Equipped with dual circuits
Equipped with two switching safety outputs and a safety self-check function, the product is safer to use.
Anti-interference line synchronization
The light barrier features a line synchronization detection method. Line synchronization requires a green synchronization line connection, which enhances the light barrier’s anti-interference capabilities.
Multiple detection types
Three types are available, depending on the minimum detectable object size.
Impact-resistant, thick-walled, and durable housing
The H3EL features a sturdy metal housing, reliably protecting it from impacts such as collisions with workpieces and being stepped on.
