System Integration:

• Requires separate SICK fiber optic cables (through‑beam or diffuse reflection) for operation.

• Mounts on DIN rail via the BEF‑WLL180 mounting bracket (included).

• WLL180T‑P434 can be operated as a stand‑alone unit or in a bus configuration.

• In bus configuration, several sensors can be networked via an internal bus.

• The integrated anti‑interference logic prevents optical cross‑talk between amplifiers.

• Parameter settings can be copied to all other devices on the bus.

• Connects to standard industrial M8 4‑pin female cables.
