Inductive Proximity Sensors

Description
Bulletin871C inductive proximitysensors are self-contained, general
purpose, solid-state devices designedto sense the presence of ferrous andnon-ferrous metal objects withouttouching them.
The switch body consists of a plasticface and either a nickel-plated brassbarrel or plastic barrel. The electroniccircuitry is potted for protection againstshock, vibration, and contamination.
These sensors are available in 3, 4, 5,6.5, 8, 12, 18 and 30mm diameters,with smooth or threaded barrels.Connection options include a 2m cable,micro quick-disconnect, and picoquick-disconnect.
Features

Description
Bulletin871C inductive proximitysensors are self-contained, solid statedevices designed for most industrialapplications where it is required tosense the presence of metal objectswithout touching them. These specialextended temperature models are idealfor industrial environments wheretemperatures can reach as high as212F (100C) or as low as 40F(40C). They are available for currentsource (PNP) operation with a normallyopen output.
Each switch has a plastic face and anickel-plated brass housing which meetNEMA 1, 2, 3, 4, 12, 13 and IP67 (IEC529) enclosure standards. Theelectronic circuitry is potted forprotection against shock, vibration, andcontamination.
These sensors are available in 12, 18,and 30mm diameters. Connectionoptions include: 2m (6.5ft) PUR cable ormicro quick-disconnect (4 pin,1 keyway).
