Pepperl+Fuchs NBB20‑U1‑Z2 | Inductive Proximity Sensor | 20 mm | Block Housing | DC 2‑Wire
Overview
The NBB20‑U1‑Z2 is a block-style inductive proximity sensor with a robust flush-mount 20 mm sensing face. It offers dual NO/NC outputs, rotatable head for flexible positioning, and versatile DC 2-wire operation—ideal for metal detection in tight spaces and harsh industrial environments.
Key Features
-
Sensing distance: 20 mm flush mount
-
Rotatable sensor head with 360° visibility via two LEDs
-
2-wire DC operation with PNP output, switchable NO/NC
-
Wide supply range: 5–60 V DC
-
Configurable output up to 200 mA, with reverse-polarity and short-circuit protection
-
Rugged block housing in PA/metal, rated IP68/IP69K for harsh conditions
-
Switching frequency up to 250 Hz for fast applications
