Product Details
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

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, 2m Cable, 3kHz Switching Frequency - 871C-MM1NP3-E2
Use this proximity sensor from Rockwell Automation's Allen Bradley range to detect ferrous and non-ferrous metals reliably. With a small 3mm barrel and a 1mm sensing distance, you can use it in tight spaces where a regular sensor wouldn't fit. The component benefits from false pulse, short-circuit and reverse polarity protection, to prevent electrical surges and other common issues that could damage it. This model features an IO-Link communication protocol that connects to the Connected Enterprise through a master tool (817-1598) for faster installation and setup.
Shielded design prevents electric noise from interfering with the signal
Flexible 2m PVC cable to access hard-to-reach areas
Broad operating temperature range between -25°C and +70°C for use in harsh conditions
Stainless steel housing is resistant to rust and oxidation for prolonged use, even in humid environments
Fast 3kHz switching frequency lets you take measurements quickly
