Short-length inductive proximity sensors allow detection in tight spaces

July 5, 2017 By Lisa Eitel Leave a Comment

When working with applications in spindles, grippers, and robotics, space is typically very tight. Unfortunately, that fact doesn’t eliminate the need for automation. If anything, it increases it. These ever-shrinking spaces can create enormous stresses on standard proximity sensors. As a result, manufacturers and users of automated machinery are always requesting greater miniaturization and higher stress tolerances from sensor suppliers.

IFRM 03 Short series proximity sensors

In response to these needs, Baumer has created the new IFRM 03 Short, an addition to the 3-mm inductive proximity sensor family.

These 3-mm diameter sensors are available with either 16 or 12-mm length. Plus they offer a minimum operating voltage of 6 Vdc, a significant decrease from the typical 10 Vdc. Baumer is known for its sensor performance. But the brand also stands out via its consistency from sensor to sensor. In a quality test of ten randomly-drawn sensors from production, the variation in sensing distance over the operating temperature range was only ±10% and consistent across the ten samples. This is in contrast to a test of comparable models whose variation was up to ±30% over the same temperature range and varied considerably from sensor to sensor. The result here is less calibration, error, and variation in performance at different sensor points if the Baumer sensors are used.

Handling tight spaces with alternative cable runs

The shorter housing option (12-mm) includes a litz wire connection. This was done to allow for a much tighter bend radius of only 5 mm, allowing the sensors to fit into a much shallower install space.

More detail on the litz wire concept is available via New England Wire Technologies at newenglandwire.com.

Further information on the Baumer miniature inductive family is available at: baumer.com … and detailed specifications on the IFRM Short family are at bit.ly/2tO0BZS.
