Pepperl+Fuchs Inductive Sensor NBB3-V3-Z5, 3 mm Sensing Range, NAMUR Output, Non-flush, Cable 2 m 301162

In industrial automation, detecting metal objects reliably in hazardous areas demands a sensor that meets strict safety standards without compromising performance. The Pepperl+Fuchs NBB3-V3-Z5 inductive sensor solves this by providing a NAMUR output signal compatible with intrinsically safe circuits, allowing direct connection to safety barriers in explosive atmospheres.

Who is it for

This sensor is for automation engineers and maintenance teams in chemical, petrochemical, and pharmaceutical plants who need non-contact metal detection in Zone 0, 1, or 2 hazardous areas. It suits applications requiring a compact rectangular housing with a 3 mm sensing range and a 2-wire connection for simple wiring.

Main features

• 3 mm sensing range for reliable detection of ferrous and non-ferrous metals
• Non-flush installation allows the sensing face to protrude, maximizing detection distance
• 2-wire NAMUR output (normally open) for intrinsic safety with approved barriers
• Operating voltage 8.2 V DC via safety barrier, current consumption ≤1 mA when target detected, ≥3 mA when not detected
• Switching frequency up to 2000 Hz for fast response in high-speed applications
• PBT housing and sensing face resist chemicals and mechanical wear
• IP67 protection against dust and temporary immersion
• 2 m PVC cable for flexible installation
• Operating temperature range -25 to 100 °C for harsh environments

Tips

When installing, ensure the sensor is connected to a certified intrinsically safe barrier that limits voltage and current to safe levels. For non-flush mounting, allow sufficient clearance around the sensing face to avoid false triggering from nearby metal. Use the 2 m cable to route away from high-voltage lines to minimize electrical noise.
