Pepperl+Fuchs UB800-18GM40-U-V1 Ultrasonic Sensor | 800mm Range, 18-40V DC, PNP Output | IP67 Protection

1. Sensing Functionality​

The Pepperl + Fuchs UB800 - 18GM40 - U - V1 is a versatile diffuse - reflecting photoelectric sensor. It has a remarkable sensing range of up to 800 mm, allowing it to detect objects over a relatively long distance. This makes it suitable for applications where objects need to be detected from afar, like in large - scale industrial conveyors. The sensor uses visible red light for detection, which offers high visibility and accuracy. With its 18 - mm cylindrical housing, it can be easily integrated into various machinery setups. The built - in potentiometer enables easy adjustment of the sensing distance according to specific application requirements.​

2. Physical Build and Durability​

Housed in a robust nickel - plated brass body, the UB800 - 18GM40 - U - V1 is designed to withstand harsh industrial environments. The 40 - mm sensing face is made of high - quality PBT material, ensuring reliable performance. It has an IP67 protection rating, meaning it can resist dust ingress and temporary submersion in water. This durability is further enhanced by its ability to operate within a wide ambient temperature range of - 25 °C to +70 °C. The non - flush mounting design, along with the provided nuts for installation, offers flexibility in placement, and the tightening torque of 0 - 30 Nm ensures a secure fit.​

3. Electrical Characteristics​

Operating on a DC voltage range of 10 - 30 V, this sensor is compatible with many standard industrial power supplies. It features a 3 - wire PNP output configuration, which is widely used in automation systems. The sensor has a switching frequency of 0 - 1000 Hz, enabling quick response times to changes in the presence of detected objects. It also comes with reverse polarity protection, safeguarding the sensor from damage in case of incorrect voltage connection. The voltage drop is less than or equal to 2.5 V, and the operating current ranges from 0 - 100 mA, making it energy - efficient for continuous operation in industrial applications.
