Allen-Bradley Bulletin 871FM miniature, metal, flat-pack, inductive proximity sensors

The Allen-Bradley Bulletin 871FM miniature, metal, flat-pack, inductive proximity sensors from Rockwell Automation are rugged, smart sensors built for harsh environments. Enabled with IO-Link technology, the sensors deliver comprehensive diagnostic and parameter data to the controller over EtherNet/IP from the IO-Link master module.

Unlike traditional, tubular proximity sensors, the fully shielded Bulletin 871FM sensors’ 8 mm and 14 mm stainless steel rectangular housings can be installed in low-profile, space-critical applications. The compact design and all stainless steel construction of the proximity sensors is intended for sensing small parts in demanding environments.



The 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 build-up, making them suitable for environments such as automotive welding applications. They are also suitable for food and beverage processing plants, stamping, material handling and a wide variety of other sensing applications.

The metal, flat-pack sensors feature highly visible, bicolour status LEDs, margin indication for optimal set-up and auto detect NPN/PNP, and complementary NO and NC outputs. The sensors are available with either a 2 m cable or 0.2 m pigtail cable, with integral M12 Micro Quick Disconnect connectivity.
