Supplied with full traceability and documentation.... Price & Availability Contact us for pricing / 询价 It features a diffuse sensing method with a 2-meter sensing distance, making it suitable for detecting a wide range of materials including opaque, translucent, and reflective objects. The sensor operates with a 12-24 VDC power supply and provides a PNP open-collector output, ensuring compatibility with most PLCs and industrial controllers. This sensor is housed in a rugged, cylindrical M18 metal body with an IP67 protection rating, making it resistant to dust, water, and harsh environmental conditions. The E3FB-DP21 uses a red LED (630 nm) as its light source, which is visible and aids in alignment. It features a built-in amplifier and offers a response time of 1 ms or less, enabling high-speed detection in production lines. The E3FB-DP21 is equipped with an indicator light for easy status monitoring and includes a sensitivity adjustment potentiometer for fine-tuning. Its operating temperature range of -25°C to 55°C and storage temperature of -40°C to 70°C ensure reliable performance in diverse industrial settings. With its robust construction and precise detection capabilities, the E3FB-DP21 is an ideal choice for applications such as packaging, material handling, and assembly lines. The Omron E3FB-DP21 is a compact photoelectric sensor from the E3FB series, designed for reliable object detection in industrial automation. Basic Product Information PNP open-collector output for easy integration IP67 protection rating for harsh environments Red LED (630 nm) light source for visible alignment Fast response time of 1 ms or less Built-in sensitivity adjustment potentiometer Rugged M18 metal cylindrical housing Wide operating temperature range (-25°C to 55°C) Diffuse sensing method with 2m sensing distance Technical Specifications Version & Model Difference The E3FB series includes various models with different sensing methods (diffuse, retro-reflective, through-beam) and output types (PNP/NPN). The E3FB-DP21 specifically has a diffuse sensing method and PNP output. Compared to the E3FA series, the E3FB offers a more compact design and improved performance. The 'D' in the model indicates diffuse, 'P' indicates PNP output, and '21' denotes the sensing distance and cable configuration. There are also variants with NPN output (e.g., E3FB-DN21) and different sensing distances. Application Scenarios Can the E3FB-DP21 be used in outdoor or wet environments? Yes, the E3FB-DP21 has an IP67 protection rating, which means it is dust-tight and protected against temporary immersion in water. However, it is recommended to avoid continuous submersion and ensure that the cable connections are properly sealed. What is the output type of the E3FB-DP21? The E3FB-DP21 features a PNP open-collector output. This means it provides a positive voltage signal when the sensor detects an object. It can switch up to 30 VDC and sink up to 100 mA, making it compatible with most PLCs and relays. Does the E3FB-DP21 have any adjustment features? Yes, the E3FB-DP21 includes a built-in sensitivity adjustment potentiometer that allows you to fine-tune the detection threshold. Additionally, it has an indicator light (orange LED) that illuminates when the output is active, aiding in setup and troubleshooting. What is the sensing distance of the Omron E3FB-DP21? The E3FB-DP21 has a maximum sensing distance of 2 meters for diffuse reflective sensing. This distance is specified for a standard white paper target (100x100 mm). Actual sensing distance may vary depending on the target's reflectivity and color.
