Pepperl+Fuchs UBE800-F77-SE2-V31 233248 20-30VDC Miniature Through-beam Ultrasonic Sensor

1. Overview of the Pepperl+Fuchs UBE800-F77-SE2-V31 233248

The Pepperl+Fuchs UBE800-F77-SE2-V31 233248 is the most compact all-in-one transmitter-receiver ultrasonic barrier in the Pepperl+Fuchs F77 series. It utilizes an 800 mm beam window to detect objects of any material, color, or transparency, maintaining a reliable signal even in bright, reflective, or dusty environments. It is ideal for small assembly lines, precision machinery, electronics manufacturing, and logistics sorting.
