The Q126E: 72140 from Banner is an emitter-only photoelectric sensor, specifically designed to function as part of a through-beam sensor pair. It emits a visible red LED beam with a wavelength of 640 nm, offering clear alignment during installation and ensuring reliable detection when paired with a compatible receiver. With a maximum sensing distance of 2000 mm, it enables accurate long-range detection for conveyors, counting stations, and entry/exit monitoring in industrial environments.
Housed in a compact rectangular thermoplastic body and equipped with a 2-meter cable, the sensor provides excellent resistance to vibration and moisture. Its IP67 protection rating ensures long-term durability in dusty or wet environments, while the integrated polycarbonate lens supports optical clarity and impact resistance. The power supply range of 10β30 V DC makes it adaptable to most industrial control panels. Additionally, the sensor offers a fast response time of 1.3 ms ON / 0.9 ms OFF with a startup delay of 120 ms, allowing it to handle rapid processes efficiently. The LED status indicators provide visual feedback during operation and troubleshooting. Operating within a temperature range of -20Β°C to +55Β°C and humidity up to 95%, the Q126E is built for robust, real-world usage.
