Pepperl+Fuchs NBB2-12GM40-Z0 88190 2 mm flush 2-wire DC Inductive
Proximity Sensor
1. Overview of the Pepperl+Fuchs NBB2-12GM40-Z0 88190
The Pepperl+Fuchs NBB2-12GM40-Z0 88190 is an M12 cylindrical
inductive proximity switch with a threaded stainless steel housing.
Measuring only 43 mm in length, it delivers stable, contactless
detection of metal targets within a distance of 2 mm. It supports a
wide range of 5…60 V DC power supplies, a two-wire normally open
output, and a high switching frequency of 0…1000 Hz, enabling
high-speed counting and position feedback. IP67 protection, reverse
polarity protection, and short-circuit protection ensure long-term
reliable operation in machine tools, assembly lines, or logistics
equipment.
Thanks to Pepperl+Fuchs' industrial-grade design, the sensor can be
directly connected to the digital inputs of PLCs, relays, or
frequency converters without an additional amplifier, significantly
simplifying system integration. LED status indicators facilitate
quick on-site diagnostics, while UL/cULus certification and a
2250-year mean-to-failure time-to-failure (MTTF) data provide
equipment manufacturers and end users with quantifiable safety and
longevity assurance. Whether it's precision positioning in a
placement machine or bottle cap inspection on a packaging line, the
NBB2-12GM40-Z0 can improve the efficiency and yield of automated
production lines with millimeter-level repeatability.
2. Core Features:
1. Core Detection Performance
• Rated sensing distance: 2 mm (flush mount), effective operating
window 1.8 – 2.2 mm
• Switching function: Normally open (NO), two-wire DC output,
eliminating the need for a separate power cable and simplifying
wiring
• Switching frequency: 0 – 1000 Hz, enabling stable detection of
metal targets even in high-speed motion
• Hysteresis: Typical 5%, ensuring reliable differentiation between
actuation and reset points and preventing chatter
2. Electrical and Mechanical Parameters
• Power supply range: 5 – 60 V DC, an extremely wide voltage
window, compatible with PLC, relay, and inverter inputs
• Load capacity: 2 – 100 mA, off-state current ≤ 0.5 mA, voltage
drop ≤ 5 V
• Protection: Reverse polarity protection (reverse connection
permitted), pulse short-circuit protection, and self-recovery after
faults
• Housing material: Nickel-plated brass, PBT sensing face; IP67
rating, -25 – +70°C stable operation
• Connection method: 2 m gray PVC cable, 3 mm Outer diameter, bend
radius > 30 mm
• Status Indicator: 360° visible yellow LED, real-time display of
on/off status
3. Reliability and Certifications
• Service Life: MTTFd = 2250 years (EN ISO 13849), Mission Time TM
= 20 years
• International Certifications: cULus Listed, CCC Compulsory
Certification, compliant with EN IEC 60947-5-2
• Application Environment: Suitable for machine tools, assembly
lines, logistics conveying, packaging equipment, and other
applications requiring non-contact, high-speed, and high-precision
metal detection.
