The NBB20-U1-E2 is an inductive proximity sensor featuring a square, flush-mountable design. It has a sensing range of 0 to 20 mm and is suitable for industrial and commercial applications. The sensor includes a bidirectional, rotatable sensor head and offers protection ratings of IP68 and IP69K, making it highly resistant to harsh environments. It operates with a supply voltage of 10 to 30 V DC and provides a maximum current of 200 mA. The NBB20-U1-E2 is designed with features such as hysteresis of approximately 5%, reverse polarity protection, and short-circuit pulsing protection. It outputs a PNP normally open (NO) signal.
