It operates on 10-30 V DC and provides an NPN output with selectable light-on or dark-on switching. The built-in M12 4-pin connector and right-angle face orientation simplify panel wiring in tight spaces. The 1 m diffuse range is the maximum for a standard 7 mm opaque target — real-world detection depends on reflectivity and background. The 0.5 ms response time keeps up with most conveyor and packaging lines. The NPN output sinks up to 100 mA; verify your PLC input card can source that current. The supply voltage tolerates 10-30 V DC with reverse polarity and short circuit protection built in, which reduces the risk of a field failure from a swapped wire. Rated IP67 and IP69K, the brass body and sealed connector hold up to washdown and high-pressure spray — a common requirement for food and beverage lines. The red LED emitter (visible) plus the indicator light give immediate alignment feedback during commissioning.","metaTitle":"Omron E3FB-DN23 Photoelectric Sensor, Diffuse, 1m, NPN, IP67","metaDescription":"Omron E3FB-DN23 M18 diffuse photoelectric sensor, NPN output, 10-30V DC, 1m range, IP67/IP69K, built-in M12 connector.
