SICK GLL170-P334 Fibre Optic Sensor, PNP, 250 µs, IP66

The SICK GLL170-P334 is a fibre optic sensor from the GLL170 series, with a PNP output and a 250 µs response time. It operates on 10–30 VDC and switches light-on or dark-on via the selectable mode. The M8 4-pin connector keeps wiring clean in tight panels — no flying leads to manage. Rated IP66, so it handles washdown and dust ingress in packaging or food processing lines where fibre optic sensing is preferred over through-beam for tight spaces. The visible red LED (650 nm typical) makes alignment visible to the naked eye — no IR viewer needed. Width is 10 mm, height 31.7 mm — fits standard 10 mm slot mounts used across the GLL170 family.
