Company and Product News

Rockwell Automation introduced its Allen-Bradley Bulletin 871FM miniature, metal, flat-pack, inductive proximity sensors. This new line of smart proximity sensors are designed to be rugged and built for harsh environments, helping industrial automation customers to potentially improve the data gathered from their machines.

These Bulletin 871FM sensors are enabled with IO-Link technology to help deliver more comprehensive diagnostic and parameter data to the controller over EtherNet/IP from the IO-Link master module. This capability can help to minimize downtime and increase productivity.

Different than traditional, tubular proximity sensors, these shielded, Bulletin 871FM sensors’ 8 mm (20x32x8 mm) and 14 mm (30x52x14 mm) stainless-steel rectangular housings can be installed in low-profile, space-limited applications. The more compact design and all stainless-steel construction of these new proximity sensors helps to enable sensing small parts in more demanding environments.

Bulletin 871FM sensors are also available in welding models with sensing ranges up to 10 mm and Factor-1 equal sensing for different ferrous and nonferrous metals. Weld-immune models are equipped with an Allen-Bradley ToughCoat Finish coating to help prevent weld-slag buildup, helping these sensors to work in more extreme environments, particularly in automotive welding applications. These sensors are also suited for multiple applications, such as food and beverage processing plants, stamping, and material handling applications.

Additionally, the Bulletin 871FM metal, flat-pack sensors feature visible, bicolor, status light-emitting diodes (LEDs), margin indication to help with setup, auto detect NPN/PNP, and complementary N.O. and N.C. outputs. The sensors are available with either 2 m cable or 0.2 m pigtail cable, with integral M12 Micro Quick Disconnect connectivity.
