Product Overview
The Omron E3FB-DP22 is the 300mm diffuse-reflective variant in Omron's E3FB family of M18 threaded photoelectric sensors. It is manufactured by Omron Corporation. Hengyixin Automation ships this sensor from our Xiamen warehouse with a 30-day DOA return window and a datasheet PDF included in the box.
Protection: IP67/IP69K Supply Voltage: 10-30 VDC Response Time: 0.5 ms Sensing Range: 300 mm

FAQ for E3FB-DP22
What's the difference between E3FA and E3FB?
E3FA is plastic (ABS) housing; E3FB is nickel-plated brass housing. Same optics, same electronics, same M18 thread. The E3FB is the right pick for harsh environments (coolant splash, solvent exposure, food-grade washdown); E3FA is the value pick for clean panels and indoor OEM machinery. Price difference is small (~$10-15 per unit).
What's the difference between E3FB-DP22 and E3FB-DP12?
E3FB-DP22 is 300mm sensing distance with M12 connector; E3FB-DP12 is 100mm sensing distance with M12 connector. Choose the 100mm version when the target is small (screw head, small component) and you need precise detection close-up. Choose the 300mm version for general-purpose part detection at typical machine distances.
How do I set Light-ON vs Dark-ON on the E3FB-DP22?
Pin 2 of the M12 connector controls the mode. Connect pin 2 (blue wire on standard XS2F cable) to 24V for Light-ON (output active when target is present, beam unbroken). Connect pin 2 to 0V for Dark-ON (output active when target is absent, beam broken). For most applications, Light-ON is the intuitive choice — output ON when you can see the part.
Can I use E3FB-DP22 with a PNP-input PLC?
Yes — the E3FB-DP22 has PNP output, which sources current on the output line. It connects directly to any PLC input that accepts PNP/sourcing signals. Most modern PLCs (Omron CP1, CJ2, NX, NJ) accept PNP by default. For older PLCs that only accept NPN, use the E3FB-DN22 (NPN output, same 300mm range).
