Draw-wire sensors now offer larger measuring ranges and CANopen interface 

Draw-wire displacement sensors from Micro-Epsilon are used successfully in many different industries, one of the most important being mobile machinery, where the sensors need to be compact, provide large measuring ranges (typically 6m to 8m) and offer an attractive price/performance ratio. 

A common application for draw-wire sensors in mobile machinery is the measurement of boom and support positions. Telescopic loaders, for example, often require a measuring range of 8m. In addition to analogue outputs, the demand for digital interfaces is also increasing, particularly for CANopen. 

To better serve these applications, Micro-Epsilon has expanded its wireSENSOR WPS-MK88 and wireSENSOR WPS-K100 series of draw-wire sensors with larger measuring ranges and CANopen interface. 

The wireSENSOR K100 series of draw-wire displacement sensors measure distance and position precisely, combining high performance for outdoor use with an excellent price/performance ratio. The series now offers a larger measuring range of up to 8 m, as well as a CANopen interface for all measuring ranges up to 8 m, making the sensors ideal for off-highway vehicles, mobile machinery, mobile cranes and lifting technology. The compact K100 series is protected by a glass fibre-reinforced plastic housing, as well as separate drum and spring spaces, making the sensors extremely robust (IP69K) against external influences.  

The MK88 series of draw-wire sensors has also been expanded with a larger measuring range of up to 6 m, as well as a CANopen interface for all measuring ranges up to 6 m. The MK88 is specially designed for mobile applications in series such as mobile cranes and mobile working platforms. The combination of compact size, robustness and price makes the sensors unique, offering new potential in design and cost optimisation. 

Ever-expanding portfolio 

Draw-wire displacement sensors from Micro-Epsilon are extremely robust and flexible. They measure positions and distances between 50mm and 50m. Robust housings protect against external influences. Due to their compact design, the sensors can also be integrated in narrow installation spaces. Measurements are performed in a simple way, quickly and with a long sensor service life. Output of measurement values is either analogue or digital, depending on the sensor model. For customer applications, various adaptations can also be implemented at any time. For example, the measuring wire can be guided over deflection pulleys to achieve an ideal measuring situation. Micro-Epsilon’s portfolio of draw-wire displacement sensors includes more than 120 models in different designs and measuring ranges.
