Pepperl+Fuchs NBB2-8GM30-E2 | M8 Inductive Sensor, 2mm Flush, PNP NO, 2m Cable
Pepperl+Fuchs NBB2-8GM30-E2 inductive proximity switch. M8×1 brass housing, 2mm flush range, PNP NO, 10-30V DC, 2m fixed PVC cable, IP67, -25 to +70°C.
Product Overview
The Pepperl+Fuchs NBB2-8GM30-E2 is a flush-mountable inductive proximity sensor from the NBB (Narrow Body Barrel) M8 series, designed for non-contact detection of ferrous metal targets in space-constrained machine areas. It features an M8×1 nickel-plated brass threaded housing, 2 mm nominal sensing range (Sn) when flush-mounted, PNP Normally Open (NO) output, and a 2 m fixed PVC cable. Powered by 10–30 V DC, it is widely used for cylinder position feedback, part-presence verification, and index sensing on compact automation equipment.

Key Features
-
Flush Mount in Metal: 2 mm range maintained even when installed flush in a metal bracket (∅8.2 mm hole) — no reduction factor, simplifying cutout design.
-
High Switching Frequency: 3 kHz allows detection of fast-moving parts on high-speed conveyors or rotary indexing tables.
-
Fixed 2m Cable: Pre-wired with oil-resistant PVC cable — no separate M8 connector needed; suitable for direct home-run to terminal block or junction box.
-
Rugged Brass Housing: Nickel-plated brass body resists mechanical impact and provides the shielding needed for flush-mount operation.
Applications
-
Cylinder Position Feedback: Detecting extended/retracted position of small pneumatic cylinders via a metal target on the rod or tie-rod.
-
Part Presence in Nest: Verifying a stamped or machined part is correctly seated in a fixture before clamping.
-
Index / Registration Mark: Sensing a ferrous tab on a rotating dial or cam for homing/sequence start.
-
Tight-Space Automation: Any application where an M12 or M18 sensor would be too large.
Note: For NPN output of the same M8 2mm flush sensor with cable, see NBN2-8GM30-E2. For M12 connector version (instead of cable) see NBB2-8GM40-E0 (M12 4-pin plug). The 3-wire brown/blue/black cable coloring follows IEC 60947-5-6 standard — observe PNP truth table: sensor sees metal → Black = HIGH (≈ supply voltage); no target → Black = LOW (0 V).
