This is the 80cm variant of the E18-D80NK NPN- NO Adjustable IR Sensor Proximity Switch 3-80cm Range in Other Proximity Sensor & Modules. Available at ₹140.42 (₹119.00 + GST) with free shipping across India.
Product Description
- The E18-D80NK NPN-NO Adjustable IR Sensor Proximity Switch offers a compact solution by combining both a transmitter and receiver into a single photoelectric switch sensor. With an adjustable detection range of 3 to 80 cm, it provides flexibility for various applications. This versatile, cost-effective, and user-friendly sensor is perfect for tasks such as robot obstacle avoidance, interactive media systems, and industrial assembly lines.
- The sensor outputs a switching signal that changes based on the presence of obstacles: it remains high when no obstacles are detected and switches low upon detection. Equipped with a bright light positioned behind the probe, it efficiently identifies objects within its 3 cm to 80 cm detection range.
