Micropulse Sensors With Profibus-DP Interface

These magnetostrictive linear position sensors are now available with a Profibus-DP. This interface is one of the most widely used fieldbus standards for networking peripheral equipment in general automation applications, such as press feeds, cut-offs, machine tools, packaging machinery, assembly, plastics machinery and similar applications.

With a stroke length of up to 4 m (157 in.), the profile-style units provide sub-millisecond position updates, position resolution of 5 microns (0.0002 in.), and velocity resolution of 0.1mm/sec (0.004 in./sec). Automatic baud rate detection ensures trouble-free start up in Profibus systems with speeds of 9.6 kbps and 12 Mbps.

The new units are CE-approved, shock-rated to 100g/6ms and sealed to IP67 requirements – immune to contamination from dust, chips, dirt and oil, as well as outdoor environments. Non-contact, wear-free design ensures peak accuracy over the entire life of the unit, while absolute position sensing eliminates the need to re-home after a power outage.

These sensors operate on 24VDC, protected against reverse polarity, with ±15VDC operation available as an option. All standard analog and digital outputs are available in the product family.
