871C Miniature Inductive Sensors Allen Bradley 871C series miniature inductive proximity sensors are self-contained, solid-state devices designed to sense the presence of ferrous and non-ferrous metal objects without touching them. These small-barrel sensors are designed for space-critical applications where standard-size sensors simply will not fit. IO-Link enabled sensors offer advanced features and diagnostics including Automatic Device Configuration, multiple profiles, trending, descriptive tags, and device-specific parameters Features and Benefits IO-Link communication Three wire operation 3 conductor, 3-pin pico or 3 pin 6 in lead 3 mm, 4 mm, and 5 mm barrel diameters 10 V dc to 30 V dc Normally open contacts False pulse, transient noise, reverse polarity and short circuit protections Allen Bradley Proximity Sensor, 3mm Barrel Diameter, 5kHz Switching Frequency - 871C-DM1NP3-AP3 Looking for a sensor that includes IO-Link functionality? Choose this smooth 3mm proximity sensor from Rockwell Automation's Allen Bradley range. Its precise 0.8mm detection distance is ideal when space is limited and a standard-sized sensor won't fit. Thanks to a high switching frequency of 5kHz, the unit can quickly detect the presence of ferrous and non-ferrous metals. This device features false pulse, reverse polarity and short-circuit protection to prevent damage and ensure it's a reliable option for prolonged use. • IP67-rated, indicating it's dust-tight and waterproof, so suitable for use in contaminated conditions • Wide operating temperature range between -25°C and +70°C to suit harsh environments • Stainless steel housing is corrosion-resistant to prevent rust and signal degradation, even in damp surroundings Standards and Certifications • NEMA 1, 2, 3, 4, 12 and 13 • IEC 529 • CE Marked • cULus What are the benefits of hooking this sensor up with an IO-Link master? Connecting your device to an IO-Link master (817-1598) gives you real-time diagnostics and sensor health updates. You'll also be able to save configuration profiles that you can quickly select at start-up to increase uptime and productivity.
