Pepperl Fuchs Proximity Sensors, specifically the NBB20-U1-E2 model, are highly reliable sensors that are designed to detect the presence or absence of objects within a 20mm range. These sensors operate using DC voltage and output a PNP signal. The sensors are designed to be installed flush with the object being detected and have a rated operating distance of 20mm. The NBB20-U1-E2 sensors are highly resistant to environmental factors such as extreme temperatures and exposure to liquids, with a degree of protection of IP68 / IP69K.
They have screw terminal connections for easy installation and can accommodate up to 2.5mm2 core cross-section conductors. Additionally, these sensors have a number of safety and compliance features, including reverse polarity and short-circuit protection, and UL and CCC approval. These sensors are ideal for use in a wide range of industrial automation applications and can be supplied by IndMALL Automation.
