Pepperl+Fuchs NBN40-U1-Z2 inductive proximity sensor

Pepperl+Fuchs NBN40-U1-Z2 is an inductive proximity sensor, a standard model in its industrial automation sensor product line. The following are the key features and classification basis of this model:

Product type and technical principle

This sensor uses inductive technology to detect the proximity of metal targets through electromagnetic fields, and is suitable for non-contact position detection in industrial automation.

Specific classification is "Inductive Proximity Sensor", which is commonly used in mechanical manufacturing, logistics systems and other scenarios.

Core parameters

Detection range: 0–40 mm, rated working distance is 40 mm, actual working distance range is 36–44 mm.

Output configuration: supports normally open/normally closed (NO/NC) dual mode, adopts two-wire (2-wire) output design.

Electrical characteristics: The operating voltage range is 5–60 V DC, supports reverse polarity protection and short-circuit protection, and the maximum switching frequency is 100 Hz.

Structure and protection

Housing material: Combination of metal (nickel-plated brass or epoxy powder coating) and polyamide (PA), with both mechanical strength and corrosion resistance.

Protection level: up to IP68/IP69K, suitable for harsh environments (such as dust, high-pressure water washing, etc.).

Installation method: Supports non-flush installation (non-embedded) for flexible deployment.

Additional functions and certifications

Built-in dual yellow LED indicator, visible 360°, provides switch status feedback.

Complies with international certifications such as CE, cULus, CCC, and passed EN IEC 60947-5-2 standard.

Some models support IO-Link communication, which is easy to integrate into the Industry 4.0 system to realize remote parameter configuration and fault diagnosis.

Application scenarios

Typical uses include robot arm positioning, conveyor belt object detection, automated assembly lines, etc., especially suitable for industrial environments that require high protection level and stability
