Omron
The Omron E3FB-BP21 is a cylindrical axial coaxial retro-reflective photoelectric sensor featuring a nickel-plated brass M18 housing with IP67 and IP69K protection ratings. It utilizes a polarized red light source to deliver a sensing distance of 100 mm to 500 mm with a 0.5 ms response time, offering manual adjustment, Dark-ON and Light-ON operation modes, a PNP output type, and an M12 connector. Integrated transparent detection and P-opaquing functions operate on a 10-30 V power supply voltage. Submit the exact part number, quantity, and application requirements to receive a quote.
Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Omron references — within one business day.
