Pepperl+Fuchs NBN4-12GM40-Z0 Sensor | Cylindrical, M4, 1.2mm, DC 3-Wire, PNP, Short Cable

Pepperl+Fuchs NBN4-12GM40-Z0 specifications. Ultra-miniature inductive sensor, M4, 1.2mm, DC 3-wire PNP, 0.4m cable, for small parts.

Product Overview

The Pepperl+Fuchs NBN4-12GM40-Z0 is an ultra-miniature inductive proximity sensor designed for detecting tiny metallic objects in extremely confined spaces. It features an M4 x 0.5 threaded barrel with a 1.2mm sensing distance. The sensor operates on a DC 3-wire system with a PNP (sourcing) output and a normally open (NO) function. Its extremely compact size, short 0.4-meter cable, and short body length make it ideal for integration into small machinery, micro-assembly systems, and robotics where space is critical.
