Datasensing BX04SR/0A-HB79 Sensors

The Datasensing BX04SR/0A-HB79 Sensors are a robust area sensor kit designed for precision and reliability. Featuring four adjustable beams, this sensor operates within a nominal sensing distance of 0.3 to 2 meters, with a thermal drift of Sr at ?10%. The beams are spaced 30mm apart, providing a controlled height of 90mm and capable of detecting objects as small as Ø 15mm. The sensitivity can be finely tuned using a trimmer, and the sensor employs an emitter-receiver function principle. The BX04SR/0A-HB79 model includes both an emitter (BX04S/00-HB79) and a receiver (BX04R/AD-HB79), with NPN and PNP output types and a normally open (NO) output function. It boasts a switching frequency of 180Hz, with response times of 500µs for light/dark transitions and 5ms for dark/light transitions. Operating on a voltage range of 10 to 26VDC, it has a no-load supply current of 75mA and can handle a load current of up to 100mA, with a leakage current of just 10?A and an output voltage drop of ?2V at 100mA load. The sensor is equipped with LED indicators for easy status monitoring: green for power on the emitter, and yellow and red for output state and alignment on the receiver. It features a time delay before availability of ? 85ms and includes short-circuit and reverse polarity protection, as well as impulsive overvoltage protection. The sensor is housed in a durable aluminium enclosure with PBT housing material and a PC active head, ensuring mechanical protection rated at IP67. With a weight of 450g and dimensions of 45x145x20mm, the sensor is designed for easy installation using the supplied M12 plug connections, four M18x1 nuts, an adjustment key, and two 90° angled brackets. It is approved by CE and cULus, and complies with EMC compatibility standard EN 60947-5-2. The sensor can operate in temperatures ranging from 0°C to +50°C, making it suitable for various industrial environments.
