The Allen-Bradley Bulletin 871FM metal, flat-pack, inductive proximity sensors from Rockwell Automation are sensors built for harsh environments.

Enabled with IO-Link technology, the Bulletin 871FM sensors deliver more comprehensive diagnostic and parameter data to the controller over EtherNet/IP from the IO-Link master module.

The fully shielded, Bulletin 871FM sensors’ 8 mm (20x32x8 mm) and 14 mm (30x52x14 mm) stainless-steel rectangular housings can be installed in space-critical applications. The stainless-steel construction of these new proximity sensors is optimal for sensing small parts in 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, making them suitable for extreme environments, particularly in automotive welding applications. They are also suited for food and beverage processing plants, stamping, material handling and a wide variety of other sensing applications.

Additionally, the Bulletin 871FM metal, flat-pack sensors feature  visible, bicolor, status light-emitting diodes (LEDs), margin indication for setup and 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.
