The Omron E3S-DBP21 Photoelectric Sensor uses a retroreflective sensing method with an advanced MSR function to detect transparent objects up to a sensing distance of 3.5 meters. Powered by 10 to 30 VDC with a maximum consumption of 720 mW, it features a highly stable Red LED (624 nm) light source and PNP output configuration via a standard M12 connector. With a lightning-fast 0.5 ms response time, the sensor ensures seamless operation in high-speed bottling and packaging lines.
Its rugged build includes reversed polarity protection, short-circuit protection, and resistance to environmental disturbances such as vibration and shock. The E3S-DBP21 is protected under IP67 and IP69K ratings, making it ideal for washdown applications in food and beverage industries. With dual LED indicators for light detection and stability, setup becomes intuitive and error-free. Crafted from high-grade materials like PBT, PMMA, and stainless steel (SUS304), it combines lightweight design (approx. 60g) with durability.
This sensor is widely trusted by automation engineers for critical detection tasks requiring speed, reliability, and environmental resilience.
