Southington, Conn. — June 10, 2008.... 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.
