Allen Bradley Inductive Smooth Barrel Proximity Sensor, 1 mm Detection, PNP NO, 10 → 30 V dc | 871C-MM1NP3-E2

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

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

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

• CE Marked
• cULus
• IEC 529
• NEMA 1, 2, 3, 4, 12 and 13

This device features several NEMA ratings and is IP67-rated, meaning it’s dustproof, waterproof and suitable for indoor and outdoor industrial setups.
