The SICK GLL170-P332 is a fiber‑optic sensor amplifier (PNP output) designed to drive a GLL170 fiber optic sensing head, delivering a single output in a rugged IP66 enclosure. It ships with a 2 m connecting cable and provides light/dark switching plus an adjustable threshold via a built‑in potentiometer for repeatable sensing on packaging and automation lines. With a sensing range of 0 to 800 mm and a 3‑wire configuration, this module supports non‑contact edge or presence detection in harsh industrial environments.
