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:
