sensors (for example, adaptations to cable type and cable length, different connectors).
      • Encoders

            • Rotary encoders (QR-series)

            • The QR-series of rotary encoders enable contact-free measurement of an angular displacement from 0° to 360° without a mechanical stop. Two types of housing are available. The QR30 housing, where the sensor and magnet are mounted separately from each other, and the QR40 housing, where the magnet is integrated into the rotating shaft in the housing.

              QR30
              In the QR30 range, the sensor and magnet are mounted separately from each other, where the customer can mount the supplied magnet on its rotating axle (on-axis). The maximum distance of 3 mm between the magnet and the sensor provides sufficient space for mechanical tolerances under extreme conditions. Various outputs are available with a 10 or 12-bit resolution for a wide range of applications. While the back of the QR30 sensors is being sensitive, the QR30N sensors have got a sensitive nose.

              "Absolute" vs. "incremental"
              The QR30-series is available as absolute or incremental rotary encoders. An absolute rotary encoder contains an analog output which is linear with the angle of rotation, up to 360°. After switching on the power the sensor knows directly in which position it is located.
              An incremental encoder is specially suitable for rotational velocity of a shaft. The output of the sensor consists of pulses (A and B). The number of pulses per revolution can be between 32 and 1024. On the basis of the phase shift between the A and B signal can be determined if the shaft rotates clockwise or counterclockwise.
        • Passenger counting

        • Increasingly, it is important to record how many people enter or leave a specific area or zone. Manufacturer IRIS has the perfect solution with the IRMA (Infrared Motion Analyzer)-system. Through the application of highly sophisticated infrared technology and profiling, the system can determine how many people pass through a predefined area, as well as the direction in which they move.

          The IRMA-system tells you exactly how many customers have visited your store or your company on a certain day. Based on this information, you can also determine precisely the staffing levels necessary in your organisation at specific times on specific days.
          The IRMA-system combines two different sensor technologies. The first records the person’s thermal image, while the second senses the reflection of infrared radiation on a person’s body. This technique makes it possible to count people entering and leaving with a very high accuracy (>95%), without the need for mechanical barriers like gates. The system can also protect people from being clamped between automatic doors or check whether the same number of people leave a building at the end of a working day as entered in the morning.
            • Customized electronics

            • More and more devices use motors to perform specific functions. Obviously the correct control device plays a decisive role in the correct functioning of these motors. DIS Sensors specialises in the development of customised combinations of controllers and drivers for motors, both remote and wired. We use both infra-red (IR) and radio frequency (RF) technology. A wide variety of features for controlling motors can be programmed with software, such as memory settings, synchronisation, end positions, lock, etc.

              Together with our partners Q-tec (mechanical design and assembly) and Rotero (specialists in motion control), we can fulfill all your needs as a "one stop shop". Developing, elaborating or renewing specific designs is also no problem for us. To achieve this, DIS Sensors works with reputable partners in product design and mould production.
