NON-CONTACT WEAR-FREE MAGNETIC SENSORS OFFER 360-DEGREE ANGULAR MEASUREMENT

To replace potentiometers used to measure angles and determine the location of continuously moving parts, Baumer Ltd. has introduced the MDRM/MDFM non-contact magnetic sensors. Reliable and maintenance-free, these compact sensors can measure 360 degrees of rotation without a dead band. They deliver long-term performance in dirty and high vibration operating environments and feature no bearings, wiper contacts or other moving parts that wear and break down over time. The compact MDRM/MDFM sensors feature rectangular housings with a mounting depth of just 8mm or cylindrical housings that can be installed in a variety of narrow, space restricted locations. The 8-bit sensor offers a signal resolution of 1.41 degrees suitable for applications that require course positioning, for example heavy duty equipment and vehicles. The 12-bit sensor provides a maximum resolution of 0.09 degrees for highly precise control systems such as those found in medical or rehabilitation equipment and robotic applications. The IP67-rated sensors feature current or voltage outputs that allow direct connection to standard interfaces without additional conversion. The sensors can accommodate cable or connector interfaces. MDRM/MDFM Magnetic Sensors can be incorporated into medical/rehabilitation/training, machine tool, packaging, textile production, printing, wood/timber/steel processing, energy generation, and robotic equipment and machinery, and can also be used on heavy-duty vehicles and equipment. In such applications, these sensors can determine the current position of shafts, rollers, tabletop equipment, robotic arms, pedals, lifters, grippers, containers, webs, solar panels.• angular range 360° linear • resolution 0,09 ° • response time < 4 ms • voltage supply range +Vs 4,7 ... 7,5 VDC • current consumption max. 10 mA • output signal 0 ... 4,3 VDC • type cylindrical • housing material brass nickel plated • dimension 18 mm • system accuracy ± 0,25 % • temperature drift ± 0,1 % (Full Scale) • load resistance > 1000 Ohm • output circuit voltage output • short circuit protection yes • reverse polarity protection no • working distance max. 2 mm • axial misalignment max. 0,4 mm • material (sensing face) PBTP • operating temperature -40 ... +85 °C
