The SICK WLL180T-L432 is a compact fiber-optic amplifier in the proven WLL180 series, engineered for high-speed, space-saving detection with plastic or glass fiber-optic cables. It delivers reliable switching performance for packaging machinery, electronics assembly, and general machine building where tiny targets, short mounting distances, and high cycle rates demand a fast, stable photoelectric solution.

With a fast NPN switching output and selectable light/dark operation, the amplifier provides deterministic control signals to PLC and I/O modules. A visible red LED at 650 nm simplifies alignment, while menu navigation and a teach-in button with an 8-digit 7-segment display streamline parameterization. Programmable timing functions (on-delay, off-delay, one-shot) from 0 to 9,999 ms enable precise signal conditioning. The device achieves ≤ 16 µs response time and up to 31.2 kHz switching frequency, features reverse-polarity protection, and withstands industrial environments thanks to an ABS/PC housing, IP50 protection, EMC compliance to EN 60947-5-2, and a 4-wire 2 m PVC cable for quick installation; operating temperature is −25 °C to +55 °C.

This combination of speed, configurability, and clear diagnostics makes the WLL180T-L432 a robust choice for OEMs and integrators standardizing on a dependable fiber-optic sensing platform, and it is supplied with a 1-year warranty to support long-term uptime and procurement peace of mind.
