Pepperl+Fuchs NJ5-18GM-N

Inductive sensor

NJ5-18GM-N is an inductive sensor that provides non-contact detection of metal objects at distances up to 5 mm. It operates on 10-30 V DC power and features an NPN output. The sensor is housed in a cylindrical body with a diameter of 18 mm and is suitable for flush mounting. Its high reliability and precision make it ideal for use in industrial applications. The robust construction ensures long-lasting performance even in harsh environments, making it a reliable choice for various automation systems requiring accurate metal detection.
