Wenglor EB77VB7 Through Beam Sensor | 100m Range Emitter

Description

The Wenglor EB77VB7 Through Beam Sensor functions as the specialized emitter unit in an ultra-long-range sensing pair. By projecting a highly focused red light beam to a corresponding receiver, it creates a reliable optical barrier across distances as far as 100 meters. The transmitter is built with high light intensity, providing a significant switching reserve that allows the system to operate effectively in challenging conditions where dust or atmospheric haze might typically obstruct standard sensors.

In complex automation architectures, functional safety is a priority. The EB77VB7 includes an integrated test input feature that allows the control system to temporarily shut off the transmitter beam. This enables the system to verify the functional integrity of the entire through-beam circuit, ensuring the receiver identifies the interruption correctly. Constructed with a rugged ABS/PC housing, this sensor is designed to withstand mechanical vibrations and temperature fluctuations from -25 °C up to 60 °C, ensuring long-term stability and minimal maintenance in heavy industrial sectors.
